I am working with a Small 110v flux core welder. It came set up as an AC machine. Flux core wants dc current. The secondary output is around 26 volts with, I think, 125 amps max. So far I have taken the secondary into a bridge rectifier rated at 1600v and 200a, from there it goes to a 89000mfd cap, and finally out to the ground and lead. With this set up there is still a charge left in the cap after weld is complete. I was thinking of adding a resistor across the cap to discharge it after each weld. Will this work, or would it cause a failure somewhere? If it would work, any idea what size resistor would be best?
