MULTIMIG 621 – Aluminum Welder

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 technology 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 fingertip, thanks to a feeder built into the grip. The very small and lightweight torch (no bulky spool-gun) enables real-time control of the 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 times, 4 times, Spot Time, Pause Time, Inductance, Burn Back, Soft Start etc. It can operate in pulse synergic, synergic, or conventional mode.
