Cut the Nozzle to Match the Tip?

admin

Today I got out my Millermatic 130 xp with co2/argon and tried my new gun nozzle that is flush with the end of the tip.  The diameter of the hole in the new nozzle is smaller than the diameter of the hole in my old nozzle.  I am experiencing depostion of unwanted material on the inside of the nozzle that is decreasing the space between the inside of the nozzle and the outside of the tip.  I am considering grinding off the end of my old nozzle so that it is flush with the end of the tip.Is my new nozzle has an inside diameter of 3/8"Is it described as (1) 3/8", self-insulated, (2) 3/8', self-insulated, flush(3) 3/8. self-insulated, tapered?Is grinding off the end of my old nozzle a good idea?  I am considering doing this because the Miller video I watched said that the end of the tip should be flush with the end of nozzle.  I am using a Profax.mig gun.    Any suggestions are appreciated.
Reply:I run one that I shortened up all the time on lighter gauge and low amp material. As a side note they make tapered tips just for use with the 3/8ths nozzles.
Reply:I like the smaller nozzles, they get into corners better.  Just get yourself a pair of Welpers and clean the nozzle often.  Only takes a few seconds to keep the nozzle nice and clean.  If you like the bigger nozzle then make sure to ask for it next time and/or take your old one with you as an example.
Reply:Nozzle dip will hep keep it clean as well. The deposits are just part of using a wire feed
Reply:Yeah it's ok to cut down the nozzle. I do it all the time. tapered tips are an option too.
