Low sensitivity and current resistance, resistant to high welding current impact
LS low inductance structure is suitable for high-frequency inverter working conditions of welding machines, which can carry large ripple currents during welding, withstand instantaneous current surges during welding, ensure smooth output of welding current, effectively reduce arc breakage and splashing problems, and improve welding quality.
Low consumption voltage regulation, absorption peak protection core device
High quality polypropylene film medium, low electrical loss, can quickly absorb circuit ripple, suppress voltage spikes, protect IGBT/MOS tubes inside the welding machine, reduce core power device failures, and lower welding machine maintenance rates.
High temperature resistance and aging resistance, long service life under workshop conditions
The whole parts are made of industrial grade high-temperature resistant materials, which can withstand the internal high temperature of the welding machine during welding. They are resistant to aging and do not decay. There are no problems such as media falling off and potting glue softening. The workshop is free of maintenance for long-term continuous use, saving maintenance costs.
Explosion proof and flame retardant, safer for use in industrial workshops
Built in explosion-proof pressure relief structure, combined with UL94 V-0 flame retardant packaging, eliminates the risk of capacitor explosion and fire caused by overvoltage and overcurrent from the source, adapts to the electrical environment of industrial workshops, and provides more reliable use.
All solid structure, strong adaptability to complex workshop environments
No liquid filling, no leakage hazard, with moisture-proof, anti vibration, and anti workshop dust characteristics. The non-polar design perfectly adapts to the AC/DC circuit of the welding machine, and can work stably in various industrial workshop conditions.
Standardized design, ultra convenient installation and replacement
Multiple voltage/capacity specifications are compatible with different welding machines, supporting two methods of welding plate/bolt fixation. The standardized size fits the compact installation space inside the welding machine, making it worry free and efficient for both new machine assembly and old machine maintenance and replacement.
Suitable for various commonly used welding machines and welding supporting equipment in industrial workshops, typical applications:
Manual arc welding machine, argon arc welding machine, gas shielded welding machine, plasma cutting machine, high-frequency inverter welding machine, spot welding machine, collision welding machine
