Robust For Advanced Welding

Auto-pulse technology for advanced pulse welding of aluminum. Designed for all materials and individual welding applications including high strength steel. Exceptional 4-wheel wire feed system provides a smooth, reliable wire feed even on softer wires such as aluminum or MIG brazing.

Single Torch Simplicity

With one torch, the AUTOMIG 273i offers quick and easy welding through a fully digital interface. Simply switch on – press the button – and weld!

Choose Your Power

The AUTOMIG 273i Pulse Boost offers synergic pre-set welding programs and automated functions. The welder is capable of operating on single or three phase power.

Extend your reach with the MIG-A Twist® welding torch

CMI3000II comes with the MIG-A Twist torch. The unique, rotatable swan neck of the MIG-A Twist allows access to hard-to-reach places. It is possible to mount different modules on top of the torch for adjustment of the most important welding parameters.
