INVERTER RECTIFIER OF WELDING CURRENT


Purpose of the development: Designed for high-quality manual arc welding of pipelines and other steel structures for various types of electrodes with a diameter of 2-5 mm in the installation conditions.

Recommended application field: In various sectors of the economy

Technical characteristic: Power supply - 380 V; Rated welding current - 200-315 A; Open circuit voltage - no more than 80 V; Low voltage no-load - no more than 12; Range of welding current - 40-315 A; Current consumption on each phase - up to 12 A; Power consumption - no more than 13 kW; Efficiency - at least 80%; Dimensions - 600x410x546 mm; Weight - not more than 55 kg.

Advantages over analogues: The built-in voltage reduction of idling of 6-8 B gives the possibility of welding in high-risk conditions, such as boilers.

The development stage readiness: Introduced in production

Description of the development:
()
Setting the welding current is continuously control on the front panel of the scale in absolute values ??and the current can be increased gradually to 30% by using the remote control from a distance of up to 25m. To check the actual value of the welding current of +/- 5% voltage drop in the welding cables to 8 V at currents of 40-200 A and 4 V at currents of over 200 amps for the whole temperature range. To check the actual value of the welding current rectifier is equipped with a vibration resistance ammeter of class 2.5. Protective frame made of metal tube protects the rectifier against mechanical damage during transport and provides easy portability within the work area. It has a security cut-out: -No one phase; -Increase the supply voltage by more than 15%; -short-circuit of welding wire for more than 2 seconds; -peregreve in violation of operating conditions. Ability to work outdoors under a canopy in the operating temperature range of -25C to + 40C.
