Key Features & Benefits

Multiprocess Welding Capability

Handle a wide range of welding applications with one versatile machine. Switch between MIG, Stick, TIG, pulsed MIG, double pulse MIG and air carbon arc gouging to reduce equipment investment, save floor space and move efficiently between jobs.

Single & Double Pulse Capability

Achieve high-quality weld finishes with the speed and efficiency of MIG welding. Single and double pulse functionality helps produce professional-looking results while improving control and reducing reliance on time-intensive TIG techniques.

Intuitive Digital Interface

Clear digital controls make machine setup straightforward for operators of all skill levels. Simplified adjustments help reduce training time, minimise setup errors and support consistent weld quality across shifts.

100% Duty Cycle at 400A

Designed for demanding industrial workloads, the MP400iP delivers 400A at a rated 100% duty cycle, allowing continuous welding at its rated output under specified conditions without routine cooling interruptions.

Full Synergic Pulse with Presets

Simplify setup with intelligent synergic controls. Select the wire size and shielding gas type, and the machine automatically configures the corresponding welding parameters using pre-programmed combinations.

• Faster machine setup.
• Reduced guesswork when selecting parameters.
• Consistent welding results.
• Less training required for new operators.

Trigger Program Switching

Recall up to four preset welding programs directly from a compatible standard MIG torch trigger. Quickly switch between stored settings to improve productivity when working on complex components and jobs requiring different parameters.

Industrial Durability & Reliability

Miller Robustness

Designed for demanding industrial environments, the MP400iP features an IP23S-tested and approved design to support reliable operation in challenging working conditions.

Fan-On-Demand™ Energy Efficiency

The cooling fan operates only when required, helping reduce noise, energy consumption and the amount of airborne contaminants drawn through the machine.

Wind Tunnel Technology™

Internal airflow is designed to help protect sensitive electrical components and circuit boards from dirt, dust and debris, supporting improved reliability and service life.

Versatility & Practical Design

• Air-Cooled or Water-Cooled Compatibility: Supports upgrading from air cooling to water cooling without modification to the machine or trolley.
• Wire Feeder Suspension Hook & Wheel Kit: Provides additional flexibility and reach when positioning the wire feeder.
• Cable Management System: Helps keep the interconnection cable off the floor for a tidier, more organised work area.
• On-Torch Control Compatibility: Compatible with on-torch adjustment of wire feed speed and voltage.

Push-Pull Compatible

Full push-pull capability provides greater reach, flexibility and convenience for wire feeding applications.

The MigMatic® Push-Pull MIG Gun Kit (Part No. KIT0009) is designed to pair with the MigMatic® MP400iP, helping deliver consistent wire feeding across a wider range of welding applications.
