I.2-Step/4-Step Selector (TIG only): Select either the 2-step or 4-step sequence for TIG welding.

Note: The foot remote control can be sub- stituted for the torch thumb switch in these steps.

—2-Step

1.To start the sequence, press and hold the torch thumb switch.

2.Gas flows for 0.5 seconds to purge the torch line of air.

3.The welding current starts with a preset upslope time of 0.2 seconds from the pre- set starting current of 15A to the selected output current

4.Release the thumb switch to end the welding sequence.

5.The welding current decreases from the selected output current to the preset fin- ish current over the preset downslope time, then the welding current shuts off.

6.The shielding gas continues to flow for the post-flow time selected.

—4-Step

1.To start the sequence, press the torch thumb switch.

2.The welding current starts at the preset starting current of 15 amps, and stays at that level while the torch thumb switch is depressed.

3.Gas flows for 0.5 seconds to purge the torch line of air.

4.Release the torch thumb switch at any time to raise the welding current to the selected output current over the preset upslope time of 0.2 seconds.

5.Press the thumb switch again to end the welding operation.

6.The welding current decreases to the pre- set finish current, and stays at the level while the thumb switch is depressed.

7.Release the thumb switch at any time to shut off the welding current.

8.The shielding gas continues to flow for the post-flow time selected.

J.AC/DC Selector: Use this switch to select AC or DC current output.

K.Pre-Flow Time Dial: This knob will control the amount of time (0–10 seconds) gas will flow through the TIG torch before the welding current in turned on.
