It is specially designed for Butt welding of ferrous and non ferrous wires from 0.3 mm to 2.5 mm to withstand subsequent drawing. This machine is a table model and easy in operation.

WeldIng Process:
This Micro Butt Welder is automatic upset Butt Welding machine. The welding current and the initial upset gap are 10 set according to the size of wire, the upsetting pressure being preset. The ends of wires to be clamped by special quick acting clamps to correct alignment of the wire ends. By pressing a push button, the welding cycle is initiated and completed automatically by built in controls. The job is now de·clamped and annealed if necessary, in the provided annealing device.

It is specially designed for Butt welding of ferrous and non ferrous wires from 1.2 mm to 8 mm to withstand subsequent drawing. This machine is a table model and easy in operation.

Sterco Butt Welding machines are designed and developed with outstanding dependability, exceptional accuracy for butt joining of wires/rods of mild steel, carbon steel, steel alloy copper, aluminium and brass etc. bringing together under pressure the ends of the parts to be welded and by applying short circuit current to the joints. The jaws of the machines are arranged in such a way so as to make possible the welding of wires over a considerably wide range of diameters of specially shaped cross section. Mechanical timer is provided in which it is automatically tripped, after the job is done. The welded joint can withstand high tensile, and can be drawn upto minimum size.

Transformer
The transformer of the machines is of special type, conforming to international standard specifications primary and secondary are of solid electrolytic copper of ample section, suitable for withstanding continuously temperature of 155°C. This 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 according to the requirement.

Annealing
The same Jaws can be used for annealing with extended jaws.

Additional Facilities for annealing can be provided 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 stand.

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.

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.

Annealing Attachment
The Upsetting pressure is now turned to annealing and job again clamped properly with extended jaws distance which comes in automatically flipping the the lever to annealing position. By turning the annealing switch on which the heat position are provided the jo is annealed in order to normalize the brittleness in the welded zone. Depending on the type of material, the annealing process must be repeated several times if needed.

Shearing Attachment
Special shearing attachment is provided on the machine itself for cutting the piece at right angles, except for model MB-3 + 4.

Grinding Attachment
The attachment is provided for removing the burrs from the welded zone. This unit is mounted on the machine.
