FAQ - Cobramatic Wire Feeder
MIG Welding Push-Pull Systems
Q. Which wire feeder best suits my needs?
The Cobramatic® Pro Series wire feeders are designed for the hands-on manual welder, And easily lends itself to automatic operation.
Q. Will any of my Cobramatic MIG welding guns fit any Cobramatic wire feeder?
Yes. All welding guns currently manufactured by MK Products, Inc. will work with any currently manufactured Cobramatic wire feeder.
To connect the Python or CobraMAX torches to the older model wire feeders P/N 150-003 and 150-005, an “UPGRADE KIT” (P/N 005-0713) must be installed into the Cobramatic wire feeder.
Q. What sort of adjustments does the wire feeder need??
There are no adjustments required in the wire feeder: only select Aluminum or Steel on the center spindle nut for spool drag and the same on the slave motor drive. Both of these settings can be found in the wire feeder owners manual or inside the lid of the wire feeder.
Q. Does the wire feeder require special drive and idler rolls for different sized wires?
No. The wire feeder comes ready to use with any size wire from 0.030" to 1/16". There are no special drive or idler rolls needed.
Q. How do I connect my wire feeder to my existing power supply?
There is an interface relationship between what the wire feeder requires from the power supply, and what the power supply requires from the wire feeder. Optional Power Supply Interface Cable Kits connect the Cobramatic Wire Feeder to most Lincoln Electric, Miller, ESAB, Thermal Arc and OTC welding power supplies.
Because of the many different power supplies that can have a wire feeder connected, the “Weld Control Selector Guide” available on our Owner's Manuals web page gives instructions on connecting not only the wire feeders, but MK spool guns, external contactors, and other weld control components. It is available at no cost from www.mkproducts.com. The Optional Power Supply Interface Cable Kits are listed below.
