High voltage capacitors for TIG arc starting and ignition
For TIG high frequency arc starting, plasma cutter pilot arcs and burner ignition.
TIG welders and plasma cutters start the arc with a high frequency, high voltage pulse that breaks down the gap; the high voltage capacitor works with a spark gap and step-up coil to produce it. Electronic igniters for gas and oil burners use a similar circuit. Consider B series parts rated 6–15 kV, E-8KV / E-10KV parts and the larger-diameter SL series.
Typical equipment
- TIG welders
- Plasma cutters
- Gas / oil burner igniters
