Cooling Mode: Fan Cooling Insulation Grade: F
Internal Thermal Protection
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 ma-
chine, and does not require any user action. However, you should wait at least ten minutes after the thermal protector engages be-
fore resuming welding. You must do this even if the thermal protector resets itself before the ten minutes is up or you may experi-
ence less than specified duty cycle performance.
CAUTION: DO NOT REGULARLY EXCEED THE DUTY CYCLE OR DAMAGE TO THE WELDER CAN RESULT.
Welding Preparation
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 smother potential fires that may occur.
To properly prepare for welding with your new welder, it is necessary to:
Read the safety precautions at the front of this manual.
Ÿ
Prepare an organized, well-lit work area.
Ÿ
Provide protection for the eyes and skin of the operator and bystanders.
Ÿ
Attach the work clamp to the bare metal to be welded, making sure of good contact.
Ÿ
When MIG, MAG, Aluminum Welding or Flux-Cored Arc Welding, make sure that the wire-roller groove in the roller corresponds to
Ÿ
the diameter and type of wire being used.
Plug the machine into a suitable outlet, recommend NEMA5-50.
Ÿ
Completely open the gas cylinder valve. Adjust the gas pressure regulator to the correct flow rate. (Not applicable to Stick "SMAW"
Ÿ
process).
