The key differences between the two cables are u003cstrongu003ematerial u003c/strongu003e(either a Hytrel tube or steel monocoil is used at the center of the cable to allow passage of the gun liner, the wire and the shielding gas flow) and u003cstrongu003eprice u003c/strongu003e(the steel monocoil cable is more expensive due to the use of steel monocoil at the center of the cable).u003cbr/u003eu003cbr/u003eThe steel monocoil provides extra structural integrity to the cable giving it superior pinch resistance which helps to ensure good gas flow and wire feedability. Users in certain industries or welding applications that require longer gun cables that may frequently be looped or stretched around corners to the point of pinching are the ones who should consider upgrading their welding guns to our specialty steel monocoil cable. The majority of our welding gun users never experience these issues and enjoy long, dependable product performance with our heavy-duty industrial grade cable.
