Hobart TIG welders

Manufacturer profile: Hobart Tig Welding

A guide to Hobart Tig Welder Selection and Applications

From Hobart's site: "Often called TIG welding (Tungsten Inert Gas), this welding process joins metals by heating them with a tungsten electrode which should not become part of the completed weld. Filler metal is sometimes used and argon inert gas or inert gas mixtures are used for shielding. Consumables: tungsten electrode, filler metal, shielding gas. The TIG process requires a high skill level."

The Hobart Tigmate TIG Welder

The TIGMATE™ is a complete AC/DC, TIG and Stick welding package. All you need is a bottle of argon shielding gas or your choice of Stick electrodes and you're ready to start welding. In the TIG mode, the TIGMATE™ offers superior performance: 18 gauge to 3/16 in. (1.2 to 4.8 mm) steel and stainless steel; 14 gauge to 3/16 in. (1.8 to 4.8 mm) aluminum. For thicker metals, take advantage of the Stick mode using 3/32 and 1/8 in. (2.4 and 3.2 mm) electrodes.

TIG welding tips from Hobart

  1. Use Argon shielding for steel, stainless, and aluminum.

  2. Use DC-Straight Polarity (DCEN) for steel and stainless. Use AC for aluminum.

  3. Always use a push technique with the TIG torch

  4. Match the tungsten electrode size with the collet size.

  5. Aluminum - use a pure tungsten, AWS Class EWP (green identifying
    band). Will form a balled-end in AC.

  6. Steel and stainless steel - use a 2% thoriated tungsten, AWS Class
    EWTH-2 (red identifying band). Prepare a pointed-end for DCEN
    welding. (Refer to Diagram 11. Tungsten Preparation)

  7. When welding a fillet, the leg of the weld should be equal to the thickness of the parts welded. (Refer to Diagram 10. Recommended Fillet Weld Thickness).
