OPERATION - TIG
Before starting any welding activity ensure that you have suitable eye protection and
protective clothing. Also take the necessary steps to protect any persons within the welding
area.
TIG operation steps
After the parameters are set appropriately, you can then open the gas valve of the cylinder, and adjust
the gas regulator to the desired gas flow.
Keep the torch 2 - 4mm away from the work piece and then press the torch trigger.
Gas will flow followed by the HF and the arc is ignited.
Once the arc is ignited the HF will cease and the current rises up to the preset value and welding can be
carried out.
After releasing the torch trigger, the current begins to decrease automatically to the crater current value.
Then, the arc stops with the gas continuing to flow for the post flow time and welding ends.
Parameter autosaving
The parameters having been adjusted will be autosaved in the parameter group currently used.
Please Note: no autosaving will be done in the case that no welding is done after parameters are adjusted
and the machine was turned off in 5 seconds time.
When the machine is next turned on, the parameters in this parameter group are just the parameters
used last time.
When the welding mode and operation mode are reselected, autosaving will be done in 10 seconds.
See page 15 for manual saving procedures which are available for this machine via the channel key.
