 BASIC WELD CYCLE EXPLANATION

Pre Gas

Selection for gas flow time prior to the arc starting.

Start Current

Selection for the amount of amps required at the start of the weld.

UpSlope

Selection for the transition time from Start Amperage to Peak Amperage.

Peak Current

Selection for the Maximum Welding Amperage required during welding.

Pulse

Selection for Pulse or No Pulse.

Base Current only when Pulse is Selected

Selection for the Base Welding Amperage required during welding.

DownSlope

Selection for the transition time from Peak Amperage to Finish Amperage.

Crater Arc Current

Selection for the amount of fill at the end of the weld

Post Gas

Selection for gas flow time after the arc finishes.

AC WELDING ONLY

Balance

Selection to adjust the balance of the AC wave form in AC TIG mode. Adjustment of
the arc to be balanced, penetrating or oxide cleaning during AC TIG welding
