TIG Welding:
AC TIG is generally used to weld aluminum and magnesium materials. For the best appearance, highest
quality and leak free welds on aluminum, AC TIG welding is the process of choice. The primary gas used is argon and in some
applications on thick aluminum when additional penetration is needed an argon/helium mixture or pure helium is used. TIG welding
offers the user the greatest amount of flexibility to weld the widest range of material and thickness. AC TIG welding is
also the cleanest weld with no sparks or spatter.
DC TIG is generally used to weld exotic material like stainless steel, nickel alloys, copper, titanium and
critical welds that must be flawless such as aircraft engine parts. The primary gas used is argon and in some applications
an argon/helium mixture or pure helium is used. TIG welding offers the user the greatest amount of flexibility to weld the widest range
of material and thickness and types. DC TIG welding is also the cleanest weld with no sparks or spatter.
