BLW-400SSW GENERAL INFORMATION  
BLW-400SSW FAMILIARIZATION  
Generator  
Excitation System  
The BLW-400SSW Welder/AC generator uses a brushless  
exciter to create rated output electricity. This system will  
use the mechanical energy generated by the 3600 RPM  
engine to spin the rotor (or armature) inside the welder/AC  
generator (or alternator end).  
The MQ Power Model BLW-400 welder/AC generator can  
provide 400 amps of welding current with a single operator  
or 200 amps of welding current simultaneously with two  
operators. When used as a welder/AC generator it can  
provide a maximum of 6,000 watts of power.  
The motion created by the rotor (which holds copper coils)  
spins inside a housing of permanent magnets called the  
"STATOR". A magnetic field is created by the stator and  
produces an electrical current.  
Control Panel  
The control panel is provided with the following:

Engine  
The BLW-400SSW is powered by a 4-cycle KUBOTA diesel  
engine.This engine is designed to meet every performance  
requirement for welder/AC generator.ReferenceTable 1, page  
10 for engine specifications.  
In keeping with MQ Power's policy of constantly improving  
its products, the specifications quoted herein are subject to  
change without prior notice.  
Idle Control Switch  
The BLW-400SSWWelder/AC generator is provided with an  
automatic idle (engine) control capability for noise  
suppression and fuel cost reduction. The automatic idle  
control feature automatically engages under a no-load  
condition.  
Engine Protection System  
Engine protection fail safe features are provided in the event  
of low oil pressure, high coolant temperature and failure of  
the battery to charge. If any of the above conditions occur  
while operating the welder/AC generator, it will cause a  
complete unit shut down.  
When the Idle Control Switch is placed in the ONposition,  
the engine revolutions will be approximately 2200 rpm (low-  
speed operation). When a load is connected to one of the  
output receptacles, the engine speed will automatically  
increase to about 3600 rpm (high-speed operation) within 10  
seconds. Conversely, when the load is removed, the engine  
speed will automatically drop back down to 2200 rpm within  
10 seconds.  
Battery Charge Indicator  
This unit is equipped with a protective device that signals  
an indicator and automatically stops the engine when the  
battery cannot be charged by the alternator.  
WaterTemperature Indicator  
This unit is equipped with an apparatus that signals an  
indicator and automatically stops the engine when the cooling  
water temperature becomes abnormally high. This apparatus  
will not function properly if the machine is operated with  
less than the proper amount of coolant.  
Oil PressureWarning Indicator  
If low oil pressure is detected while operating the welder/AC  
generator, the engine protection system will shut down the  
engine.  
If this condition (low oil pressure) should occur, please refer  
to the engine troubleshooting table (page 44) in this manual.

BLW-400SSW TRAILER SAFETY GUIDELINES  
Brakes  
Before any brake synchronizations adjustments can be  
made, the trailer brakes should be burnished-in by applying  
the brakes 20-30 times with approximately a 20 m.p.h.  
decrease in speed, e.g. 40 m.p.h. to 20 m.p.h. Allow ample  
time for brakes to cool between application. This allows  
the brake shoes to slightly be seated into the brake drum  
surface.  
If your trailer has a braking system, the brakes should be  
inspected the first 200 miles of operation. This will allow  
the brake shoes and drums to seat properly. After the first  
200 mile interval, inspect the brakes every 3,000 miles. If  
driving over rough terrain, inspect the brakes more  
frequently.  
Electric Brakes  
Figure 2 displays the major electric brake components that  
will require inspection and maintenance. Please inspect  
these components as required.  
Electrically actuated brakes (Figure 2) are similar to  
hydraulic brakes. The basic difference is that hydraulic  
brakes are actuated by an electromagnet.  
Listed below are some of the advantages that electric  
brakes have over hydraulic brakes:  
Electric Brake Adjustment  
1. Place the trailer on jack stands. Make sure the jack  
stands are placed on secure level ground.  
2. Check the wheel and drum for free rotation.  
3. Remove the adjusting hole cover from the adjusting  
slot at the bottom brake backing plate.  
4. With a screwdriver or standard adjusting tool, rotate  
the star wheel of the adjuster assembly to expand the  
brake shoes.  
"
"
"
"
Brake system can be manually adjusted to provide  
the corrected braking capability for varying road and  
load conditions  
Brake system can be modulated to provide more or  
less braking force, thus easing the brake load on the  
towing vehicle  
Brake system has very little lag time between the time  
the vehicles brakes are actuated and the trailers brakes  
are actuated  
5. Adjust the brake shoes outward until the pressure of  
the lining against the wheel drum makes the wheel  
difficult to turn.  
Brake system can provide an independent emergency  
brake system  
6. Rotate the star wheel in the opposite direction until the  
wheel rotates freely with slight lining drag.  
7. Replace the adjusting hole cover and lower the trailer  
to the ground.  
Remember in order to properly synchronize the tow vehicles  
braking to the trailers braking, can only be accomplished  
by road testing. Brake lockup, grabbiness or harshness is  
due to lack of synchronization between the tow vehicle  
and the trailer being towed or under-adjusted brakes.  
8. Repeat steps 1 through 6 on the remaining brakes.

