150 A TIG WELDING MACHINE
TIG150i
INTRODUCTION
The TIG150i is a 150A inverter-style AC/DC TIG welder that is used to weld both ferrous
and non-ferrous metals. The inverter technology is a smaller and therefore lighter package
size allows portability when needed or can also be placed onto a cart for traditional use
around the shop. Welding capabilities range from extremely thin up to 1/4" on multiple
passes. The welder features ease-of-use for quick start-up in addition to multiple features
such as upslope, downslope, pulse and frequency adjustment or the most experienced
welder. Applications include automotive repair, collision repair, motorsports, manufacturing,
marine, aviation, agriculture and metal fabrication shops.
