Migatronic cable assembly for Automig

The Automig series was created with one aim: uncompromising quality in car body work. The built in synergic programs are a digital knowledge base with precisely defined welding parameters for the specific materials used in vehicles. They cover HSS and UHSS steels, various grades of aluminium and wires for MIG brazing. The welder only selects the material, the thickness and the gas type, and the machine sets the optimum voltage, wire feed speed and arc dynamics by itself. That removes time consuming trials and gives repeatable results in line with OEM requirements.

MIG brazing is a key process in modern body repair, above all when joining thin galvanised sheets of high strength steel. Automig technology places the bead precisely at a much lower heat input than traditional MIG/MAG welding. That protects the anticorrosion zinc layer in the heat affected zone, keeps it from burning off and preserves the structural integrity of the part. The process also minimises thermal distortion, which shortens the time needed for finishing work and keeps the original mechanical properties of the joined materials.

Pulse and double pulse welding are needed for materials sensitive to heat, such as aluminium and stainless steel. A single pulse allows precise control of the weld pool, which gives spatter free welding and sound fusion even in constrained positions. Double pulse goes a step further and modulates the welding current at two frequencies. The result is a bead with a perfect look, close to a TIG ripple, at the speed of the MIG/MAG process. It is the right answer for welding visible body panels, where appearance counts as much as strength.

Depending on the model, the Automig platform offers a Duo or Trio configuration and allows two or three welding torches to be connected to one power source. Each torch can be set up with a different wire and gas, for example for steel, for brazing and for aluminium. The welder switches between processes with a single button on the torch, with no need to re-equip the machine. This function cuts downtime sharply and raises output in a workshop that often handles different materials within one repair. It optimises time and operating costs directly.

Intelligent Gas Control (IGC®) is a smart system for optimising shielding gas consumption. Traditional systems deliver a fixed, predefined amount of gas, which often leads to waste, above all at the start and at the end of a weld. IGC® monitors the welding process dynamically and matches the gas flow to what the arc needs. It gives sound protection of the weld pool while cutting gas consumption by up to 50%. For a company that means measurable savings on consumables and better weld quality through less porosity.
