Welding Machine Control Circuit

When the sb1 button is pressed the output is activated during the set time.

Welding machine control circuit.

An ac or dc power source fitted with whatever controls may be needed is connected by a work cable to the workpiece and by a hot cable to an electrode holder of some type which makes an electrical contact with the welding electrode. 2348036826053 abstract a two pole type of an a c variable current welding machine was designed and constructed. Some models have the same control driver floors only igbt transformer etc. In order to improve the quality of the welded products we must develop welding machines with on line sensing and control capability.
