Error #3 on the Promotech Rail Bull machine indicates that power is not supplied to the main motor. If the PCB shows no voltage supply to the drive motor, the recommended solution is to contact the service center for inspection and repair.

    1. GENERAL INFORMATION 1.1. Application The Rail Bull welding and cutting carriage is a track carriage designed to produce butt and fillet welds by using MIG/MAG torches with the handle diameter of 16–22 mm (0.63–0.87’’), and can cut steel by using oxy-fuel or plasma torches. The carriage can work in the following welding positions: PA/1F/1G, PB/2F, PC/2G, PD/4F, PE/4G, and PG/3F/3G.
