WARNING:
After installing new wire spool, make sure welding wire is inserted into torch hose liner
and wire tension knob is correctly adjusted before pulling welding torch trigger.
The duty cycle rating of a welder defines how long the operator can weld and how long the welder
must be rested and cooled. Duty cycle is expressed as a percentage of 10 minutes and represents the
maximum welding time allowed. The balance of the 10-minute cycle is required for cooling.
Your new welder has a duty cycle rating of 20% at the rated output. This means that you can weld for
two (2) minutes out of 10 with the remaining eight (8) minutes required for cooling. (See Table 2).

CAUTION:
Do not constantly exceed the duty cycle or damage to the welder can result. If
you exceed the duty cycle of the welder, an internal thermal protector will open, shutting off all
welder functions. After cooling, the thermal protector will automatically reset and the welder
will function normally again. However you should wait at least ten minutes after the thermal
protector opens before resuming welding. You must do this even if the thermal protector
resets itself before the ten minutes is up or you may experience less than specified duty cycle
performance.
