When compared to conventional nozzles, the Contec MD contacting system allows the user to prolong the service life of their welding torch several times over. This applies to the joining of both aluminium and steel. With conventional automated welding systems, wear variables such as abrasion and spatter damage, are caused by the straightening of the wire in the contact tip. This causes the contacting points to change, resulting in faulty weld beads and higher outage costs. With Contec MD, two movable split tips keep the contacting surfaces and contact forces between the contacting system and the welding wire exactly in the defined target range – even in the face of increasing wear. This results in even wear of the contact tip, minimizing numerous adverse effects on the process. The user enjoys steady and even contact, high process stability and a lower probability of failure due to poor contact. Contec MD is suitable for all materials and wire diameters from 0.8 to 1.6 mm.
