Eastwood's TIG 200 welders offers industrial features at DIY prices. TIG welding, also known as GTAW (Gas Tungsten Arc Welding) is ideal for welding aluminum and stainless steel. One of the Eastwood TIG welders is an AC/DC TIG welder that features square-wave inverter technology and can operate on 110vAC or 220vAC. (Also available as a DC-only welder—no aluminum welding.) Whether you want to learn how to TIG weld or are a professional welder, you'll be impressed by the features of our TIG welders. Our best TIG welders are for sale individually, but the AC/DC TIG welding machine is also available for sale in kits for extra value and savings!
