DESCRIPTION
The Metal Man MIG 140i is a portable DC wire feed welder capable of welding with solid wire (with
shielding gas) or flux core wire. 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 is powered by AC single phase 120V (110-120V), 60HZ/20amp with time
delayed fuse or circuit breaker. It features infinite wire feed speed control and voltage control giving
you total control to tune in the arc you want. The MIG 140i 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. One of the many advantages of inverter technology is
creating more welding power from a smaller transformer. A smaller transformer means lower overall
weight. The MIG 140i is ideal for use when welding materials from 24 gauge to 3/16” and is ideal for
the home hobbyist, auto repair, farm and ranch and light industrial applications.
Power Indicator
When the unit is plugged in and the power switch on the back panel is in the “On” position, the
power indicator light will come on indicating power has been applied to the unit.
Thermal Indicator
If the duty cycle of the welder is exceeded the internal temperature will exceed safe temperatures
and the machine will shut down. The Thermal overload light will come on indicating this. Leave the
unit on and allow 15 minutes for cool down before the light will go off and the temperature to fall into
an allowable operating range.
Voltage Control
The output voltage control is on the front panel of machine. Refer to the “set up” chart inside the
wire feed compartment for initial adjustment settings.
Ground Cable and Clamp
The ground cable and clamp are attached to the work piece to complete the circuit allowing the flow
of current needed to weld.
