The guy who built it claimed it was a 30 ton, not honestly sure.Bummer - glad you weren't hurt. The welds look like they didn't penetrate very deep. Is there any support below? OR, just that butt weld?
What tonnage are you using? size of cylinder and PSI?
I just picked up on the very first sentence in the OP, setting the weld shouldn't have had all that much pressure on the press.Setting the weld on a 256 layer damascus billet and press went POP!
No pressure gauge, it's a converted log splitter. I purchased it along with a bunch of other tools from a smith who closed his shop. I'll snap some pics shortly.Again, be sure to get a welder who is familiar with welding heavy material for the repair. There is no way to pull that all back together with metal cold. You'll need to strip everything from the frame and start over. Not a big deal, just time consuming - and time is money.
Would you mind stepping back to give a couple of photos of the full press frame? Those closeups of the welds show the crappy welds, but not really how the frame is designed and put together. Looks like it's a "C" type frame? That design surely does put LOTS of stress on the single column.
Is there a pressure gauge on the system? If so, any idea of max pressure the system is set at?
