Product Code
A heavy duty range of MIG welding machines designed for all industrial welding applications.
These machines are designed and manufactured in Great Britain using high quality components to industrial standards. This range of machines offer the user the very best welding performance with minimal spatter and a soft stable arc throughout the range. At the heart of every machine is a large copper wound transformer & other heavy duty components all constructed in a robust powder coated steel case, this ensures these are probably the most solid & reliable range of compact MIGs available, with thousands sold over the last few years.
We guarantee these machines will have the lowest long term maintenance costs of any similar machine in the industry & we have the best long term back up with all parts available for a minimum of 20 years.
