Buying an inverter TIG welder from Noz-Alls is easy, all you have to do is click the machine type required and decide on the welder you require. If you are local then you can test a TIG welder in our demo area. Remember if you are after a machine to TIG weld aluminium then you will need an AC/DC machine, stainless and mild steel on the other hand can be welded in DC. For this reason the TIG welding machines category has been split into two sections.
