Blaster!
Your specific comments on the dreaded NR 232 are very good! Very few welders I work with, excepting those in Los Angeles, really like to use it due to it's particular characteristics. Unfortunately the Lincoln application guides do not put forth this specific information regrding wire speed and voltage at the arc. It would be fun to compare some additional notes regarding wire speed, voltage, torch angle, methods of progression, deposition rate and such to compile a practical users guide for success with this wire. Let me know if this interests you.
Now to take off the inspector hat and put on my welding hood for a moment. Have you had occassion to run the new terchnology NR-233 wire touted in these parts as the replacement for the NR-232? I am on roll number twenty seven and rather like the stuff. It is very forgiving on wire speed, voltage, position, etc and is very smooth. It does however appear to have a very generous slag coating beyond that of NR-232 and as such does not seem to have as high a filler metal deposition rate. Our local supplier can only get 1/16" diameter on 12.5lb sppols so I have tried direct comparason on a structural retrofit project with two LN-25 feeders one with NR 233 and one with NR-232 at .068" diameter. My conclusions forementioned are based on this testing. Your comments woulkd be appreicated as I am the only one according to local supply sources running this wire in my area. And as such have limited opportunities for varied use.
Regards!
