- The entire system is controlled by Electronic Panel based on Thyristor and D. C. Drive Control Panels

Manufacturing Process:- Set the desired welding points (depending on the mesh size required) and start the machine- The line wires from the Pay Off stands are fed to the machine from the rear side through wire guides. - Cross wires duly pre-straightened and cut to length (equal to the required width of the mesh) on Wire Straightening and Cutting Machines (optional equipment) are dropped from the rack on to the welding station. - The line and cross wires are rhythmically welded. - The speed of welding is controlled through the control panel.

application: - suitable for upset but welding of all profiles of wires and flats of iron, steel, alloy and carbon steel, copper, aluminium, brass and other light metals and their alloys

features: - upset travel - movable platen travel on two parallel guides- upset pressure - provided by a precision spring action on the movable platen- clamps - lever operated adjustable 'floating' steel clamps of precision quick acting design ensure firm preset clamping pressure. Release quick and easy.- electrodes - special wear resistant copper alloy electrodes provided with precision 'v' grooves, permit rapid and accurate alignment of wires- adjustment of welding current by means of a 8 step rotary switch from 50% to 100%- electrode spacing - obtained with ease by a lever set against an indexing plate, adjusting in 10 steps- annealing facility - separate annealing electrodes with screw type clamps provided for ease and quick annealing of the welded job

Welding Process: - The Saw Blades or Wire Ends to be joined should be cut straight, exactly at right angles and free from burrs on special shearing attachment (optional equipment)- Welding Current, Upsetting Pressure and Upsetting Way are set according to the blade width- The blade ends are rigidly clamped in special quick acting clamps provided on the machine- By depressing the welding lever, the welding process begins- The two ends are heated to forging temperatures in a few seconds and are then automatically forged (upset). The welding current switches off automatically- The job is de-clamped and the weld completed

Process for Annealing: The upsetting way switch lever is now turned to annealing and the job is clamped again with the extended jaw distance which comes in automatically on flipping the lever to annealing position.- By pressing the annealing switch on which two heat positions are provided, the job is annealed in order to normalize the brittleness of the welded area.- Depending on the type of material, the annealing process should be repeated several times if need be.

Set the desired welding points (depending on the mesh size required) and start the machine, The line wires from the Pay Off stands are fed to the machine from the rear side through wire guides. Cross wires duly pre-straightened and cut to length (equal to the required width of the mesh) on Wire Straightening and Cutting Machines (optional equipment) are dropped from the rack on to the welding station. The line and cross wires are rhythmically welded. The speed of welding is controlled through the control panel.
