I have heard that the whole peice would need to be pre-heated and stick welded. Anyone know anything about this? Can I use my wirefeed on it?
I know normally you dont want to weld on cast iron becasue it weakens it but im just looking to seal the crack and illiminate the noise.
If you TIG weld it then it doesnt need to be pre-heated.
