Improved MIG Nozzles From ATTC

American Torch Tip has just released two new versions of the Bernard 4491 nozzle. The 4491-HD and the 4491-XHD.

The 4491-HD is based on the standard Bernard® 4491 nozzle but includes a new brass insert designed to protect the insulation, extending the life of the nozzle.
The HD stands for Heavy Duty and is the result of changing the material to copper and making it thicker which will hold up better to heat.

The 4491-XHD is an Extra Heavy Duty version of the standard Bernard® 4491 nozzle. The new version offers the maximum wall thickness incorporates a brass insert to protect the insulation from wear and is manufactured in copper in order to hold up better to heat.
