  • Broke my psi gauge, anything to look for when buying new ?

    So I broke my welding regulator psi gauge. The one that sets the psi at the gun. Anyways do I need to look for anything inparticular when buying a new one ? Are the thread pitches pretty much all the same ?

    Is the inlet the size of the hole on the regulator ? Cause I measured the size on the gauge its self and its 3/8

    The 'Inlet' measurement is the size of the threads on the gauge/regulator. Most domestic regulators/gauges have standard pipe threads (NPT). On consumer machines the vast majority of regulators have 1/4" NPT gauge ports, some lower-end models are 1/8" NPT, and some very large industrial models are 3/8" NPT.

    Pipe sizes aren't measured by the O.D./I.D. of the threads, but rather by the ID of the actual pipe. If your gauge's threads measure 3/8" O.D., it is likely a standard 1/4" pipe thread.

    As for a replacemanet, any good quality gauge with the same range as your old one will be fine.

    When you install the new one, put 3-4 wraps of Teflon thread tape on the male threads, and be sure to tighten the gauge with a WRENCH - There should be a square shoulder just above the threaded portion of the gauge. DO NOT put too much torque on the case of the gauge (tightening it by hand), or you will destroy it.

        Of course nothing can be easy for me. Went to the welding store by my house and they said the lincoln gauge fittings are weird. They gave me a guage but of course it does not fit and they don't have anything else.

        So does anyone know of any sites that sells gauges for lincolns.

          Bob,

          Which gauge broke? The high presuure side is a "psi" gauge; the low pressure side is a flow (CFM/LPM) gauge.

          Try going here and click on "Quick Links", than "Servide and Warranty", then "Parts Navigator" and look up the part # that you need. Then, you can order it from Lincoln.

            Slash, not meaning to bump heads, but never use tape on gas joints, if a piece were to tear off it can prevent the regulator/solenoid/valve from seating, not much of a problem with argon or CO2, but O2 or acetylene, whole 'nother story.
            this applies to household gases as well.
            use teflon dope if you need teflon.

              Was that the right link Hank ? The psi, the one that you can control how much flow and what not is the one that broke.

              The guy at the place said he will order directly from lincoln and it will be here in a week, but for some reason I'm just having my doubts all together.

              Do you think it matters that I bought the mig welding kit seperate from the machine ? I mean it was ment to be used with lincoln and the guy at the welding place said, someone with another lincoln came in with the same problem.

                no, Ol' Hank gave you Lincoln Electric, you need Lincoln Weldershttp://content.lincolnelectric.com/p...rts/lemenu.pdf

                lookee up your numba from here.

                  There is no part number on the gauge

                    Bob,

                    Get the part number from the regulator. The rest of the goodies on it will be subassemblies.

                      use teflon dope if you need teflon.
                      That's why I was always told to not put the tape on the first two threads.

                        Same here.

                        I use teflon tape on nearly everything. Applied correctly, there isn't a problem. Remember, you only need a couple wraps. I've seen people apply a dozen or more wraps - That is excessive and can lead to problems.

                        I've seen a lot of equipment rendered useless by sloppy application of pipe dope. Most people apply WAY too much and it oozes/drips everywhere. Another potential issue is trying to disassemble fittings that are caked with petrified pipe dope.

                        All in all, I feel safer using teflon. To each his own.

                          Finally got the new gauge, but when I installed it, and when its finally tight the gauge is backwards. Anyway to fix it ?

                            You say "fianlly tight". The gauge has NPT threads (tapered). If you tightened it TOO much initially, you have probably ruined the threads! Tapered threads need to be pretty tight to seal. If you have it to where you think it's "tight", it may still have enough left to spin it one half turn more so it faces front. Also, you can try backing it off 1/2 turn, and then leak test it with soapy water. It should install and face the correct direction, as that's how it's made.

                              Well I messed around with it yesterday.

                              Basically I hand tightened it, then I put a wrench and was very careful not to over do it , and there is no way it will spin any more.

                              When its facing the right way its to loose, loose enough where if you bump it, its going to loosen some more.

                              So I guess I will just turn my bottle backwards.
