Direct Spot Welding Machine(DISM)
Direct Spot Welding Machine PAT.P
The DISM peels off magnetic wire coating and welds the wire in a single operation.
The DISM is an AC spot welding machine that has no need for pretreatment of the magnetic wire end.
The DISM is not in need of a separate process for peeling off coating, so increases work efficiency and contributes to improvement of the quality.
The DISM can also be built into an automatic wire-winding line as a welding unit.

Example of welding strength data (Unit:kg)
Terminal : Tin-plated phosphor bronze t=0.8
*Welding strength is depending on welding conditions,
wire diameter, and wire type; however, standard
horizontal tensile strength is 70% ~90% of strand strength.
|Wire type||Strand strength||Horizontal tensile strength||Ratio of welded
wire strength to strand strength

The KWA372A is a twin-electrode spot welder that has high welding pressure and current. It is particularly well-suited for welding work using large-diameter wires.
As an option, a sensor unit for maintaining a constant fusing thickness is available.
Examples of use electrical equipment for automobiles, motors, generators, transformers,household electrical appliances.
