The Cobramatic®push-pull wire feeding system is a great example of Lincoln’s
MIG welding expertise. The Cobramatic incorporates a push-pull drive system
that virtually eliminates the problems associated with wire feeding. This unique
master-slave drive system prevents tangling and damage to the wire, resulting in
increased weld quality and productivity. Combine that with some great new fea-
tures that make set-up easier and adjustments virtually unnecessary, and the
Cobramatic is a great MIG welding choice for all wire types.
