ConteC MD

/ Novel contacting technology

/ Two moveable half-shells keep the contact surfaces and the contact forces between the contacting system and the

welding wire exactly in the defined target range. The contact tip abrades uniformly, thereby minimising the adverse,

hard-to-calculate consequences of uneven wear upon the process. The result is constant and unfluctuating contacting,

extremely high process stability and a lower probability of failure due to contacting-faults. With its versatile contact

shells, Contec MD is suitable for all materials and all wire diameters from 0.8 – 1.6 mm.

Process stability

/ Contec ensures unchanging process stability over a long lifespan. It
minimises the downtimes needed for preventive changing of the contact
tip, and the risk of faulty components.

Contact tip in the most negative case

Relative lifespan 100 %

/ The cast of the wire leads to disturbance variables in the contact tip such as abrasion, and the tendency for abraded

particles to burn onto the tube. The contacting points change, resulting in faulty welds and higher outage costs. In contrast

to this, the versatile half-shells in the Contec system keep the contacting points constant even when subject to increasing

wear. The probability of failure is significantly lower.

WE HAVE THREE DIVISIONS AND ONE PASSION: SHIFTING THE LIMITS OF POSSIBILITY.

/ Whether welding technology, photovoltaics or battery charging technology − our goal is clearly defined: to be the innovation leader. With around

3,000 employees worldwide, we shift the limits of what’s possible - our record of over 1,000 granted patents is testimony to this. While others progress
step by step, we innovate in leaps and bounds. Just as we’ve always done. The responsible use of our resources forms the basis of our corporate policy.
