Torch operating mode ("2T/4T")
2T mode: when the torch button is pressed, welding
starts. The button must be pressed to continue.
Then the button is released, welding will be stopped.
4T mode: When the torch is pressed and released,
welding begins. When pressed again and released,
welding will stop. The 4T mode is recommended for
longer welding.
Pulse mode
The choice between pulsed or non-pulsed welding.
Pulsed TIG welding occurs when the output current
(amperage) changes from high to low.
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.
