Answers and Hot Tips
TIP #1: If you are planning on welding aluminum most or all of the time, upgrade your Cobra® MX with the insulated groove drive roll kit. Part numbers for wire size specific kits are listed in your owners manual, or call MK for details. Keep the standard knurled drive roll for spare part or switching back to steel or flux cored welding.
TIP #2: When ordering a new Cobra® MX be sure to order the model that uses the same consumables as any existing guns in your shop. You may already have many cups and tips that will work on the Cobra® MX Gun!
TIP #3: Unlike the Python or CobraMAX, the Cobra MX guns all have the original MK valve body and stem installed. To make better use of the Pre and Post Purge function of the Cobramatic® cabinet, replace the standard valve stem with a Modified Valve Stem, P/N 431-1080.
