The PowerArc 140ST has been a very good seller, since its introduction. We are adding the PowerArc 160 STH as well. Both are Stick Tig welders. The 160 will have a High Frequency start, along with an available foot pedal and will be dual voltage as well. Rod capability is from 6011-7018, great for around the farm use, or in the shop.
The 140ST are improving with better 110V performance, with higher output, and the amp meter accuracy in 110V has been improved, which was a relatively minor issue before, but has been greatly improved. Internal unit protection has been improved, and heavier relays have been installed, to handle higher amp draws, in low or unstable voltage situations. Work leads on units going out now are 10FT instead of the 6ft ones before.
