AC Tig-Sharp Point-2% Thoriated-before & after picsI took these pic's, last week to show-the ability of an inverter to maintaina sharp point on 2% thoriated tungsten on AC--which focuses the arc (and thus the heat), not letting the arc dance around, allowing easy welding in corners, in addition to welding quicker and hotter than the 'normal' method of  using pure tungsten with a nice ball to spread the out the heat, dance all around,consuming more time and gas, with significantly more power required.I'm posting this simply to help illustrate what can be done, not to ignite another great debate over transformers vs. inverters.Setup: T-D 300 GTSW, 150a max, 80 cps, 15% balance, pure Argon, C-K flex loc torch, #7 gas lens, 1/8" 2% thoriated tungsten15 min's. arc-on laterBelow, the work involved welding 4 reinforcement plates to the already repair welded handle. This is an internally dirty casting. A center plate with a hole is added, later; after beveling.This is not a make pretty, job---it's a make stronger job. The initial welds shown get ground, carbide burred, then more welding and fairing from the plates to the casting. Yes, I know there's some 'suck holes'--those get beveled out, etc.Blackbird
