ZD5 series (multi-characteristic) SCR rectifier arc welding machine produced by Changsha State-owned Dongfang Electric Works in Changsha, Hunan Province has two output characteristics of constant voltage and constant current and excellent dynamic characteristics. Stable arc, small splash, beautiful weld formations. Applicable to all grades of DC arc welding electrodes, especially for alkaline low hydrogen type electrode for all-position welding. Can replace the rotary DC welding machine, for manual arc welding, carbon dioxide gas shielded welding power welding and welding, submerged arc welding power supply. The welding machine adopts double anti-star thyristor rectifier circuit with balanced reactor, centralized control components, with remote control device, easy current regulation, output range; with voltage and current negative feedback, can automatically stabilize the welding voltage And current, to maintain the static and dynamic characteristics of welding stable, to ensure that when the grid voltage wave
