Amico TIG-185 can weld 3/8 In. Steel, Stainless steel, Alloy steel, Mild steel, Nickel alloys, Copper, Brass, Bronze, Cast Iron and Chrome etc. TIG-185 is a rectifier adopting the most advanced inverter technology. welding power source can offer stronger, more concentrated and more stable arc. when stick and work piece get short, its response will be quicker. it means that it is easier to design into welding machine with different dynamic characteristics, and it even can be adjusted for specialty to make arc softer or harder.
