SECTION 5 − OPERATION

5-1. Controls

1Power Switch W/Indicator Lamp

When the switch is turned on, the lamp lights to indicate power has been applied to the unit.

YIf the indicator lamp does not light when the power switch is turned on, replace the switch.

NOTE: This unit has over-tempera- ture protection. If unit becomes hot or if the duty cycle is exceeded (see Section 4-2), weld output shuts down and the fan stops running. The indicator lamp on the power switch remains on.

YWhen the unit has cooled down, the fan restarts air flow, and weld output is present at the weld output terminals and/or at the elec- trode.

2Amperage Adjustment Control

3Amperage Range Indicator

Turn handle clockwise to increase amperage as indicated by the am- perage range indicator.
