seam welding machine, voltage : 380/220/440V, duty cycle: 50%, Model No: 35/50/75/700/150KVA - details see: https://www.machineto.com/rolling-seam-welding-machine-rolling-seam-welder-resistance-seam-welder-10141607

Rolling Seam Welding Machine, rolling seam Welder,resistance seam welder

Jaws holding parts to be welded are pneumatically and hydraulically controlled.
First part of the cycle removes oxides and equalizes surface condition by passing pre-heat current (parts may be oscillating).
Second part of the cycle upsets the parts with a great force, squeezing imperfect metal outside of the joint, creating very strong bond.

This equipment is used to weld wide range of parts from automotive rims to knife and spoon handles.

Pre-heat, flashing and upset forces are controlled by combination of electro-mechanical, pneumatic and hydraulic devices for precise control of the process.

Microprocessor control and multi-tap arrangement in transformers allows selecting precise parameters for welding various parts

Mainfeatures of the machine

(1) Novel structure, special design, good rigidity.

(2) Adopt the cylinder pressurizing, easy and exact to adjust.

(3) Adopt the microcomputer crosscurrent control, the welding time and current can be exact to controled.

(4) Welder has two kinds of welding method,namely vertical / horizontal
