1.Trim the interface of the band saw blade, clean both ends of the band saw blade.
2.manually fix and clamp the band saw blade to the welding electrode head, adjust the welding current, turn on the welding switch for welding, re clamp the band saw blade after welding, select the tempering current, turn on the tempering switch for tempering.
3.After you complete bandsaw tempering, polish the welding slag to finish the band saw blade repair process.

UNBAS50 Band saw butt welding machines with automatic annealing infra-red spectral pyrometer for bandsaws steel strips of 14 to 50 mm
- It uses a manual clamping handle and a motor-driven cam mechanism, so there’s no need for an air supply or air compressor, making it very easy to use.
- Our motor-driven cam disc creates the butt flash.
- A precisely adjustable spring mechanism generates the machine upsetting force.
- We can freely adjust the annealing temperature control voltage, and set the annealing time anywhere from 0 to 10 minutes.
- It automatically releases pressure during the annealing process.
- Depending on production needs, we can also install a water cooling system on the main and critical welding electrodes.
