TecArc 301 square wave AC/DC TIG welder, this popular range of machines has now been given a new modern cabinet design which can now take the option of the integrated water cooling unit.
This single or 3 phase 300 amp tig welder is suitable for all professional TIG welding applications, it can produce the highest quality welds on a very wide range of ferrous and non ferrous materials. It also has advanced features such as pulse, slope balance, digital read out etc, this machine is not inverter based.

These machines are manufactured with a large copper wound transformer, heavy duty thyristors and other substantial components all assembled into a strong powder coated steel case, this ensures the very best reliability & very long lifespan even in the most demanding environments. We have supplied these models into virtually every type of industry including general fab shops, motor sport, offshore industries, aerospace engineering etc.
