TIG Welding Thinwall Square tubing

Using the laywire technique along with 3/32' filler on thinwall square tubing helps with melting thru too much and pulling those oxides into the bead.

Clean metal, sharp tungsten, and good gas shielding are 3 keys

ADDITIONAL SETTINGS =   PRE FLOW = .5 SECPOST FLOW = 7 SEC

TIPS: KEEP A TIGHT ARC ..

practice restarts until they blend in

Aim for an arc length that is equal or less than the diameter of your tungsten electrode.

Torch angle can be forgiving provided your arc length is tight.

Keep the hot tip of the filler wire shielded by the argon envelope from the tig cup

Technique for Stopping and Restarting the bead

Being able to restart a TIG bead in a way that hides the restart is a great skill to work on.

One simple technique is to think of the crater where you stopped as a target with a bullseye.

Simple center up on the bullseye and increase amperage to match the crater and then proceed with the bead.
