4-in-1 TIG Welder

The VEVOR 140A unit combines DC Pulse TIG, DC Pulse MMA, Lift TIG and MMA/Stick modes in one machine. It runs on 110V and 220V supplies, making it suitable for home DIY, garage work, outdoor repairs and farm equipment maintenance. The IGBT inverter design keeps the package compact at 310 x 135 x 270 mm.

Synergic Control and Accessories

A large LED display shows all parameters so you can monitor settings at a glance. Synergic control automatically suggests current and wire feed speed based on wire diameter and gas type, helping both beginners and experienced users. The box includes a ground clamp, electrode holder, welding brush and conversion plug for immediate use.

Duty Cycle and Materials

The welder delivers a 20 % load ratio at 40 °C ambient temperature. It handles carbon steel, copper, stainless steel and titanium up to 6 mm thickness. Weighing 5.45 kg with a plastic shell and cold-rolled steel frame, it is portable enough for site work while the inverter topology limits power draw during normal operation.

Questions about this item

What duty cycle does the welder reach at 140 A in a 40 °C workshop?

The unit is rated at 20 % load ratio at 40 °C ambient temperature, so it can sustain full current for two minutes out of every ten before thermal protection trips.

How much fan noise and heat should I expect during an all-day fabrication session?

The IGBT inverter runs cooler than transformer units, but at continuous output the internal fan will run steadily and the steel chassis becomes warm to the touch after prolonged use.

Which gas regulator and tungsten electrodes do I need before I can start DC pulse TIG welding?

You must supply your own argon regulator, flow meter, and suitable tungsten electrodes; the box includes only the power source, ground clamp, electrode holder, brush and conversion plug.
