ur so smart
Mission Accomplished!
I gave in and picked up a microswitch from radio shack. I figured this was the safest way to wire this welder and not burn it up. So I reversed the electrode and the work, then installed the microswitch in the stinger on its own circuit.
This was the problem. The single wire coming from the trigger got its power from the weld current and switched on the feed. Reversing the current put this switch on the high voltage side of the weld.
Here's the new switch installed. I wrapped some tape around the conductor to make sure the switch wires wouldn't short to it.
Here's some practice welds. On the far right is the practice weld I did the other day when the polarity was wrong. Welds: (left to right) 1. grooved w/ two passes 2. flat surface pulling 3. grooved w/ one pass 4. flat surface pushing.
It looks to me like it's got good penetration, and they are pretty good looking welds (clean) for flux core.
BDR
welds look good I like to clean them up with a wire wheel on the grinder and skip the chipping hammer
