Overview

Thyristorised MIG 400 for heavy-duty MIG/MAG work

The CRUXWELD Thyristorised MIG 400 (CWM-MIG400T) is a thyristor MIG welding machine for a 415 V three-phase supply. It delivers 60–400 A at a rated output voltage of 28 V and feeds 0.8, 1.0, 1.2 and 1.6 mm wire, which makes it a dependable choice for semi-automatic MIG/MAG welding on structural and machine-building jobs.

The thyristor power supply works with a purpose-designed transformer for a quick response and strong arc dynamics. Crater voltage and crater current are set with knobs on the front panel, so the end of every weld fills properly. Power factor is 0.93 at a rated input of 20 kVA.

03Frequently asked questions

What is a thyristor MIG welding machine?

It is a MIG welder whose output is controlled by thyristors on the secondary of a welding transformer. Thyristor machines are known for a robust build and a steady arc on heavy work.

Can the MIG 400T be used for automated welding?

Yes. It is designed for both hand-held semi-automatic and automated welding applications. Talk to our technical team about matching it to your carriage or fixture.

What power supply does it need?

415 V three-phase (±10%), 50/60 Hz, with a rated input of 20 kVA.
