Butt Welders

Micro Wire Butt Welder suitable for butt welding of ferrous and non ferrous wires from 0.3 mm to 2.5 mm. Easy to operate, the table top model can withstand subsequent drawing of the wires.

» Welding Process
Micro Wire Butt Welder automatic welding machine has a set value of 10 for welding current and the initial upset gap. The upsetting pressure can be set according to the size of the wire. Special quick acting clamps are used to hold wire for perfect alignment of the ends to be welded. Welding is simply initiated by a press of button and the complete cycle is automatically completed with built in controls.

Wire Butt Welders are used for butt joining of wires/rods of mild steel, carbon steel, steel alloy copper, aluminum and brass etc. The clamping of the machines bring the end of the rods or wires together under pressure for welding. The end parts are welded by applying short circuit current to the joints.

The jaws of the machines are arranged in such a way that it facilitates welding of wires over a wide range of diameters of specially shaped cross sections. The same Jaws can be used for annealing with extended jaws. The mechanical timer provided with the system is automatically tripped, after the job is done. Welded joint can withstand high tensile and can be easily drawn upto minimum size.

» Transformer
The transformer of the welding system conforms to national and international standard specifications. Primary and Secondary wounding of th e coil are of solid electrolytic copper of ample section, suitable for withstanding continuously temperature of 155°C. The transformer is fitted in a light welded framework.

» Regulator
A regulator is provided on the primary side with 8 different stages to control the current based on the demand of the application.

» Additional Facilities for annealing at extra cost

• Extended annealing jaws from 4" to 10".
• Separate heat regulator for annealing with foot switch.
• Annealing time will be control automatically by providing an electronic timer.
• Lighting lamp with flexible stan

Sterco Band Saw Butt Welder is the result of many years of experience, research and development. It is the most modern method of joining Band Saw Blades giving a joint strength 25% higher than that of the base metal strength. It eliminates the old process of overlapped brazing. Resistance welding is quick and automatic, thus eliminating human error and giving a perfect and strong joint. The mechanical timer provided with the system is automatically tripped, after the job is done. Welded joint can withstand high tensile and can be easily drawn upto minimum size.

» Welding Process
The Band Saw Blades are cut straight exactly at right angles and free of burrs. Welding current, upsetting pressure and upsetting way are set according to the blade width the blade ends being rigidly clamped by special quick acting jaws. By Depressing the welding lever the automatic welding cycle starts. The two ends are heated upto forging temperature in a few seconds, then automatically forged (upset) and current switches off.
