Ya that would be the obvious answer but i mean is there a way of doing this with out removing the bushing only becuase sometimes bushing dont alwasy like to come out if it's a soild rubber and it just pushes out fine but if it's the type with a metal sleeve wraped around rubber than it's a bitch...

Just mig it and cross your fingers depends on how much length you have to weld. If it's small you'd probably be okay.

take a wet rag and wrap it tightly around parts you want to keep cool when welding.

thats what we do when brazing temperature sensitive parts in refrigeration. I don't see why it wont work when using a welder.

good luck

eastwood sells an anti-heat compound

No idea how or even if it works, I've just seen it in their catalog.


otherwise it's wet rag FTW

you could tig it.. And just run it for a few seconds (with the wet rag trick) then walk away for 10 minutes.. repeat , repeat, but by this time you could have pressed out the bushing...

htpweld.com makes some really bad *** heat stuff and its reusable. Never used it but everyone raves about it. It's called the heat sponge (although its not actually a sponge)

I was gonna say the same thing, being in the HVAC industry we do this all the time to protect certain "at risk" parts such as valves using rubber o-rings. Just be sure to keep it wet enough.
