Turn power On and loosen shield cup. If shutdown system works properly, Cup light comes on. If not, turn power Off and have a factory authorized service agent check unit.

If system works properly, retighten cup. Power must be reset whenever the cup shutdown is activated.

Check shield cup shutdown system once a week.

A flashing Cup light indicates that the torch consumables are stuck or worn and should be inspected and/or replaced (see

Section 6-3).

3 Temp Light

Lights if power source overheats or when ambient temperature is below −40° C (−40° F). If unit overheats, allow fan to cool unit for 15 minutes (see Sections 4-3).

4 Power/Temp Lights

When both lights flash, the com- pressor current limit was exceeded either above or below its operating range. The lights flash for 15 sec- onds before the torch can be retrig- gered. If this condition continues during unit operation, have a facto- ry authorized service agent check unit.
