          they can't dictate the parameters with out also specing the thickness, joint type, and position. it's like setting a speed limit without telling you what road you're on.

              What size wire is this with? If it is with .035, you couldn't even lay a bead, all you would get is popping.

                Just cause thats what they say they want doesn't necessarily produce the desired results they want. Engineers spend lots of sleepless nights thinking up this stuff and are clueless of the process. Then again some are VERY good.

                      Just on the outside lookin in they probally set that procedure useing a suitcase welder that has a low and high side.18 volts sounds close for the positions and if they were reading off the low side amperage.This could be what they used. .02cents worth

                        I would almost bite on that if I could believe a welding specter knew what a suitcase welder was.

                          The so called "welding engineer"where I work is a complete retard. He has us welding 3" thick steel with 0.45 flux core and 1/8" stick rods. Not to mention he's got us setting the machines WAY to friggen low! Guy's are constantly getting incomplete fusion showing up on the X-Rays and ultra sounds. On most of the jobs proving to be a problem it's because the customer mandates that we follow all precedures exactly. Yet any time somebody finds the oppurtunity to deveate from the proccedures when no ones looking they suddenly start passing inspections (go figgure). Fittings on pressure vessels shouldn't fail inspection 23 times in a row! The guy's I work with are amazing welders and have always passed X-Rays with out breaking a sweat then suddenly this new engineer comes along and all he ll breaks loose. I was able to get a pretty good laugh watching our #1 guy trying to give him lessons on solid wire about a week ago. Needles to say he didn't seem to be to pleased too be playing teacher for the day.
