EMEPI15 pneumatic welding gun, “S” version.
Pneumatic welding gun with 15KVA power at 50%, “S” version.
EMEPI pneumatic water-cooled welding gun with 15KVA power at 50%. Equipped with only one cooling circuit for the transformer, arms and electrodes and adjustable working stroke. A rotating group allows orientation of the welding gun in any position. The operation can be spot by spot or in continuous sequence. Pneumatic wide opening of the lower arm. All models are equipped with MICROBOX FACILE, a separate weld control board containing the control power and the differential magnetothermal switch. The MICROBOX FACILE weld synchronous control board with a diode microprocessor controlled in 5 steps is equipped with the double programme and pulses. All welding guns are provided without arms. A large range of standard arms are available on request. Bespoke solutions can be provided upon a customer design. The “S” version offers a higher distance between the centres of the arms.
