Multifunctional welding system MIDI MIG 300/800 AC/DC G W

Low-spatter MIG / MAG AC impulse welding with converter

The enhanced AC pulse technology enables a new dimension of arc welding of heat-sensitive materials such as aluminum, stainless steel and other heat sensitive alloys.

The MIG AC process regulates the separation of penetration bead by switching over perodically the negative and positive polarity and at low or high energy phases. During the positive energy phase the bead is removed from the wire end that was preheated before in the negative energy phase and is transferred to the workpiece without spatter. Additionally, the MIDI MIG 300 AC/DC machines offer all MIDI MIG DC programs with the same weld or braze characteristics!

The machines of the MIDI generation are equipped with a database that practically includes all welding properties for all current welding methods and types of processes including all necessary welding parameters. Via single-knob control the user can set his machine on specific tasks within a short time.
