Making a TIG Weld:

1.Connect the work cable to the positive “+” output terminal.

2.Connect the TIG torch to the negative “-“ output ter- minal.

3.Connect the gas line from the TIG torch adapter to the gas regulator connected to the gas bottle.

4.Open the gas valve on the gas bottle and adjust the gas regulator to approximately 20-30 cfm.

5.Set the amperage based on material thickness:

Steel Thickness	Amperage Setting
(1/16”) 1.6mm	60-90 Amps
(1/8”) 3.2mm	75-120 Amps
(3/16) 4.8mm	125-150 Amps

6.Turn machine on.

7.Turn the gas valve on the torch to start shielding gas flowing.

8.Touch the tungsten to the work piece and pause for a second.

9.Slowly lift the tungsten off the work piece to estalish the arc. (Note: Rocking the torch back onto the ceramic shielding cup is an easy way to do this steadily.)

10.With the torch pointed in the direction of travel angled about 75 degrees to the work piece slowly move the torch in the direction of travel. Maintain about a 1/4” distance from the tungsten to the work piece while moving. Apply filler metal to the weld puddle by dipping the filler rod into the weld puddle allowing it to melt off and being careful not to touch the filler metal to the tungsten electrode.

11.At the end of the weld lift the TIG torch quickly away from the work piece to break the arc.

12.Turn off torch gas valve.

13.Turn machine off.
