As inverter of welding current with fast thyristors with microprocessor control UAFR-315M1.

Compact inverter rectifier of welding current provides:

• manual arc welding by consumable stick electrodes of all types with diameter 2-5 mm (MMA);
• argon-arc welding by nonconsumable electrodes (TIG);
• machine arc welding by steel solid wire with diameters 0,8-1,2 mm in carbon dioxide environment (MAG);
• easy ignition and steady arc burning
• safe reduced voltage of idle operation;
• stabilizing welding current or voltage;
• reduced power consumption while welding at idle running;
• welding in any attitude position;
• minimal metal spattering;
• regulating bending parameter from steeply-falling (TIG) to flatly-falling (MMA) and “rigidity” VAP (MAG);
• automatic selection of MAG mode at switching semi-automat;
• control of current and voltage with two pointer indicators;
• remote control;
• protection from thermal overloads;
• protection of welding circuit from short circuit;
• indication of operation mode, operating temperature sensors of quality control, main voltage and readiness for operation;
• protection from reduced and increased supply voltage, phase control.
