Ref. 228 647-A

1Weld Process Selector Switch NOTICE − Do not switch while welding. Use switch to select type of weld output.

Wire (GMAW) Welding: Use a positive (+) position for Direct Current Electrode Positive (DCEP) and a negative (−) position for Direct Current Electrode Negative.

Stick (SMAW) and TIG (GTAW Welding): Use a positive (+) position for Direct Current Elec- trode Positive (DCEP) and a negative (−) posi- tion for Direct Current Electrode Negative. Use AC position for alternating current.

2 Coarse Range Switch

NOTICE − Do not switch while welding.

Use switch to select weld amperage range when Weld Process Selector switch is in Stick/ Tig position, or voltage range when switch is in Wire position.

.For best arc starts and when using weld

and generator power together, use a low Coarse Range setting with the Fine con- trol set at 7 or higher.

3 Fine Control

Use control to select weld amperage (Stick/ Tig) or voltage (Wire) within the range selected by the Coarse Range switch. Control may be adjusted while welding.

Set control at 10 for maximum generator power.

Weld output would be about 124 A DC based on control settings shown (80% of 60 to 140 A). Settings shown are typical for welding with a 7018 (1/8) electrode.

.See Sections 6-3thru 6-5for typical pro- cess connections and control settings.
