Range of M pneumatic and mechanical machines Glossary: WCC: Welding Cabinet Controller EL: Effective Length ED: Effective Depth SS: Single Stroke cylinder DS: Double Stroke cylinder Manual adjustment: Adjustment is performed by a pressure regulator which determines the compressed air supply of the cylinder in order to obtain the best clamping force. Electronic adjustment: The adjustment of the welding force of the cylinder is controlled by a proportional valve. Pressure program: This device allows the pressure to be varied during the force, for example, to reduce it when welding or to...

ARO, world leader in rsistance welding, offers innumerable solutions for spot or projection welding applications, within the 50% of 30 kVA and 50 kVA power ranges. This new range of M machines, completely updated and redesigned, is structured around a single frame, with a choice of 2 pneumatic cylinders, 2 transformers and a range of 6 welding cabinet controllers (WCC). The user therefore has access to a wide range of possibilities to control better the welding current and the clamping force. The pneumatic M sries is equipped in standard version with a wide diversity of equipment such as:...
