Separate division ISKRA of VPT-Neftemash LCC- Russian manufacturer of welding equipment, more than 75 years, produces a wide range of products: welding units, welding generators, contact welding machines (spot welding machines, butt welding machines, seam welding machines), transformers welding, automatic welding machines, inverter power supply sources, construction metal structures, block-modular buildings, mobile housing units
Designed to supply a welding position manual arc welding, used to work in the field, because design includes independent power source in the form of an internal combustion engine.
The unit allows the welding electrodes with any type of cover, since power is supplied from the constant current source, which serves as an inductor- type generator with a current rectification, efficiency of 70%.
Welding trailer unit ADD-4004.9 can be operated at temperatures between +40°C to -45°C. It has a high performance and reliable protection against external influences, so it is often used for work in the field. Iskra welding equipment factory offers this model at an affordable cost .
Ratings refer to the unit 's work at an altitude of more than 1000m above sea level, the ambient temperature between +40°C to -45°C and a relative humidity (monthly average) to 80% at +15°C.
