This is a mid/late 1980's Miller Syncrowave 500 Amp TIG welder. Model 500S with SP-4 programmer (hi freq pulse). Works great. Includes foot control and HW-12 water cooled torch and Miller Chillmate chiller (not pictured). Does NOT include tank or regulator. SINGLE PHASE! Wired for 440/480V. is easily rewired for 220V single phase. The beauty of these older welders is that they AREN'T all digital with microprocessor controls. So, if it ever has a problem, the board can be repaired rather than replaced. Includes Operators/owners manual for both the welder and programmer which includes all electrical schematics. New price for a comparable machine is body parts you wouldn't want to lose :) If you need a serious TIG machine, this is it. $2500 + tax OBO. DELIVERED to your garage or shop in the Albuquerque area. Weighs about 500 lb. Shipping available to anywhere in the Continental US.
