4. COLD FEED / GAS PURGE SWITCH

5. 2-STEP / 4-STEP TRIGGER SWITCH

Cold Feed and Gas Purge are combined into a two position momentary toggle switch.

To activate Cold Feeding, hold the switch in the UP position. The wire drive will feed electrode but neither the power source nor the gas solenoid will be ener- gized. Keeping the electrode and gun electrically “cold”. Adjust the speed of cold feeding by rotating the WFS knob.

GAS PURGE

The 2-Step / 4-Step switch has two set positions. Place the switch in the UP posi- tion for 2-step Trigger Operation and in the down position for 4-step Trigger Operation.

2 Step Trigger

2 Step trigger operation is the most com- mon. When the gun trigger is pulled, the welding system (power source and wire feeder) cycles through the arc starting sequence and into the main welding para-

•This feature is useful for threading the electrode through the gun.

•While the “cold feed” circuit is activated, adjust the wire feed speed using the WFS knob.

Hold with toggle switch in the DOWN position to activate Gas Purge and let the shielding gas flow. The gas sole- noid valve will energize but neither the power source out- put nor the drive motor will be turned on. The Gas Purge switch is useful for setting the proper flow rate of shield- ing gas. Flow meters should always be adjusted while the shielding gas is flowing.

meters. The welding system will continue

to weld as long as the gun trigger is activated. Once the trigger is released, the welding system cycles through the arc ending steps.

4-Step Trigger Operation

When the switch is in the 4-Step position the Power Feed™ 10M Single Wire Feeder provides trigger inter- lock capability (the operator can release the trigger and the system will continue to weld) and it also allows the operator to control the amount of time spent in the start and crater weld modes.

See Sequence of Operation for more information on the overall interaction trigger switch with the weld sequence.

The 2-Step / 4-Step trigger has no effect when welding with SMAW or CAG procedures.
