ESAB Welding & Cutting Products has introduced an industrial ready-to-weld GMAW package, the Migmaster® 275. Rated 275 amps at 40 percent duty cycle and 200 amps at continuous 100 percent duty cycle, the machine features DC welding output from 30 to 300 amps with new heavy-plate parameters for 5/8 in. and thicker.
Twenty-four overlapping heat (voltage) steps allow fine-tuning. Flat and slope taps allow further fine-turning of short arc parameters for reduced spatter. A solid-state contactor control provides reliability under repetitive short cycle welds, the company states.
The built-in wire feeder with a pulse width-modulated, solid-state speed control feeds wire from 40 to 750 IPM. Additional features include toolless polarity change, an NAS gun connection with built-in torch wrap, and a built-in spool-on-gun control.
The package includes a power source with built-in wire feeder; factory-installed undercarriage with cylinder rack; GunMaster NAS MIG gun; dual-groove feed roll; flowmeter regulator; and all necessary hoses, cables, and accessories for immediate welding.
