Setting Welding Controls ‐ Time and Current
The time and current controls are located on the front of the welder. The controls consist of a
Time Button, Current Button, Adjustment Dial, and a Fine/Coarse Switch. The digital display will
indicate the settings chosen during setup.
When setting time or current, depress and hold down appropriate button, and turn Adjustment
Dial clockwise or counter‐clockwise to the correct setting on the digital display.
Use the Fine/Coarse Switch for setting the appropriate time or current ‐ this will toggle between
10’s or 100’s of amps and 10th’s and 100th’s of a second.
To adjust gas purge time, hold both the TIME and AMPS buttons and turn Adjustment Dial. The
setting is saved when the buttons are released.
