7. TIG welding is selected
7. Welding torch trigger 2-sequence function
Gas flow starts, when the torch switch is pressed. After preset pre-gas time welding starts and current
will rise to the welding level within the up-slope time. Release the torch switch, and the current
starts to drop and after the selected down-slope time the arc is broken. After this, the shielding gas
will flow for the time selected.
7. Welding torch trigger 4-sequence function
Gas flow starts, when the torch switch is pressed. Release the torch switch, the ignition spark
ignites the arc and the current will rise to the welding level within the up-slope time. Press the
torch switch down. The welding continues. Release the torch switch, and the current starts to drop
and after the selected down-slope time the arc is broken. After this, the shielding gas will flow for
the time selected.
8. HF-contact
TIG arc can be started either with high frequency (HF) or without (contact ignition). HF ignition
is chosen by pressing the HF/Contact button No. 8 to turn on the HF light.
9. Remote
If you choose to adjust the welding current with a remote control unit you need to connect the
unit and select remote button. The panel led switches off and then you select the unit. There is an
automatic recognition of remote control units with potentiometers and only the symbol of a unit
connected can be chosen. The foot pedal control works only in 2T.
10., 11. and 17. Adjustment of parameters
To select welding parameters you only need to use two buttons arrow-left and arrow-right.
Adjustment is done with the potentiometer. By pressing the return button adjustment of parameter
goes straight to welding current. The display shows automatically numeric values and the units
of the parameters. When you adjust parameters, you can see the value on the numerical display.
After 10 seconds, the display will return to the welding current.