BLW-400SSW TRAILER SAFETY GUIDELINES  
Tires/Wheels/Lug Nuts  
Tires and wheels are a very important and critical  
components of the trailer. When specifying or replacing the  
trailer wheels it is important the wheels, tires, and axle are  
properly matched.  
CAUTION:  
DO NOT attempt to repair or modify a  
wheel. DO NOT install in inner tube to  
correct a leak through the rim. If the rim  
is cracked,  
the  
air  
pressure in  
the inner tube may cause pieces  
of the rim to explode (break off)  
with great force and cause serious  
eye or bodily injury.  
Suspension  
The leaf suspension springs and associated components  
(Figure 3) should be visually inspected every 6,000 miles for  
signs of excessive wear, elongation of bolt holes, and  
loosening of fasteners. Replace all damaged parts  
(suspension) immediately. Torqued suspension components  
as detailed in Table 4.  
Tire Wear/Inflation  
Tire inflation pressure is the most important factor in tire life.  
Pressure should be checked cold before operation DO NOT  
bleed air from tires when they are hot. Check inflation  
pressure weekly during use to insure the maximum tire life  
and tread wear.  
Table 3 (Tire Wear Troubleshooting) will help pinpoint the  
causes and solutions of tire wear problems.  
CAUTION:  
Figure 3. Major Suspension Components  
NOTE  
ALWAYS wear safety glasses when removing  
or installing force fitted parts. Failure to  
comply may result in serious injury.

fasteners matched to the cone angle of the wheel. Proper  
procedure for attachment of the wheels is as follows:  
1. Start all wheel lug nuts by hand.  
2. Torque all lug nuts in sequence. See Figure 4. DO NOT  
torque the wheel lug nuts all the way down. Tighten  
each lug nut in 3 separate passes as defined byTable 5.

BLW-400SSW TOWING  
Towing Safety Precautions  
ALWAYS attach trailer's safety chain to bumper of towing  
vehicle.  
CAUTION :  
ALWAYS make sure the vehicle and trailer directional,  
backup, brake, and trailer lights are connected and are  
working properly.  
Check with your county or state safety  
towing regulations department before  
towing your generator. Vehicle towing  
codes and regulations can vary from state  
to state.  
The maximum speed (unless otherwise posted) for highway  
towing is 45 MPH. Recommended off-road towing is not to  
exceed 10 MPH or less, depending on type of terrain.  
To reduce the possibility of an accident while transporting  
the generator on public roads, always make sure the trailer  
(Figure 5) and the towing vehicle are in good operating  
condition and both units are mechanically sound.  
Place chocked blocks underneath wheel to prevent rolling,  
while parked.  
Place support blocks underneath the trailer's bumper to  
prevent tipping, while parked.  
The following list of suggestions should be used when towing  
your generator:  
Use the trailer's hand winch to adjust the height of the trailer,  
then insert locking pin to lock wheel stand in place, while  
parked.  
Make sure the hitch and coupling of the towing vehicle are  
rated equal to, or greater than the trailer "gross vehicle weight  
rating" (GVWR).  
Avoid sudden stops and starts.This can cause skidding, or  
jackknifing. Smooth, gradual starts and stops will improve  
gas milage.  
ALWAYS inspect the hitch and coupling for wear. NEVER  
tow a trailer with defective hitches, couplings, chains etc.  
Avoid sharp turns to prevent rolling.  
Remove wheel stand when transporting.  
DO NOT transport generator with fuel in tank.  
Check the tire air pressure on both the towing vehicle and  
the trailer.Also check the tire tread wear on both vehicles.  
ALWAYS make sure the trailer is equipped with a "Safety  
Chain".

