Semi-automatic Shear Welder

Main performance features

•  The shears are burrs free since triple blades shearing is adopted.                                 

•  The power (compressed air or hydraulic oil) is available easily.                                  

•  The unique metal strip positioner is equipped for accurate positioning and easy operation.           

•  Operation becomes easy and reliable since the accurate positioning for metal strip is adopted and  the pedal swithes are equipped to control the air cylinder or hydraulic cylinder.

•  Tungsten electrode DC welding/pulse arc welding (or AC/pulse arc welding) is adopted for strip welding to get a smooth welding seam, which needs no grinding. This minimizes the impact force to the machine caused by the high welding ridge when drawing the strips.

•  Quality welding seam is achieved with high strength.                                                        •  The whole welding process is automatically finished by applying PLC and frequency inverter,from torch starting, running, arc ignition, welding current rise, arc stabilization, current drop, arc blowout, to welding torch return and reset.                                                     •  The welding current rises and drops slowly and automatically at the starting end and finishing end to minimize the welding gap at 2 sides of strips.
