You can also tweak voltage ±3V manually with the adjustment knob, giving you the flexibility to fine-tune your welds whether you’re inexperienced or experienced.

Power and input flexibility

The automatic 110/220V dual-voltage detection is a strong convenience feature for DIYers and contractors who move between job sites with different power availability. This flexibility means you won’t need a heavy transformer or dedicated 220V outlet every time you want to weld thicker material.

Performance on 110V vs 220V

On 110V you’ll be limited to lower maximum output and may need thinner material or multiple passes for thicker joints. When you switch to 220V, you unlock closer to the 145A capability, allowing deeper penetration and cleaner welds on thicker stock. You’ll need to be realistic about throughput on household circuits.

Welding modes — what to expect

The 3-in-1 capability is the main selling point: gasless flux-core MIG, Lift TIG, and stick welding give you versatility for different materials and conditions. If you focus primarily on one process, this machine still gives you the option to experiment or handle other tasks without buying a second machine.

Gasless flux-cored MIG welding

You’ll find flux-core welding great for outdoor work and jobs where shielding gas is impractical. The machine supports common flux-cored wire diameters and gives decent arc stability for carbon steel and stainless in many applications.

Lift TIG capability

Lift TIG lets you start TIG arcs without high-frequency start systems, useful when you want cleaner TIG-style welds on thin materials. Because the lift TIG torch is not included, you will need to purchase a compatible torch and set up argon gas if you want to TIG weld properly.

Stick welding

Stick mode provides versatility for maintenance, repair, and outdoor welds where flux or gas is less convenient. You’ll appreciate the IGBT inverter technology that helps keep stick arcs stable within the current range.

Wire feed and consumables

The integrated wire feed mechanism and included rollers for 0.030″/0.035″ are convenient for getting started. You’ll benefit from the included contact tips and flux-cored spool so you can begin welding without sourcing many parts immediately.

Wire compatibility and changeover

Changing wire sizes and rollers is straightforward, and the machine supports the common 0.030″, 0.035″, and 0.040″ flux-cored wires. You should keep spare contact tips and rollers for the wire diameters you use most to minimize downtime.
