LIFT ARC DC TIG OPERATION FOR MMA-TIG160/200PFC
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.
(6) 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.
(7) Turn on the Gas Valve located on the TIG torch handle.
(8) Lay the outside edge of the Gas Cup on the work piece with the Tungsten Electrode 1- 2mm from the
work piece.
(9) With a small movement rotate the Gas Cup forward so that the Tungsten Electrode touches the work
piece.
(10) Now rotate the Gas Cup in the reverse direction to lift the Tungsten electrode from the work piece to
create the arc.

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.

6) Assemble front end parts of the TIG torch,
fitting a sharpened tungsten suitable for DC
welding.
