Sorry, Just had to crow..

select welder on software, press pedal..
25lbs air on a 1" cylinder, 2second delay, then 2500milleseconds (2.5sec) of current and then it releases when you lift pedal

First nuggets were at 4,000 ms.. too long

This is the 422/232 card that talks to the opto22 serial cards at 44,600k

Works fine,

THEN, Software Select Rousselle press on software, depress same pedal, roussele press strokes to/lift pedal or limit bottom..

OR, Software select 50ton press, depress pedal, strokes to either depth selected via box or bottom limit switch. Makes a clean repeatable break with the piranaha die in there.

OR, just turn off the computer, 50 ton press is manual.

COCK a doodle doo.. it is done.. onto something else.. (are ya happy fer me?)

CCW:
I put I think a 25amp SSR in. Yeah, I used your waa-waa pedal first too. (snicker)

I still owe you a beer on that.

I think I might have a extra SSR. I wired it into a receptacle, cut the tab on the Hot side. Wired the SSR on the top, wired the line on the bottom, took a 2 conductor to the lil cube relay.

Yeah, weld time needs to be up to 5 seconds, as the tip degrades, Air pressure has as much to do with it as current time. over Pressure deforms the tips too fast. You can't see it, but I tack welded a nut onto a piece of 1/2" square stock, drilled a 1/4 hole, bent a horseshoe shaped loop and drilled the ends of it for a tie wire. This goes around the handle and retracts the welder handle back up as the cylinder retracts.

If I was you.. instead of a microsecond computer.. all you need is a relay and some timers.. pedal, time out (clamp_time 2 sec) then current_time 1sec to 4 then current off then when lift pedal clamp off. SO two timers. If you unclamp while current is on you spark your tips *not good. 25lbs half way up welder handle is plenty.

Flatline's Up!

I didn't understand half of what you said, but I'm dang sure happy for you http://bbs.homeshopmachinist.net//smile.gif

I realize it's a spot welder (or panel welder)... can you describe what did you do to it for us "slower folks"?

Thanks,
Britt
