Abstract
The paper describes the possibility of construction of systems of control and regulation, powered by the welding current source voltage. A simple and effective technical solution is proposed, which allows solving both the problem of protection from high-voltage surges during the welding process, and powering the semi-automatic machine systems during short-circuiting of the arc gap. The above technical solution was implemented in a range of semi-automatic machines of modular design of PSh 107V type and is now used in industry, being independent on welding current source applied in the arc welding process.
Keywords: mechanized welding, control system, electric drive, welding current source, welding voltage, power, protection, circuit
