0558102218 - ESAB MigMaster 275 MIG Welder Package with Tweco 350A Gun

Industrial Grade MIG Welding Package

The ESAB MigMaster 275 (SKU: 0558102218) is a comprehensive MIG welding system designed for light to medium industrial fabrication. This package is engineered to deliver high-performance welding characteristics with the reliability expected from ESAB's legacy transformer-rectifier technology. The unit provides a substantial output range of 30 to 275 Amps, making it capable of welding thin gauge sheet metal as well as heavier plate up to 1/2 inch thick in a single pass.

At the core of this system is a robust power source boasting a 50% duty cycle at 250 Amps (40% at 275 Amps), ensuring consistent performance during extended production runs. The machine features 24 overlapping voltage steps, allowing operators to fine-tune the arc voltage for optimal bead profile and penetration. The built-in wire feeder is designed for durability, featuring a heavy-duty drive mechanism that ensures consistent wire feeding speeds from 50 to 800 IPM.

This specific package distinguishes itself with the inclusion of the Tweco Spray Master 350 MIG gun. Known for its ergonomic handle and durable consumables, the Tweco gun enhances operator comfort and weld quality. The system also includes digital volt and amp meters, which are essential for procedure compliance and repeatability in industrial environments. Additional features include adjustable burnback control to prevent wire sticking in the puddle and a spot weld timer for consistent tacking or spot welding applications.

The unit comes factory-equipped with a low-profile cylinder rack and running gear, providing excellent stability and mobility within the workshop. It supports a wide range of wire diameters from 0.023" (0.6mm) to 0.045" (1.2mm) and is spool gun ready, allowing for easy expansion into aluminum welding applications with the addition of a compatible spool gun.
