Arc OK intermitent issues on torch fire

So this appears to be the 5V relay docs

It appears to be 1 amp at 30 volt DC so the 90 Ohm resistor ( 2 x 270 Ohm) will give 267 mA @ 24 Volt so its still within spec.

So 2 of these would do the job?
I checked for traces and connectivity but neither connect them together.

If that is the transfer relay then you shouldn't need any contact wetting. The minimum switching current for it is 10uA at 10mV.

My mistake, you need three!

Would using one cause an issue? or just not be enough for the desired effect?

only following through with this as i had swapped my one 1k 1watt resistor for one of the 270ohm 5 watt. because the manufacturer was vague so i didn't want to overload the relay with all 3 at once. But on that note was cutting great with the new 1 resistor until this afternoon when i can only assume something has let the magic smoke go as when the torch tries to fire now there is no pilot arc or ArkOK signal coming back to the GUI. so maybe i have blown the transfer relay i am thinking.
