3.4.4 Welding with Ending Arc
After welding, you can use ending arc to fill up the craters and arc holes created during welding.
Four steps must be performed, including turning on and turning off the welding torch.
The procedure is as follows:
1. Press the Welding control button and switch to the mode of welding with ending arc.
2. Use the current and voltage adjusting knobs on the wire feeder to set the welding current
and voltage.
3. Press the Ending arc current and Ending arc voltage buttons, and use the
knob on the control panel to set the ending arc current and ending arc voltage.
4. Figure 3-10 shows the control panel where the parameters have been set.
