Transformer

Regulator type
250 / 600Amps

Mini Arc Welding - 200 Amps

Stud Type 150Amp / 250 Amps

JK Air Cooled & Oil Cooled Welding Transformers are manufactured in different capacities to suit requirements of all industries - both Repairs and production in small scale and big scale.

The looser in these transformers are kept to minimum by selecting and using best quality silicon stampings, copper wire and conductors.

The Arc stability is excellent on account of sufficient high open circuit voltage. This will also enable the use of stainless steel and type of electrodes.

All models are manufactured in stepless regulator current system to obtain optimum welding efficiency at minimum loss of current.

POWER FACTORS CAPACITORS:
Often the electric supply authority is particular about power factor of equipments installed in their area. As transformer type welding machines have inherently low power factor, the use of power capacitor is recommended. Suggested size is mentioned with specification and will be supplied at extra cost if desired.
