6-3. Drive Motor Protection And Tip Saver/Short Circuit Protection
A. Drive Motor Protection
Drive motor protection circuit protects drive motor from overload. If drive motor becomes inoperative, cycle unit power
off and back on again.
B. Tip Saver/Short Circuit Protection
The tip saver/short circuit protection extends contact tip life and protects internal components from damage. If contact
tip is shorted to workpiece, the unit shuts down the welding output, but the fan continues to run. To resume operation,
release gun trigger to reset unit. If the contact tip has stuck to the workpiece, release gun trigger, turn off unit, and
remove contact tip from workpiece. Check contact tip and replace if damaged. Turn on unit to continue operation.
