I'm quite the novice when it comes to metal work. I think ignorance has caused some trepadation or fear over time to working with metal. I happen to like wood. Well, that not being the point here... I recently bought a Hobart MIG, 110 v, and torch set up. I'm learning as I go here, so thanks for being patient with someone who knows nothing. Perhaps enough to know that I shouldn't do any welding at this point of consequence. I bent a pallet fork for my Dingo a while back and I"d like to straighten it. I bought a head for my torch to heat the fork so I can bend it back in shape. Before i fire up the torch, what should i know? I do not want to ruin the fork by heating/cooling incorrectly. The dealer who sold me the torch head told me to be careful about my gas mix, as it might be easy for the flame to be sucked back into the torch. Does this make sense? The tip I bought I heard someone refer to it as a "rose bud". I hope I'm making sense.
