Anyone with a Tig 300/300 know what the microfarad and voltage ratings are for the power factor capacitors?
Reply:Can't even begin to answer with out the code number of your welder. there are about 4 different versions made over 20 years that are quite different.Those caps will help your power use when welding but up your standby power use.So if this is a home unit. Turn it off when not using it.
