Yeswelder YWM-211P, Operator'S Manual

Page: 18 / 40

If you exceed the welding machine duty cycle, the thermal protection system will engage, shutting off all welding current output.
After cooling, the thermal protector will automatically reset, and the welding functions can resume. The user needs to know it is the
expected behavior of this machine. However, it would be best if you waited 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.
Internal Thermal Protection
The key to making a good weld is preparation. It includes studying the process and equipment and practicing welding before
attempting to weld the finished product. An organized, safe, ergonomic, comfortable, and well-lit work area should be prepared for
the operator. The work area should be free of all flammables, with a fire extinguisher and a bucket of sand available to smother
potential possible fires.
To properly prepare for welding with your new welder, it is necessary to:

Ÿ
Read the safety precautions at the front of this manual.
Ÿ
Prepare an organized, well-lit work area.
Ÿ
Protect the eyes and skin of the operator and bystanders.
Ÿ
Attach the work clamp to the bare metal to be welded, ensuring good contact.
Ÿ
When MIG/MAG, Aluminum Welding, ensure that the wire-roller groove in the roller corresponds to the diameter and type of wire
used.
Ÿ Plug the machine into a suitable power outlet, and recommend NEMA6-50.
Ÿ
Completely open the gas cylinder valve. Adjust the gas pressure regulator to the correct flow rate. (Not applicable to Stick welding
/ SMAW).
