Wire feed setting
This setting adjusts the wire feed speed.

Ground cable and clamp

The ground cable and the clamp are attached to the workpiece to form a closed circuit which allows
the flow of current needed to weld.

Welding Cable and MIG gun/torch

The welding wire is driven through the welding cable and the MIG gun/torch to the workpiece. It is
attached to the drive system and the gun trigger activates the drive motor.

Thermal Indicator

If the duty cycle of the welder kit exceeds the maximum level, the internal temperature of the welder
kit will exceed the allowable operating range, which in turn makes the thermal overload light glow
and the welder kit to be shut down automatically. Allow the welder kit to cool down for 20 minutes
until the thermal overload light turns OFF automatically. The temperature of the welder kit is then
within the allowable operating range.
Power cord
The power cord connects the welder to the 120 V power supply. Connect the 15 A plug into a
120 V/20 A receptacle to supply power to the welder.

Polarity changing

Factory polarity setting (electrode negative) is for flux core welding (no shielding gas is required). In
this process the RED gun lead is connected to negative ("-") polarity terminal and the ground cable
is connected to the positive ("+") terminal.
For MIG welding (solid wire) using shielding gas, the RED gun lead is connected to positive ("+") and
the ground cable is connected to negative ("-").
