I want to do some Tig Welding, do I need a DC or AC/DC tig welder?
 
There are two types of TIG welder available

A DC TIG Welder like our TIG200PDC which allows you to weld all steel metals (mild, stainless etc)

If you want to weld aluminium & its alloys you will need an AC/DC TIG welder like our TIG201 This allows you to weld in AC (aluminium and its alloys) & DC (Steel, Mild, stainless etc)
