WELDING VALUE

/ Battery Charging Systems / Welding Technology / Solar Electronics

/ Time and again, our revolutionary ideas take the welding community by surprise.

As they did with Cold Metal Transfer (CMT), a weld process that really is »cold«

compared to conventional MIG/MAG welding. And that ensures a stable arc and exact

process-control. CMT lets you weld joins between aluminium and steel, and light-

gauge sheets from only 0.3 mm (0.01 in) thick. Other advantages: minimal spattering,

excellent gap bridgeability, 100% reproducibility of results. Want to know more?

Small holes, fine inside and outside contours:

the precision of Contour Cut revolutionises

plasma cutting of mild steel.

A new technology without additional

costs and components!

Because Contour Cut is integrated as

standard in all HiFocus systems.
