The HYMMA-121 is a lightweight and incredibly versatile single phase ARC/MMA welder from Hyundai that can be powered by a standard UK 3-pin 13amp plug.

Weighing only 4.5kg, the HYMMA-121 is easy to carry around thanks to its adjustable harness and lightweight pressed steel case with powder coated finish for extra corrosion resistance. Accessories include electrode holder with 2m cable, earth clamp with 1.5m cable and wire brush making the HYMMA-121 extremely cost effective.

The HYMMA-121 ARC welder features a stepless regulator for infinite variable control of the welding current with a low current facility for effective welding of thinner materials. The welding (output) current of the HYMMA-121 can be regulated within the range of 10-120 Ampere making the HYMMA-121 adjustable to suit welding different materials and thicknesses of steel. Fitted with a LCD digital display the HYMMA-121 features auto hot start and anti stick technology.

The inverter technology used within the Hyundai welders has certain advantages compared to more traditional transformer welders. The inverter type welders are usually lighter, more cost effective and usually require less input power for a comparable output. This makes them more cost effective not only to purchase, but also to run.

Fitted with thermal overload protection to ensure maximum durability. Suitable for welding steel, stainless steel, copper, nickel, titanium and their alloys.

Suitable for farmers, home mechanics, mobile technicians and DIY enthusiasts the HYMMA-121 is a good all rounder for welding with rods of 2.5mm and up to 3.2mm. The HYMMA-121 features high frequency starts allowing for smooth arc strikes.

With low service and maintenance requirements, the HYMMA-121 is incredibly easy to use and maintain, and has full Hyundai UK parts back up.

In the box: Electrode holder with 2m cable, Earth clamp with 1.5m cable & Wire brush.

Know your welder:

(MMA) Manual Metal Arc - Metal Arc Welding (MMA) or (MMAW) Manual Metal Arc Welding is flux shielded arc welding or informally known as stick welding, is a manual arc welding process that uses a consumable electrode covered with a flux to lay the weld.

(TIG) Tungsten Inert Gas - Tungsten Inert Gas Welding (TIG) or (GTAW) Gas Tungsten Arc Welding is an arc welding process that uses a non-consumable tungsten electrode to produce the weld.

(MIG) Metal Inert Gas - Metal Inert Gas Welding (MIG), (GMAW) Gas Metal Arc Welding or (MAG) Metal Active Gas is a welding process in which an electric arc forms between a consumable wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to melt and join.

Covered by Hyundai UK 2 year warranty.
