  • Tig welding aluminum

    I have a Hobart Tigmate & it arc welds, tig welds stainless & regular steel but I can't get aluminum hot enough to puddle. I bought a new torch head, changed tungsten, collet & tank but no change. I can't get the tungsten to ball up on the end either. I have even tried to tig 1/16" aluminum but doesn't seem to work. Tungsten gets white hot but won't get the material hot enough. Any ideas?

    Amperage setting? Tungsten size? Oxide coating still on aluminum?

      What is your polarity for each thing you are doing?

      Have to TIG welded successfully with other equipment that you set up yourself?

      What is your level of experience?
