Three Phase MIG Welders

The SWP MIG 420S + WF400 is a robust three phase machine ideally suited to medium and heavy fabrication and requires only a 20A fuse.
Its full size cabinet can accept full size gas cylinders and its large diameter wheels means it can be moved from job to job with little risk of toppling.

The WF400 wire feeder features SWPs renowned all-geared drive system which will reduces the risk of wire slip making welds uniform.
With its 5 metre interconnection and 4 metre welding torch you have a large working radius of 9 metres. The unit is also
suitable for use with spool-on gun and push-pull gun which increases the working radius up to 13 metres.

The ability to take larger diameter wire than lower power units in the range means it can also weld thicker
plate, and its 21 switch settings allows for fine tuning of the output power.
