3.4.5 Welding with Repeated Ending Arc
Welding with repeated ending arc is mainly used to fill up the craters and arc holes created by
ending arc. 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 repeated
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 3-13 shows the control panel where the parameters have been set.
Figure 3-13 Selecting the mode of welding with repeated ending arc
When the switch of the welding torch is turned to ON after parameters are set, an arc is
generated. When the switch of the welding torch is turned to OFF, welding arc generation is
locked. When the switch is turned to ON again, the ending arc is generated using the ending arc
voltage and current. When the switch is turned to OFF again, welding stops. If the welding torch
is not used within 2 seconds, welding with repeated ending arc stops. If the power switch is
turned on within 2 seconds, welding with repeated ending arc is performed again. This
procedure repeats when you repeat the preceding operation. Figure 3-14 shows the welding
procedure.
