Overview

Bernard Style MIG Nozzle (5-Pack) 4391, 4392 – 200/300A

The Bernard Style 4300-series MIG nozzle is a heavy-duty brass slip-on nozzle for 200/300A Bernard-style MIG guns. It slips onto the 4335 gas diffuser, where O-rings hold it securely while allowing infinite adjustment of the tip recess. Choose the 4391 with a 5/8 inch bore for general-purpose welding, or the 4392 with a 1/2 inch tapered bore for better access to tight joints. Built to OEM specifications and sold in packs of 5. For 400A guns with the 4435 diffuser, use the 4491 and 4492 nozzles.
