This machine is a semi automatic stitchseam welding machine, designed for welding round duct / pipe / drums in large diameter. - details see: https://www.machineto.com/stitch-welder-seam-welder-10141398

I Main features:
1.1 Large diameter range: 100mm~1500mm (5"~59")
1.2 High production efficiency
1.3 Good welding quality because of adopting double-wire technology
1.4 Reasonable structure and simple maintenance: compact structure; welding electrodes
and main driving mechanism are of simple assembly.
1.5 Fast change welding pipe diameter
1.6 PLC & inverter control the welding speed and stitch welding pitch

II Technical data
2.1 Diameter range: 100-1500mm (5 to 59")
2.2 Length of pipe/tube/duct/drum: 50-1000mm (2 to 40")
2.3 Thickness of material: 0.4-1.2mm (28 to 18ga) **
2.4 Suitable material: galvanized steel, carbon steel, stainless steel
2.4 Welding speed: 4-12m/min (13 to 40ft/min)
2.5 Total power: 55kW, 3 phase, 50Hz, 380V
2.6 Specification of fuse: 3x120A
2.7 Compressed air needed: 0.6MPa (dry, clean)
2.8 Copper wire diameter: 1.8mm-2.0mm, tension strength more than 210MPa, elongation 25%
2.9 Cooling water: 0.4-0.6MPa, 12-15 centigrade, 7L/min, cooling motor power 6kW
