LIFT ARC DC TIG Operation for RAZOR
145/
210
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)
Check that your polarity is correct for DC TIG welding
(7)
Carefully open the valve of the gas cylinder, set the flow to 21-30cfh
(8)
Set the welding current using the amperage control dial
(9)
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.
(10)
Lay the outside edge of the Gas Cup on the work piece with the Tungsten Electrode 1/16 in from the
work piece. Press the trigger button on TIG torch to start the gas flow.
(11)
With a small movement rotate the Gas Cup forward so that the Tungsten Electrode touches the work
piece.
(12)
Now rotate the Gas Cup in the reverse direction to lift the Tungsten electrode from the work piece to
create the arc.
(10) Lay the outside edge of the Gas Cup on
the work piece with the Tungsten Electrode
1/16infrom the work piece. Press the trigger
button on TIG torch to start the gas flow.
(11) With a small movement rotate the Gas Cup
forward so that the Tungsten Electrode touches
the work piece.
(12) Now rotate the Gas Cup in the reverse
direction to lift the Tungsten electrode from the
work piece to create the arc.
(9) Assemble front end parts of the TIG torch,
fitting a sharpened tungsten suitable for DC
welding.
(8) Set the welding current using
the amperage control dial
(7) Carefully open the valve of the gas
cylinder, set the flow to
21-31cfm
