Mig / Mag Welders

Mig welding also known as Gas Metal Arc Welding (GMAW) has been around since the 1940’s. It incorporates the use of a inert gas to shield the arc of electricity used to fuse the metals being combine. Chief Elektron Fusion Technologies welders use various technology to achieve a better looking high performance weld.

The new generation vehicles being manufactured today use a mix of different materials, which require different joining techniques. The Chief’s MIG?MAG welders all use inverter-based power sources that can meet all the technical specifications provided by the car manufacturers.


MultiMig-621MULTIMIG 621

The 621 delivers high current output with Three Phase supply voltage

Double Pulse feature – mechanically and electrically controls the welding parameters to make aluminum welding easier and for increased confidence.

  • Synergic pulsed technolgy is required by most OEMs for aluminum welding. Includes a complete set of synergic programs in memory for brazing, welding and aluminum wire.
  • Inverter technology enables precision electronic control of output power for better quality welds.
  • GREEN technology – Integrated Power Factor Correction (PFC) technology reduces input power by avoiding energy waste found in most electronic-based equipment and ultimately reduces operating costs. High Harmonic Distortion is hard on the power grid and contains non-working energy, which is costly & environmentally wasteful.
  • Two types of torches can be used with MultiMig power source – a standard MIG torch or the unique push-pull torch. The Chief Elektron Fusion Technologies push-pull system torch has an up-down digital current adjust at your finger tip, thanks to a feeder built into the grip. The very small and light weight torch (no bulky spool-gun) enables real-time control of welding process by control of the wire feed speed and current level. The push-pull system corrects many of the problems encountered when feeding and welding soft aluminum wire, down to 0.6mm.
  • Many programmable options are available to customize the unit operation to meet most working conditions. Options include: Arc Length, 2 time, 4 time, Spot Time, Pause Time, Inductance, Burn Back, Soft Start etc. Can operate in pulse synergic, synergic, or conventional mode.

The Chief MIG/MAG welders provide a series of synergic programs specially prepared for the filler wires to be used in Steel (mild & stainless) and Aluminum welding or for galvanized sheet metal and High-strength steel brazing, such as CuSi3, AlBz8 (CuAl8). Chief welders come with a very large set of synergic programs loaded in the machine.

The synergic program is formed by a series of points that relate voltage and current (wire speed). The programs stored in the welder provide a valuable aid in establishing the ideal parameters to perform the work. The operator simply selects a synergic program, according to the wire used and recommended shelding gas, and the thinkness of the workpiece to set the base parameters. He can then adjust the parameters as needed to match the specific application and his personal way of welding.
