Welding unit AP-21 on the basis of tractor MTZ-80.1

Welding unit AP-21 on the basis of tractor MTZ-80.1 intended for use as a source power of two posts for manual arc welding, cutting and surfacing of metals DC.

The unit the basis of a wheeled tractor is a self-contained power supply of the welding arc. Welding generator driven by a diesel engine basic the tractor.

From the shaft the power take-off (PTO) of the tractor through a drive shaft and a specially designed matching reducer, torque is transmitted to the welding generator. The inclusion of drive generator is made from the tractor cab by the lever for engaging the rear The PTO. The speed control of the generator is carried out by showing the instrument tachometer installed on the dashboard in the cab.

In the shelter the unit is installed dvukhportovaya generator representing dvuhaktnoy induction machine high frequency, with each package independently from each other are working winding of the welding posts, which are almost eliminate the mutual influence of the posts welding to each other, providing sustainable long-term operation of welding rectifiers in nominal mode.

To protect parts mounted equipment from weather and mechanical damage, the unit is equipped with a canopy of welded construction, with doors access panels generator control (welding dvuhmetrovym).

The shelter at only protects welding equipment from atmospheric influences, but also allows you to store and transport various accessories: welding cable, remote control panels for remote control of welding current, welding electrodes, etc.. Except also, easier access for maintenance and repair.

Fabrication welding unit as separate attachments allows you to install it on other types of machinery such as crawler tractors of the type DT-75, vehicles with terrain and other special. technique with the PTO.
