Welder Protection System
In the event of an overload, this welder/generator is equipped
with an welder protection system . If an overload is detected
while operating the welder/generator, the welder protection
system will shut down the engine.
Oil Pressure Warning Alarm
In the event of low oil pressure (engine), this welder/generator
is equipped with an engine protection fail safe system . If
low oil pressure is detected while operating the welder/
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 in this manual.
Excitation System
The SGW-250SS welder/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 generator
(or alternator end).
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.
Engine
The SGW-250SS is powered by an air-cooled, 4-cycle
HONDA gasoline engine. This engine is designed to meet
every performance requirement for generator. Reference
Table 1, page 9 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.
Figures 2 and 3 (pages 14-15) show the basic controls and
indicators for the SGW-250SS welder/generator.

Explanation of Chart:
This section is intended to provide the user with trailer ser-
vice and maintenance information. The service and main-
tenance guidelines referenced in this section apply a wide
range of trailers. Remember periodic inspection of the trailer
will ensure safe towing of the equipment and will prevent
damage to the equipment and personal injury.
It is the purpose of this section to cover the major mainte-
nance components of the trailer. The following trailer com-
ponents will be discussed in this section:
 Brakes
 Tires
 Lug Nut Torquing
 Suspension
 Electrical
 Brake Troubleshooting Tables
Use the following definitions with reading Table 2.
1. Fuel Cell - Provides an adequate amount of fuel for
the equipment in use. Fuel cells must be empty when
transporting equipment.
2. Braking System - System employed in stopping the
trailer. Typical braking systems are electric, surge, hy-
draulic, hydraulic-surge and air.
3. GVWR- Gross Vehicle Weight Rating (GVWR), is the
maximum number of pounds the trailer can carry, in-
cluding the fuel cell (empty).
SGW-250SS —TRAILER-SAFETY GUIDELINES
4. Frame Length - This measurement is from the ball
hitch to the rear bumper (reflector).
5. Frame Width - This measurement is from fender to
fender.
6. Jack Stand - Trailer support device with maximum
pound requirement from the tongue of the trailer.
7. Coupler - Type of hitch used on the trailer for towing.
8. Tire Size - Indicates the diameter of the tire in inches
(10,12,14, etc.), and the width in millimeters
(175,185,205, etc.). The tire diameter must match the
diameter of the tire rim.
9. Tire Ply - The tire ply (layers) number is rated in letters;
2-ply,4-ply,6-ply, etc.
10. Wheel Hub - The wheel hub is connected to the trailer’s
axle.
11. Tire Rim - Tires mounted on a tire rim. The tire rim must
match the size of the tire.
12. Lug Nuts - Used to secure the wheel to the wheel hub.
Always use a torque wrench to tighten down the lug
nuts. See Table 4 and Figure 5 or lug nut tightening and
sequence.
13. Axle - Indicates the maximum weight the axle can sup-
port in pounds, and the diameter of the axle expressed
in inches (see Table 3). Please not that some trailers
have a double axle. This will be shown as 2-6000 lbs.,
meaning two axles with a total weight capacity of 6000
pounds.
14. Suspension - Protects the trailer chassis from shocks
transmitted through the wheels. Types of suspension
used are leaf, Q-flex, and air ride.
15. Electrical - Electrical connectors (looms) are provided
with the trailer so the brake lights and turn signals can

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.
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:
NOTE
ALWAYS wear safety glasses when removing
or installing force fitted parts. Failure to
comply may result in serious injury.
Suspension
The leaf suspension springs and associated components
(Figure 2) 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.

Lug Nut Torque Requirements
It is extremely important to apply and maintain proper wheel
mounting torque on the trailer. Be sure to use only the
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 3. DO NOT
torque the wheel lug nuts all the way down. Tighten
each lug nut in 3 separate passes as defined by Table 5.
3. After first road use, retorque all lug nuts in sequence.
Check all wheel lug nuts periodically.
NOTE
NEVER use an pneumatic air gun to
tighten wheel lug nuts.

SGW-250SS —TOWING
To reduce the possibility of an accident while transporting
the generator on public roads, always make sure the trailer
(Figure 4) and the towing vehicle are in good operating
condition and both units are mechanically sound.
The following list of suggestions should be used when towing
your generator:
CAUTION :
Towing Safety Precautions
■ ALWAYS attach trailer's safety chain to bumper of towing
vehicle.
■ ALWAYS make sure the vehicle and trailer directional,
backup, brake, and trailer lights are connected and are
working properly.
■ 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.
■ Place chocked blocks underneath wheel to prevent
rollingrolling

rolling,
while parked.
■ Place support blocks underneath the trailer's bumper to
prevent
tippingtipping

tipping , while parked.
■ 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.
■ Avoid sudden stops and starts.This can cause skidding, or
jackknifing. Smooth, gradual starts and stops will improve
gas milage.
■ Avoid sharp turns to prevent rolling.
■ Remove wheel stand when transporting.
■ DO NOT transport generator with fuel in tank.
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.
■ Make sure the hitch and coupling of the towing vehicle are
rated equal to, or greater than the trailer "gross vehicle weight
rating" (GVWR).
■ ALWAYS inspect the hitch and coupling for wear. NEVER
tow a trailer with defective hitches, couplings, chains etc.
■ 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".
