technical field

Background technique

Welding equipment is the equipment needed to realize the welding process. Welding equipment includes welding machines, welding process equipment and welding auxiliary appliances. Welding machines include welding energy equipment, welding heads and welding control systems. Welding energy equipment is used to provide the energy required for welding. Commonly used are various arc welding power sources, also known as electric welding machines. During manual arc welding, the arc length often changes, causing the welding voltage to change. In order to stabilize the welding current, the external characteristics of the arc welding power supply used should be steep, that is, with the change of the output voltage, the change of the output current should be small. Gas metal arc welding and submerged arc welding can use a flat characteristic power supply, and its output voltage changes little when the current changes. Arc welding power supplies generally include arc welding transformers, DC arc welding generators and arc welding rectifiers. Arc welding transformers provide alternating current and are widely used.
