Wire Butt Welding Machine

The welding operation of these machines is automatic and all settings are easily effected. The electrode spacing is adjusted on a lever set against a plate calibrated for wire diameter. The upsetting pressure is adjusted by means of a dial calibrated for wire diameter. and the welding current is selected by a rotary switch.

The wires to be joined should first be cut straight, exactly at right angles and free from burrs. The wire ends are then rigidly clamped by spring loaded clamping devices which can be opened singly or together by foot pedals. Both the hands of the operator are free for inserting the wires. Releasing the foot pedals leaves the wires clamped under adequate pressure.
