current (or adjusted to the required value in advance, generally adjusted to 60 to 70% of the
normal welding current), so that the depression at the end of the welding can be filled.
When the welding torch switch is released again, the wire is immediately braked to stop, and
the ignition state is reduced to the burn-in voltage. When the welding current is zero, the
arc-breaking is completed, the gas supply is stopped, and the welding process is completed.

2-Step weld operation (Non initial and crater)
● Mainly used for spot welding, repeated short welding, thin plate welding.
● Press the button“2-step/4-step”to “2-step”, Turn on the torch(ON) and start welding,
OFF torch then end welding.
6, Weld condition example
The reference value values of the standard conditions are provided in Tables 6 and 7,
which facilitates quick setting of parameters. In actual welding, please correct it according to
the material to be welded and the welding position to find suitable welding conditions.
