If you exceed the duty cycle of the welder, the thermal protection system will engage, shutting off all welder output. After
cooling, the thermal protector will automatically reset and the welding functions can resume. This is normal and automatic
behavior of the machine, and does not require any user action. However, you should wait at least ten minutes after the
thermal protector engages 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.
CAUTION: DO NOT REGULARLY EXCEED THE DUTY CYCLE OR DAMAGE TO THE WELDER
CAN RESULT.
An important factor in making a satisfactory weld is preparation. This includes studying the process and equipment and
practicing welding before attempting to weld finished product. An organized, safe, ergonomic, comfortable, and well-lit
work area should be prepared for the operator. The work area should specifically be free of all flammables with both a
fire extinguisher and a bucket of sand available.
To properly prepare for welding with your new welder, it is necessary to:
• Read the safety precautions at the front of this manual.
• Prepare an organized, well-lit work area.
• Provide protection for the eyes and skin of the operator and bystanders.
