Electrical resistance welder with two current carrying electrodes - where the lower electrode has a vertically variable position, and can be automated

摘要

The welding machine comprises a fixed structure supporting two vertically spaced current carrying electrodes, the lower of the two electrodes being movable vertically and cooperating with control means regulating its position the control means being adapted for connection to programmable devices to control the electrode automatically and vary the vertical movement according to requirements. The machine is capable of a multi-faceted work schedule because it is adaptable to specific requirements and enables welding costs, on both a large and small scale, to be reduced.
