185 AMP PULSE MIG WELDER
MIG185i
The MIG185i Pulse is a 230VAC single-phase synergic inverter power source for MIG welding. This
versatile power source is suitable for various applications from general repairs to speci c material
types used in the body shop industry. Welds a variety of material types and thicknesses such as
steel, stainless-steel, aluminum, high strength and boron steels. Preset synergic curves automati-
cally provide proper settings for individual situations and reduce set up times.
