TIG welding machines come in two forms - DC only and AC/DC. The DC only machines are ideal for mild steel and stainless steel. We prefer to sell pulsed versions of these machines because it makes welding so much easier and we believe that by going for better quality you will be a happier customer. 

The AC/DC machines are what you should be looking for if you are planning to ever TIG weld aluminium. We only sell good quality units and as such any TIG welder from Noz-Alls you can trust to give you a long service life.
