Pre-TIG Welding tips:

Model WT6100

Pre-TIG Welding tips:

TIG welding is much harder to master than other welding processes. Experience welding with an Oxy- Acetylene (flame power) torch will help greatly with learning TIG welding.

CLEAN the area to be welded. Cleanliness is imperative. You can’t get the base metal too clean. There is no flux to float off impurities with the TIG process.

Cut filler metal rods to shorter lengths for easier control. Usually TIG filler metal comes in 36” lengths. It is much easier to handle if it is 18” or 12”. Clean the filler metal with alcohol and a clean white cloth. Dirt and dust contaminate a weld.

TIG welding gives off less light than other arc welding processes, but you must still use a #10 minimum shade welding lens to protect your eyes.

Get yourself into a comfortable position to weld. Seated with your arms supported by a welding table or by the work-piece.

Striking an arc:

Turn on the welder and the gas valves on the gas bottle, regulator, and torch.

Rest the torch nozzle on the base metal to be welded without the Tungsten electrode touching the base metal.

Rotate the torch so that the Tungsten electrode lightly touches the base metal and immediately lift off or rotate off as the arc ignites.

Keep the Tungsten 1/8” - 3/16” from the work piece while maintaining the arc.

As the metal gets hot, it becomes a shiny orange molten puddle. Dip the filler metal rod in the puddle to add filler metal.

Tips while TIG welding:

Always let the filler metal rod be melted by the molten puddle. NOT by the torch.

Never touch the hot Tungsten electrode to the molten puddle. The molten steel will be wicked up by the Tungsten, contaminating the electrode.

When you contaminate the Tungsten with steel, stop welding and re-grind the point of the electrode, removing the steel contamination.

When you burn a hole through the base metal, stop welding and let the weld cool before re-starting the arc.

Before making an important TIG weld, practice on a test piece. TIG welding is an art, and practice improves quality.

There is a lot of self-satisfaction to mastering this welding process and seeing that perfect weld.
