Both spot and seam welding machines consist of a bed frame a transformer and a pressure mechanism with an interlocked switch.
Spot welding machine parts name.
Welding machines are used to permanently connect metal pieces with heat generated from electrical energy.
Electrode cable the function electrode cable connects the current from welding machine to electrode which we use to weld the base metal.
This characteristic allows the welding of plates with some degree of oxide or protection covering.
The digital control allows the parameters adjustment in a simple way with the possibility of effectuating welding cycles with one or two current impulses.
Due to the skills and acquaintance of experts we are extremely praised for offering a superior quality of resistance welding tip adapters to our valuable customers.

Each sheet is of 3mm thick.
Spot welding or resistance spot welding is a type of electric resistance welding used to weld various sheet metal products through a process in which contacting metal surface points are joined by the heat obtained from resistance to electric current.
The metal sheets can be protected by a pair of electrodes by passing the current through the sheets.
The process uses two shaped copper alloy electrodes to concentrate welding current into a small spot and to simultaneously clamp the sheets.

The spot welding machines of the digital series are electronically controlled by thyristors.
This welding machine is used to join the overlap steel sheets.
It is not suitable for site and field work and is the best one to repair the damaged parts.
Spot welding adaptors are made up of cucr1zr and becu copper.
They are available in a variety of sizes and output voltages from a small hobby model with an 80 amp output to an industrial model with a 12 000 amp output for spot welding.
In addition a seam welding machine incorporates a roller electrode drive system.