BLW-400SSW INSTALLATION  
Indoor Installation  
Outdoor Installation  
Exhaust gases from diesel engines are extremely poisonous.  
Whenever an engine is installed indoors the exhaust fumes  
must be vented to the outside.The engine should be installed  
at least two feet from any outside wall. Using an exhaust  
pipe which is too long or too small can cause excessive  
Install the welder/AC generator in a location where it will not  
be exposed to rain or sunshine. Make sure the Welder/AC  
generator is on secure level ground so it cannot slide or  
shift around. Also install the welder/AC generator so the  
exhaust will not be discharged in the direction of nearby  
homes.  
bBacLk Wpre-s4su0re0aSnSd cWausetheINenSginTeAtoLhLeaAtTexIcOesNsively.  
Eliminate the danger of deadly carbon monoxide gas.  
Remember that exhaust fumes from any diesel engine are  
very poisonous if discharged in a closed room, but harmless  
if allowed to mix with the outside air. If the welder/AC  
generator is installed indoors, you must make provisions for  
venting the engine exhaust to the outside of the building.  
The installation site must be relatively free from moisture  
and dust. All electrical equipment should be protected from  
excessive moisture. Failure to do will result in deterioration  
of the insulation, and will result in short circuits.  
Foreign materials such as dust, sand, lint and abrasive  
materials will cause excessive wear to engine and alternator  
parts.  
CAUTION :  
An electric shock may happen when  
vibrators are used. Pay close attention to  
handling when operating vibrators and  
always use rubber boots and gloves to  
insulate the body from a electrical shock.  
CAUTION :  
Pay close attention to ventilation when  
operating the welder/AC generator inside  
tunnels and caves. The engine exhaust  
contains noxious elements.

Ground  
Extension Cable  
When electric power is to be provided to various tools or loads at  
some distance from the welder/AC generator, extension cords  
are normally used. Cables should be sized to allow for distance  
in length and amperage so that the voltage drop between the  
welder/AC generator and point of use (load) is held to a  
minimum.Use the cable selection chart (Table 7 ) as a guide for  
selecting proper cable size.  
The nut and ground terminal on the welder/AC generator  
should always be used to connect to a suitable ground.The  
ground path should be of #8 size wire.  
Connect the terminal of the ground wire between the lock  
washer and the nut and tighten the nut fully. Connect their  
end of the wire to a suitable ground.

Fuel  
Lubrication Oil  
Fill the fuel tank with clean diesel fuel. Do not fill the tank  
beyond capacity.  
Fill the engine crankcase with lubricating oil through the filler  
hole, but do not overfill. Make sure the welder/AC generator  
is level. With the dipstick inserted all the way, but without  
being screw into the filler hole, verify that the oil level is  
maintained between the two notches (Figure 12) on the  
dipstick. See Table 8 for proper selection of engine oil.  
Pay attention to the fuel tank capacity when replenishing  
fuel. Refer to the fuel tank capacity listed on page 10  
Specification Table 1.  
The fuel tank cap must be closed tightly after filling. Handle  
fuel in a safety container. If the container does not have a  
spout, use a funnel.  
CAUTION :  
Never fill the fuel tank while the engine is  
running or in the dark. Fuel spillage on a  
hot engine can cause a fire or explosion.  
If fuel spillage occurs, wipe up the spilled  
gasoline completely to prevent fire  
hazards.  
Coolant  
Use only drinkable tap water. If hard water or water with  
many impurities is used, the inside of the engine and radiator  
may become coated with deposits and cooling efficiency  
will be reduced.  
Figure 12. Engine Oil Dipstick  
An anticorrosion additive added to the water will help prevent  
deposits and corrosion in the cooling system. See the  
Kobota Engine Operator's Manual for further details.

BLW-400SSW PRE-SETUP  
CAUTION  
:
Cleaning the Radiator  
The radiator may overheat if the fins become overloaded  
with dust or debris. Periodically clean the radiator fins with  
compressed air.  
When adding coolant or antifreeze to the  
radiator, do not remove the radiator cap  
until the unit has completely cooled.  
Fan Belt Tension  
A slack fan belt may contribute to overheating, or to  
insufficient charging of the battery. Inspect and adjust it in  
accordance with the Kubota Engine Operator's Manual.  
Day-to-day addition of coolant or antifreeze is done from the  
reserve tank. See Table 9 for engine, radiator and reserve  
tank coolant capacities. Make sure the coolant level in the  
reserve tank is always between the "H" and the "L" markings.  
The fan belt tension is proper if the fan belt (Figure 5) bends  
7 to 9 mm (0.28- to 0.35 in.) when depressed with the thumb  
as shown in Figure 13 below.

The battery is sufficiently charged if the specific gravity of  
the battery fluid is 1.28 (at 68° F). If the specific gravity  
should fall to 1.245 or lower, it indicates that the battery is  
dead and needs to be recharged or replaced.  
NOTE  
Check to see whether the battery cables are loose. Poor  
contact may result in poor starting or malfunctions, always  
keep the terminals firmly tightened. Coating the terminals  
with a thin film of grease will help to inhibit corrosion.  
When the antifreeze is mixed with  
water, the antifreeze mixing ratio must  
be less than 50%.

