I WAS TOLD BY A WELDER NOT TO RUN ON THE "SPECIAL APPLICATION" RANGE ON THE FINE TUNING, SOME ONE WHO REPAIRED HIS CLASIC 300 TOLD HIM THAT??? ANY BODY KNOW ANYTHIN ABOUT THAT THANKS

I consistantly run a 1/8 5p root in third at 40 or there about depending on pipe size and fit.Never miss a beat. Any time I need to push thru a tight fit I catch a gear in the same basic range. Its good down there. What is the reasoning? Honestly curious, not being an ass.

hey whats up rick, i was looking for an answer myself, the guy said his machine was giving him problems, and the guy who fixed it told him to stay out the range, i myself dont know the reason. i thought some one else knew somthing about it!!!!!!

I have a classic 300d-I was told to stay out of that range,dont know why.Sometimes on 5p I run on 45 anyway

Man, Im always in that range for 1/8 5p. My machine may blow up tomorrow because of it, I dont know. I can say 3rd and 40 -45 is perfect for a normal gap. The bead falls in without effort.
Maybe Presidential hopeful Kaye Sellon can clue us in to any chance of the alledged problem.

talk to tom fowler he'll know!

I just dont see how it can harm the machine. The engine is working to pull that the same as it would at a lower gear with a higher setting. As said, if its a problem, I aint hit it yet. Tell us Kaye!!

Howdy! Dang it! Thats twice Ive tried to respond directly to Mr. Jacobss, first time I just rambled some more. Anyway, Hi ! Hope we can resolve this issue, cause Im curious and want to hear some solid reasoning.

Hello JE Jacobs, I am not an expert on the specifics of Lincoln welding machines, however, I can tell you that the ranges and such that you folks are discussing are relative to bead performance and I don't believe have a major bearing on machine longevity. The only other anology that I would introduce into this thread might go like this: when vehicles with automatic transmissions and over-drives were first introduced onto the automotive scene way too many people didn't consider the limitations of running in the over-drive modes under certain highway conditions, this lack of education caused many transmission failures. In the case of your machines and the suggestions that were made to you, I too would be interested to know the reasoning for these suggestions. As I mentioned in my opening statement, the reasons for these adjustment choices are generally based on how the weld metal reacts when subjected to specific electrical conditions, ie, volt/amp relationships, volt/current curves, and other electrical specific characteristics. So, if there is some specific mechanical/electrical issue that this could cause I would definitely like to know what it is and why it is supposed to cause a problem. Best regards, Allan

    Allan, I must agree with You. If for some reason it is harmful to the machine to use a particular range at about 1/3 of the machines rated capacity, someone at Lincoln didn't do their homework, and I doubt that.

i agree with u all!!!!!!!

Still gotta wonder exactly what the reasoning is. Call him up!
