Welding is potentially a very hazardous activity. It should only be attempted
by a trained welder with a thorough knowledge of proper welding tech-
niques and safety procedures. Be sure to read and follow the safety in-
structions and precautions described below.
Failure to use the proper gage of cable may lead to painful burns.
Precautions:
1. When using the welder, do not connect the generator
to a household circuit. This could cause damage to
the generator or to elecb'ical wiring or appliances in
the house.
2. For continuous operations, DO NOT exceed the rated
load capacity (6.0 kW). Substantial overloading will
cause the circuit beaker to switch off. Marginal over-
loading may not cause the circuit breaker to switch
off but it will shorten the service life of your welder/
generator.
3. Notice: Voltage is present at the welding cables
whenever the engine is running.
Welder Operation:
Welding Cable Selection:
An undersized cable will result in unacceptably high resistanceto
current flow. This resistance will shortenthe life of the generator
and can potentially make the welding cables hot enough to
cause painful burns. Whenever possible, refer to the cable
manufacturer's recommendations.

1. Put the engine switch in the OFF position. Turn the AC
circuit breaker OFF and remove any plugs fi'om the AC
receptacles.
2. Connect the welding cables to the welder's DC terminals.
See section on Welding Cable Selection to select the ap-
propriate cable size.
3. Start the engine and allow it to warm UPfor at least 3 min-
utes.
4. Turn the AC/DC (WELD) selector to the DC (WELD) posi-
tion.
5. Set the current adjustment knob to the proper current level
for the job being done. Make a sample weld on scrap
material to verify the correct electrode and current setting.

positive and negative cables,
Welding Duty Cycle:
The duty cycle is the percentage of time the welder can be oper-
ated within a 10 minute period. DO NOT operate the welder
beyond its duty cycle or performance may decrease and the ser-
vice life of the welder may be shortened.

Polarity Selection:
The welding terminals are labeled "+" positiveand =-" (negative).
Changing the paladty of the cables will affect the weld. Correct
polarity selection is dependent on the type of electrode you are
using and the type of material you are welding. Refer to the
electrode manufacturer's recommendations for best results. For
straightpolarity, attach the electrode cable to the negative termi-
nal and the ground cable to the positive terminal.