BLW-400SSW LOAD APPLICATION  
CAUTION:  
Single Phase Load  
Always be sure to check the nameplate on the welder/AC  
generator and equipment to insure the wattage, amperage  
and frequency requirements are satisfactorily supplied by  
the welder/AC generator for operating the equipment.  
Motors and motor-driven equipment draw  
much greater current for starting than  
during operation.  
Generally, the wattage listed on the nameplate of the  
equipment is its rated output. Equipment may require 130—  
150% more wattage than the rating on the nameplate, as  
the wattage is influenced by the efficiency, power factor  
and starting system of the equipment.  
An inadequate size connecting cable which cannot carry  
the required load can cause a voltage drop which can burn  
out the appliance or tool and overheat the cable.  
The idle control is operated at minimum load capacity of  
100W. If the load capacity is less than 100W, change the  
idle control switch to the "OFF" position.  
NOTE  
If wattage is not given on the  
equipment's name plate, approximate  
wattage may be determined by  
multiplying nameplate voltage by the  
nameplate amperage.  
CAUTION:  
Before connecting this welder/AC  
generator to any buildings electrical  
system, a licensed electrician must install  
an isolation (transfer) switch. Serious  
injury or death may result without this  
transfer switch.  
WATTS = VOLTAGE x AMPERAGE  
The power factor of this welder/AC generator is 1.0. See  
Table 11 below when connecting loads.  
When connecting ordinary power tools, a capacity of up to  
the generating sets rated output (kW) multiplied by 0.8 can  
be used. Use Table 12 below for proper welding electrode  
size for power capacity.

Welding Cables and Polarities  
NOTE  
Connect the welding cables (Figure 14) to the welder's output  
terminals located on the control panel. The output terminals  
have (+) and (-) polarities. Select the appropriate polarities  
according to the application (See Welding Applications,  
Table 13).  
ALWAYS attach terminal connectors at  
the end of each cable. NEVER connect  
exposed or frayed wires (Figure 15)  
directly to the terminals. Exposed wiring  
may cause shocks or di-electric  
breakdown from poor contact.

Duty Cycle  
If the arc is too long or voltage too high the metal melts off the

However, the duty cycle depends upon the welding current  
and number of operators. Select the appropriate duty

electrode in large globules which wobble from side to side as  
the arc wavers, giving a wide, spattered and irregular bead–  
with poor fusion between original metal and deposited metal.  
If the arc is too short or voltage too low, there is not enough  
heat to melt the base metal properly and the electrode quite  
often sticks to the work. This gives a high, uneven bead,  
having irregular ripples and poor fusion.  
Table 14. Duty Cycle  
Duty Cycle %

4. Correct Travel Speed  
When your speed is too fast: your pool does not last long  
enough, impurities and gas is locked in. The bead is narrow  
and ripples pointed. When speed is too slow: the metal piles  
up, the bead is high and wide, with a rather straight ripple.

5. Correct Electrode Angle  
The electrode angle is of particular importance in fillet  
welding and deep groove welding. Generally speaking, when  
making a filet weld, the electrode should be held so that it  
bisects the angle between the plates and is perpendicular to  
the line of weld. If under cut occurs in the vertical member  
lowers the angle of the arc and directs the arc toward the  
vertical member.  
FIVE ESSENTIALS FOR PROPER  
WELDING PROCEDURES  
Besides the steady sizzling sound that a correct arc produces,  
the shape of the molten pool and the movement of the metal at  
the rear of the pool serve as a guide in checking weld quality.  
In a correctly made deposit, the ripples produced on the bead  
will be uniform and the bead will be smooth, with no overlap  
or undercut.  
CAUTION :  
1. Correct Electrode Size  
The correct choice of electrode size involves consideration of  
a variety of factors. Such as the type, position, and preparation  
of the joint, the ability of the electrode to carry high current  
values without injury to the weld metal or loss of deposition  
efficiency. The mass of work metal and its ability to maintain its  
original properties after welding, the characteristics of the  
assembly with reference to effect of stresses set up by heat  
application, the practicability of heat treatment before and/or  
after welding, the specific requirements as to welding quality  
and the cost of achieving the desired results.  
Always wear welding shield with correct filter  
shade when welding.  
NOTE  
Under the above conditions, the welder can  
supply a welding current of 120 amps, and  
the welder/AC generator can supply up to  
3 kW of power at either 120 or 240 volts.  
2. Correct Current  
If current on equipment is too high or too low, you are certain  
to be disappointed in your weld. If too high, the electrode melts  
too fast and your molten pool is large and irregular. If too low,  
there is not enough heat to melt the base metal and your  
molten pool will be too small, will pile up, and look irregular.
