HF High-frequency ignition

The arc is ignited by means of a high frequency/voltage discharge, the discharge stops as soon as welding current
begins to circulate or after a timeout (3s). This type of ignition does not require the workpiece to be touched with
the electrode tip. Unlike contact ignition, with HF ignition, there is no risk of contaminating the workpiece with the
tungsten electrode. Always try to ignite the arc at a maximum distance of 2-3 mm from the workpiece.
CEBORA WinTIG range power sources comply with regulations governing strikers in the welding field. Take care
when working with this type of procedure. Under certain circumstances, HF ignition may involve an electric shock
that is perceptible but not damaging to the operator. To avoid this, wear appropriate equipment and take care not
to work in wet or humid environments.

Lift contact ignition

This type of ignition involves the electrode coming into contact with the welding workpiece.
as follows:
1- Touch the workpiece
2- Press the torch trigger: a very low current now begins to circulate in the workpiece
spoil the electrode at the stage when it is
3- Lift the electrode tip from the workpiece: the electric arc is now triggered, the required welding current begins to
circulate in the workpiece and the shielding gas flow is activated.

Evo Lift ignition

This type of ignition is particularly well-suited for precision spot welding. It allows the workpiece to be contaminated
as little as possible at the ignition point. The starting sequence is as follows:
1- Touch the workpiece with the electrode tip.
2- Press the torch trigger:
3- Lift the electrode tip; as soon as the electrode is raised, a high frequency/voltage discharge is generated which
ignites the arc.
