OPERATION - TIG
Before starng any welding acvity ensure that you have suitable eye protecon and
protecve clothing. Also take the necessary steps to protect any persons within the welding
area.

2T mode (normal trigger control)
The 2T (↑↓) LED light will illuminate when the power source is in 2T welding mode. In this mode, the
torch trigger must remain pressed (closed) for the welding output to be acve. See example below:
Press and hold the torch trigger to acvate the power source, the gas valve and gas will ow.
Aer the gas pre ow me ends, HF discharge begins and then the welding arc will ignite and then the
current rises up (slope up me) to the welding
current value gradually unl you achieve the
preset welding current.
When the torch switch is released, the current
begins to drop gradually (slope down me)
and when it drops to the minimum current
value, the welding output is cut o and the gas
valve will close, once the post ow me ends,
this is the end of the welding process.
If the torch switch is pressed down during the
current downslope period, the current will rise
up again to the preset welding current value
and the slope out process will only start again once the torch switch to be released.
4T (latch trigger control)
The 4T ↕↕ LED will illuminate when the power source is in 4T welding mode, this trigger mode is mainly
used for long welding runs to assist in reducing operator nger fague. In this mode the user can press
and release the torch trigger and the output will remain acve unl the trigger switch is depressed again
and released.
In 4T mode, the gas valve opens when the
torch switch is pressed down, aer the
pre ow me ends, HF discharge occurs which
ignites the welding arc. Once the welding arc
has successfully ignited the inial current
value is acve and the torch switch can now
be released, the welding current rises up to
the preset welding current value gradually
and you will connue to weld your material.
To nish welding, simply press the torch
switch down again and the current will begin
to gradually drop (slope out me) to the nal current value. When the torch switch is released the current
output is cut o and the gas will connue to ow unl your preset post ow me has elapsed.
