Box transarc 140

[Leighton92]

Just got my hands on a box transarc 140 it sparks but won’t run it’s as if it’s got very low amps even on the highest setting

Any ideas ?
Thanks

A spark but low power implies that there is a high resistance somewhere in the output circuit, i.e. a bad connection. Not a lot to go wrong on these, so I would suggest opening it up and looking for loose, corroded or burnt connections.
