What you'll be running

This posting calls for TIG and Stick work. TIG (GTAW) uses a non-consumable tungsten electrode with filler added by hand, giving the operator the most control of any process. It is slow, demanding, and the standard for stainless, aluminum, and anything where the bead has to look as good as it holds. Stick (SMAW) burns a flux-coated consumable rod and needs no shielding gas, so it works in wind, rain, and on dirty or rusted steel. That tolerance for bad conditions keeps it the default for field, structural, and repair work.
