2-step spot welding procedure
1. Press torch step button
The set gas pre-flow time starts to run and the gas valve opens. The arc is
ignited after the gas pre-flow time has elapsed. The welding current automatically
sets itself to the starting current. After the upslope time has elapsed, the welding
current reaches the preset value I1. The set spot welding time starts to run. After
the spot welding time has elapsed, the current reduces in accordance with the
preselected downslope time to the value set for the end crater current, and
switches itself off automatically after the final current time has elapsed.
2. Release torch step button
The inert gas flows in accordance with the selected gas post-flow time.
