TIG welding is particularly useful when high quality standards are required and when
welding thin sheet.
Before using the Caddy TIG HF for TIG welding, it must be equipped with a TIG torch
with trigger switch, a cylinder of argon, an argon regulator, tungsten electrodes and, if
necessary, suitable filler metal.
Selecting the TIG process, in order to strike the arc, you only need to put the tip of the
tungsten electrode near the workpiece and to press the trigger switch; an high frequency
(HF) discharge will strike the arc.
When the TIG LIFT START welding process has been selected the arc ignition is obte-
ned touching the workpiece with the tip of the tungsten electrode, pressing the trigger
switch and lifting the electrode gently to estabilish the arc. In this way the short circuit
current is maintained to a minimum level, in order to prevent the wear of the tungsten
electrode, and to reduce contamination of tungsten in the weld pool.
