The power source offered by this machine is stronger, more concentrated and produces a more stable arc. Its response is quicker and it can even be adjusted for speciality welding to make the arc softer or harder.

It can weld stainless steel, alloy steel, carbon steel, copper and other colour metal. It can apply to electrodes of different specifications and materials, including acidity and fibre. It can operate at high altitude, the open air and inside and outside environments. It is compact in volume, light in weight, easy to install and operate.

 

Key Features:

  • For repair and maintenance work indoors and outdoors
  • Suitable for stick/electrode welding (MMA welding)
  • Body made of powder coated steel sheet

Mini Arc Inverter Welder

The Latest IGBT Technology

IGBT is a bipolar transistor with an insulated gate electrode. This semi-conducting device is being increasingly used in power electronics because it combines the advantages of two transistor types: the easy controls of the field effect transistor and the fast switching and high breakdown voltage of the bipolar transistor. The IGBT also offers some robustness against short circuits because it limits the electrical continuity.

Featuring Hot Start

Hot Start automatically boosts the tension at the ignition of the arc, this function facilitates the electrical arc ignition. After ignition, the unit automatically returns to the pre-set voltage.

Anti-Stick

This function helps to prevent overheating of the electrode by switching off the welding current when the electrode sticks to the material.

MMA Arc Welding

MMA is electrode welding with a coated electrode.
