If there is no arc either check the relay is working (clicking) when you pull the trigger if it is test it is switching if it isn't test for voltage to relay coil.
Just read it's clicking check voltage across the contacts they often burn out
You need a multi meter to read the voltage when the trigger is pulledYes the relay is clicking .
How would I test it
Do you also have a contactor (bigger relay) inside the machine
Relays can be had easily I've ordered relays same as those from ebayOk Iv got a multy meter I'll have q go at it .
But getting parts for it might be a hassle .
