And what is the operational difference between MIG and TIG?
TIG is like an electric ox-acetylene in that the filler is not part of the heat process. The electrode is not "consumed". MIG uses the filler as an electrode, so it is consumed. Technically both use shielding gas, but MIG and "wire-feed" seem to be almost synonymous, though they are NOT as there are wire-feed that are not MIG. I _think_ all MIG are wire-feed, though. Operational difference. TIG is two handed welding, one hand holding the heater, the other the filler. MIG is wire-fed, so is one-hand welding. _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
