When using Kemppi AC TIG equipment for specific applications, it is also possible to prepare and maintain a small
point on the electrode tip (d). This improves the directional control of the welding arc and weld pool size.
Tip:
You can also prepare the basic tip formation for AC welding with the following technique:
1.
Adjust the welding current a little higher than required.
2.
Burn the arc over a waste piece of material, keeping the torch electrode in a vertical position.
3.
Extinguish the arc immediately when the electrode tip has formed rounded spherical surface, no larger
than the diameter of the electrode, holding the same torch position as the electrode cools during the
post gas cycle.
4.
Reduce the current setting to a level suitable for the work target and start welding.
Electrode tip length
The optimal protrusion (l) of the electrode tip measured from the gas nozzle tip depends on the electrode diameter,
welding current level and weld joint type.
Tip:
Cleaning the electrode with steel wool can improve ignition and overall welding properties, by removing
surface oxides.
