IGNITION OF THE WELDING ARC.
The welder is equipped with HF (
high frequency) ignition
. While you keep pressed
the push-button on the handle of TIG torch, the welder will periodically give off a
high frequency spark, which can start a TIG welding arc. The welding arc will be
started once you have the tungsten electrode near the work piece, if the work-piece is
connected via earth clamp to the + of the welder. Generally, the tungsten electrode
should be held at a distance from the work piece which is the same as the electrode
diameter.
If the arc ignition is not successful, remove the tungsten electrode from the TIG torch
and grind it clean.
If you are working with DC welding process, make the tip of the electrode into a
point. If you are working with AC welding process, the tip of the electrode will
naturally form a small ball, and there is no need to make the electrode pointy. If,
during welding, you happen to dip the electrode into the weld pool, be sure to clean
the electrode, again by grinding it.
The Walter TIG welder can ignite the welding arc through the so-called
LIFT
ignition, also. The procedure of the ignition is then executed as followed: without
pressing the torch push-button, bring the tip of the tungsten electrode in contact with
the work-piece, and then press the torch button, and slowly raise the electrode. The
arc will be ignited. With software regulation of the lift ignition, there is no need to
scratch the electrode against the work-piece to establish a welding arc.
