Bestarc 145A MIG Welder | 4-in-1 Gas/Flux Core MIG, TIG & Stick | 110/220V IGBT Inverter

Versatile welding power in a portable package

The Bestarc MIG145 is a compact 145-amp welder that blends MIG, flux-core MIG, Lift TIG, and Stick welding into one capable tool. Built on an IGBT inverter with synergic control, it takes the guesswork out of setup and delivers consistent results across metals and thicknesses.

Synergic control automatically matches the recommended voltage and wire feed speed (current), while you can fine-tune the voltage within a +/- 3-volt range to suit your project and environment. This makes it approachable for beginners and reliable for seasoned pros.

Four welding modes, one flexible machine

In MIG mode you can weld solid ER70S-6 wire for clean, precise beads on carbon or stainless steel. The gasless flux-core option lets you weld outdoors or in breezy spaces without a shielding gas bottle. Lift TIG adds light steel or aluminum with careful control, and Stick lets you tackle thicker sections or rusty metals where a robust arc is helpful.

• Gasless flux-core MIG supports stable welding in windy conditions
• Solid MIG creates neat beads on stainless or carbon steel
• Lift TIG enables precise arc control for thin materials
• Stick welding expands capability for thicker sections

Dual-voltage convenience and portability

The MIG145 automatically identifies 110V or 220V input and displays status on a large LED screen, removing guesswork at the job site. Weighing only 13.7 pounds, it travels with a shoulder strap for outdoor projects or shop work.

• Seamless switching between 110V and 220V for different power environments
• Light enough to carry to the driveway, garage, or job site
