Ignition modes in TIG welding

TIG ignition modes determine the way in which the welding arc is ignited. Two ignition modes are available in TIG welding: Lift TIG ignition (DC TIG only) and High Frequency (HF) ignition.

Lift TIG ignition (DC TIG current mode only)

In Lift TIG ignition you briefly touch the work piece with the electrode, then press the trigger and lift the electrode to a small distance from the work piece. The Lift TIG ignition must be activated in the control panel. Also known as “Touch ignition” or “Contact ignition”.

 

High Frequency (HF) ignition

In HF ignition, a press on the torch trigger produces a high voltage pulse that creates a spark to ignite the arc. The HF ignition mode is always ON in AC TIG current mode.

>>  To set the HF ignition mode ON/OFF in DC TIG current mode, long-press the control panel's welding parameters button.
