Press pin

admin

Digging around in boxes has me feeling like a "has been".Below pictures were taken around 1990-91. It's a con-rod pin for a 4000ton National forging press. The pin was machined to remove fatigued material and built up with Weld Mold 535 3/32" cored wire. About 300lbs applied.That fella filling the sub-arc hopper and a small group of employees bought the company a few years after I left them, and are doing well. "Gotta love that"!Matt Attached Images

Reply:I ran a sub arc welder not that size but the idea was the same. It had 2 welding heads on it. 5/32 wire was normal size....BobBob WrightSalem, Ohio  Birthplace of the Silver & Deming Drillhttp://groups.yahoo.com/group/southbend10k/http://groups.yahoo.com/group/sawking/1999 Miller MM185 w/ Miller 185 Spoolmate spoolgun
