Automatic selection of parameters when welding
with AC current ("AC Auto")
Recommended for non-professional operators. In
"Synergism" mode, the welding machine control
system will prompt the appropriate AC frequency
and AC balance.
Remote control ("Remote")
The welder can be adapted to control the torch.
Activate this function to turn on remote control (at
this time, the peak current on the control panel will
be turned off).
Gas pre-flow ("Pre-Flow")
Before the electric arc is induced, a gas pre-flow will
begin to protect the weld during its formation. The
recommended gas pre-flow time is 0.1 - 0.5 seconds.
