Transformer, Secondary Cable, Performance Output
Bulkiness transformer with clumsy secondary cable cause current loss and reduce 40% of the working rating. Fully concealed one-structure in compact size and no secondary cable need. No current loss and achieve 90% of working efficiency rating. 48KVA of WPI Guns efficiency current output equivalent to 165KVA Cable Gun.
Energy Efficiency
High KVA requires high power supply. Larger power is needed to compensate the loss of the seconday cable. Electrical energy costs will increase. Small KVA in high output and no current loss. High efficiency and energy saving choice.
The bulkiness of the secondary cable limits the meneuverability and causes poor operability. Small, nimble and 360° rotational use. Great maneuverability.
