When the job can’t come to you, the MPi 220P contains all you need to MIG weld in one small lightweight package. With the flip of a switch, all processes are available to meet the application at hand.

Durable Cast Aluminium Feedhead

Incorporates dual-groove quick-change drive roll and spring-loaded tension arm with calibrated tension knob, all designed to make set up easier and faster.

Large Graphical Display

Guides users through process and parameter setup with ease and high visibility.

Excellent Arc Characteristics

The MPi 220P offers positive arc starts and an extremely stable arc with minimal spatter on both mixed gases and straight CO2. Easy access to output studs provides convenient polarity changeover when changing from solid or flux cored wires. 

Selectable Trigger Configuration

Allows the operator to choose standard or 2T trigger method.

Built-in Run-In/Crater/Burnback Function for MIG

Helps provide better arc starts and reduces craters.

Adaptive Hot Start™

Increases the output Amperage at the start of a weld if necessary, eliminating electrode sticking.

Thermal Overload Protection

Shuts down unit and activates over temperature light if airflow is blocked or duty cycle is exceeded. Automatically resets when fault is corrected and unit cools.

Built-in Upslope/Downslope Function

For TIG. Helps provide better arc starts and reduces craters.

Synergic Welding Mode

Offers the simplicity of single knob control. The machine will select the correct Voltage and Amperage based on the wire feed speed (WFS) set by the operator.

Full Weld Process Capability

MIG, Pulse MIG, Stick and TIG are available to meet the demand of current applications.

Adjustable Preflow & Postflow

Gives operator better control of the gas parameters affecting weld zone.
