Cantilever Type H Beam Welding Machine

The working principle of the double column welding machine is similar with gantry-type welding machine. The difference is that, for gantry welding machine, the welding is accomplished between two rails; for double column welding machine, the welding is accomplished outside the rails. It can weld the H-beam which is higher than 1.5m, no limit for beam height. When it is single arc single wire welding , the welding power can be settled on the machine trolley.
