Description
MultiQuip GAW180HEA Overview
The MultiQuip GAW180HEA is a portable welder and generator that combines 50 to 180 amps of DC stick welding output with 3,000 watts of single-phase AC power. A Honda GX340 gasoline engine rated at 10.7 HP drives a compact, maintenance-free permanent magnet alternator, a design that cuts weight without compromising performance and makes the unit easier to take to remote job sites or carry on a service truck. Both electric and recoil starting are provided, and an electric start battery comes with the machine.
Inverter technology gives precise sine-wave control, delivering clean, stable AC and DC output that is compatible with sensitive electronics. The unit can weld and supply AC power at the same time, so lights, grinders and other tools keep running while you work. Heavy welding at 180 amps does reduce the AC wattage left for auxiliary tools, so it pays to calculate loads carefully when doing both. Arc Force Control fine-tunes DC current during low-voltage, short-arc conditions to keep the electrode from sticking and help produce a smooth bead, and it also helps steady the arc when you work close to the duty cycle limit. A full panel of GFCI-protected outlets meets OSHA and NEC standards. Welding leads and cables are sold separately.

Frequently asked questions
What welding output does the MultiQuip GAW180HEA provide?
The GAW180HEA delivers 50 to 180 amps of DC stick welding output at 26.8 V, with a 50% duty cycle at 180 amps. Arc Force Control fine-tunes DC current during short-arc conditions to keep the electrode from sticking and help produce a smooth bead.
Can the GAW180HEA weld and power tools at the same time?
Yes. It supplies 3,000 watts of single-phase AC power at 120V / 25A while you weld, so lights and grinders keep running. Heavy welding at 180 amps reduces the AC wattage left for auxiliary tools, so loads should be calculated carefully when doing both.
What engine powers the GAW180HEA and how does it start?
A Honda GX340 gasoline engine rated at 10.7 HP (8.0 kW) at 3600 RPM drives a compact, maintenance-free permanent magnet alternator. Both electric and recoil starting are provided, and an electric start battery comes with the machine.
How long does the GAW180HEA run on a tank of fuel?
The listing does not state a run time in hours. It gives a fuel tank capacity of 3.7 gallons and fuel consumption of 0.93 GPH at rated load, so actual run time depends on how hard the unit is welding and powering tools.
Is the output safe for electronics, and what else should buyers know?
Inverter technology gives sine-wave control for clean, stable AC and DC output that is compatible with sensitive electronics, and the GFCI-protected outlets meet OSHA and NEC standards. Welding leads and cables are sold separately. The unit weighs 246 lbs and measures 27.5 x 22 x 23.8 inches.
