To Weld or Not To Weld(clamping?)
Troy, in returning your Cat to service, the time on the bench has no effect on the function of it. In welding the Austenetic S.S.(300 series, non-magnetic) sellect the proper welding wire, typically 308ELC. The welding process will probabley be Gas Tunsten Arc using Argon shielding gas. If it was me I would try clamping the cat back in place. Happy Trails Beep Beep from Houston.
