Lift Arc Dc Tig Operation - Unimig VIPER Operating Manual

LIFT ARC DC TIG OPERATION

Lift Arc ignition allows the arc to be started easily in DC TIG by simply touching the tungsten to the work piece and lifting it up to start the arc. This prevents the tungsten tip
sticking to the work piece and breaking the tip from the tungsten electrode. There is a particular technique called "rocking the cup" used in the Lift Arc process that provides
easy use of the Lift Arc function.
(1) Make sure the front end parts of the TIG torch are
correctly assembled, use the correct size and type of
tungsten electrode for the job, the tungsten electrode
requires a sharpened point for DC welding.
(4) With a small movement rotate the Gas Cup forward
so that the Tungsten Electrode touches the work piece.
IMPORTANT! - We strongly recommend that you check for gas leakage prior to operation of your machine. We recommend that you close the
cylinder valve when the machine is not in use.

(2) Turn on the Gas Valve located on the TIG torch
handle.
(5) Now rotate the Gas Cup in the reverse direction
to lift the Tungsten electrode from the work piece to
create the arc.
(3) Lay the outside edge of the Gas Cup on the work
piece with the Tungsten Electrode 1- 2mm from the
work piece.
