Multimig 721 welder

Multimig 721 Welder


The Multimig 721 Welder 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 control of output power for better welds.

T-Link Technology option – delivers superior eye protection to the welder by darkening the view-screen filter prior to the weld flash, through continuous Bluetooth® communication between the special T-Link filter on the mask and the torch trigger. The filter can also provide normal auto-darkening function that is triggered from the light of the welding arc.

Two types of torches can be used – a standard MIG torch, set up for Aluminum or Brazing or the unique push-pull torch. The 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.
