This past weekend I made a stupid move. I was pushing some downed tree branches with my loader when one of them fell against the vertical exhaust pipe. The torque transferred into the exhaust manifold which broke it. My experience with welding cast iron is limited to handrail work.
I would like advice on welding this manifold. I have TIG and Stick machine. A Miller Dynasty 300 inverter.With a water cooled TIG torch. 100% Argon shielding.
I would like to know, should I preheat the manifold? What filler rod should I use?
The biggest job may be removing the manifold without breaking the bolts.
