Portable ARC Welder for DIY and Home Repair

This portable handheld welding machine delivers 20 to 120 Amps output with five-level current adjustment for precise control. It operates on 110V input and uses IGBT inverter technology for a stable arc with minimal spatter. The unit suits welding iron and steel up to 0.12 inch thickness and fits 1.6 to 3.2 mm rods.

Bundled Safety Gear and Consumables Included

The package adds a folding welding helmet, a pair of welding gloves, a welding brush and a 1.5 m ground wire so you can start work immediately. Ten 2.5 mm welding rods and a cloth storage bag are also supplied for convenience and portability. Overheat protection and hot start functions further support reliable operation.

30% Duty Cycle at 40°C Defines Continuous Use

At 40°C ambient temperature the welder maintains a 30% duty cycle, meaning it can weld for three minutes out of every ten before thermal protection pauses output. This cycle suits intermittent DIY tasks but limits long, continuous beads on thicker workpieces. Buyers needing sustained high-amperage runs should note this constraint.

Questions about this item

How often will the thermal-overload protection trip on the IGBT inverter if I run the welder continuously at 120 A?

The 30 % duty cycle at 40 °C means you can weld for about three minutes at 120 A before the overheat protection pauses output; let it cool for seven minutes then resume.

What is the maximum welding current the 110 V supply can sustain before the 4.6 KVA input limit is reached?

At 110 V the 4.6 KVA rating supports the full 120 A output range; the machine is designed to deliver 20 – 120 A within that input capacity.

How loud is the cooling fan and how hot does the case get during an all-day repair session with the 1.5 m ground lead?

The IGBT inverter runs a compact fan that stays audible but not intrusive; the chassis warms to the touch after repeated 30 % duty-cycle intervals but the overheat protection prevents excessive surface temperature.
