The filter capacitor for welding machine is a non-inductive industrial capacitor having plastic case and enveloped with flame-resistant epoxy resin. Our filter capacitor boasts strong over-current, low temperature rise, easy installation and resistance to high voltage. This metallized film capacitor is widely used as filter capacitor in welding machines.
