The METAL MAN MIG 180DVT is a Dual Voltage, portable DC wire feed welder capable of welding with solid wire (with shielding gas) or flux core wire. This unit is capable of welding 5/16 steel in a single pass when operating on 230-Volt power. Use the included 120-Volt adapter cord to run this unit off 120-Volt AC power with a single pass capacity of 3/16. It uses leading edge Inverter Technology to provide high quality welds that are crisp, clean and consistent with plenty of power and will impress the most experienced of welders. It features infinite wire feed speed control and voltage control, giving you total control to tune in the arc you want. The MIG 180DVT also features a cooling fan and thermal overload protection to help protect your investment. The Inverter Technology is evident from the moment you take this unit out of the box. 1 of the many advantages of inverter technology is creating more welding power from a smaller transformer. A smaller transformer means lower overall weight. The METAL MAN MIG 180DVT is perfect for use when welding materials from 24-Gauge to 5/16 and is ideal for the home hobbyist, auto repair, farm and ranch and light industrial applications.
