The CWMIG400iJ compact MIG welder combines full power with very smooth arc characteristics. This design is for the user who needs a welder for medium to heavy fabrication work and rural use. Equipped with multi-position voltage switching to allow precise adjustment of welding parameters and has a four-roller drive unit for smooth wire feeding. A high-quality copper wound transformer with a large cooling fan maximizes cooling and mechanical stability. 
 
Nothing but the best, this MIG welder is designed to offer the highest quality welds available from CRUXWELD. It covers an additional 16.5 feet, providing more movement due to the external wire feeder. In addition, the innovative closed system design prevents dust and moisture from contaminating the wire, keeping the weld safe. Using advanced welding technology, this MIG welder is the most powerful in its class. 
 
The CWMIG400iJ MIG welding machine stands alone for the most demanding jobs in heavy fabrication, mining, pipelines, oil and gas, civil construction, shipbuilding, defense, steel structure installation, and maintenance.
