Torch trigger operation and current

1T/Spot welding mode:
1. Push the torch trigger: arc is ignited and
current rises to the preset value.
2. When the spot welding time is up, current
drops gradually, and arc stops.
Note: Spot welding time is 1/10 of the
upslope time.
2
Standard 2T mode:
1. Push the torch trigger: arc is ignited and
current rises gradually.
2. Release the torch trigger: current drops
gradually, and arc stops.
3. If push the torch trigger again before arc
stops, the current will gradually rise again,
and then turn to 2.

Standard 4T mode:
1. Push the torch trigger: arc is ignited and
current reaches the initial value.
2. Release it: current rises gradually.
3. Push it again: current drops to pilot arc
current value.
4. Release it: arc stops.
When reading the above table, please note:
• Whether arc ignited by HF or by striking the electrode, and no matter what kind of operation mode is selected, after arc is
ignited successfully, it enters into initial current, and later into operational mode control.
•
Some operation modes adopt the exit mode by pushing the torch trigger. The operator should release it after exiting
welding. In this way, another welding operation can be entered by pushing the torch trigger.
• Current curves in all operation modes are drawn on the assumption that the machine works in DC TIG mode. If the machine
works in pulsed TIG mode, the current curve appears a pulse shape; if the machine works in AC TIG mode, the current
curve appears a variable polarity pulse shape.
•
Customarily, the TIG operation modes most widely used are 2T and 4T, which exactly correspond to operation mode 2 and
4 for this machine respectively.
