Narrow gap welding - Revolution for thick plate welding

MIG/MAG process with narrow gap technology for efficient thick plate welding
Narrow Gap Weld is suitable for plates with a material thickness of more than 35 mm. The narrow gap blade is the heart of narrow gap welding. The oscillating wire guarantees optimum side wall joints. The narrow gap blade is able to enter into gaps which are up to 300 mm deep, but only 20 mm wide. It guides wire, shielding gas and coolant. With the narrow gap technology you just start saving during the prefabrication as there is no need of  a weld seam preparation. You reduce the machine running time and the need of welding wire. You need less shielding gas. And you save energy. Do you wish to reduce your production costs for thick plates and to increase the quality at the same time? Then rely on Narrow Gap Weld by CLOOS!
