Unit welding AP-21 type
The unit welding the AP-21 type as the hinged equipment on the MTZ-80.1.26 tractor, the unit called further, is intended for food two-on point duty by direct welding current at manual arc welding, cutting and a naplavka of metals.
The unit is intended for work in the open air. Nominal parameters of the unit
are provided in tab. 1 treat its work at the height no more than 1000 m above sea level, air temperature from minus 40 to plus 40? With and relative humidity of air (average monthly value) to 80% at plus 20? Page.
The unit provides a possibility of performance of welding works in the absence of power supply networks. It is used for performance assembly and emergency repair work in construction, when making pipelines, repair of agricultural machinery in field conditions.
