140A 4-in-1 MMA Welder – Stick and Lift TIG, LED Display

140A 4-in-1 welding machine delivers flexible multi-process capability for DIY repairs, garage fabrication, and outdoor jobs. Switch between Stick (MMA), DC Pulse MMA, DC Pulse TIG, and Lift TIG to match the task, while the clear LED display keeps settings easy to track. Synergic control helps you dial in current faster based on electrode size, reducing guesswork and setup time.

• Switch between MMA, DC Pulse MMA, DC Pulse TIG, and Lift TIG for one-machine versatility.


• Monitor and adjust settings on the LED display for quick, clear control in any workspace.


• Use synergic MMA control to auto-suggest current by electrode diameter for simpler setup.


• Weld carbon steel, stainless steel, copper, and titanium; supports E7018, E6013, E6011 rods.


• Reduce sticking with adjustable hot start plus built-in VRD, overcurrent, overvoltage, overload, and overheat protection.

Designed for practical, everyday welding needs, this compact inverter welder balances portability with the control you want for cleaner arcs and consistent starts. Choose a mode that fits your material and workflow, then fine-tune output on the front panel for repeatable results. Note: TIG capability is built in, but a TIG torch is not included—add a compatible torch if you plan to run TIG. Grab yours today and keep more projects moving.
