Ok, I'm running a Perkins 300d right now, mine runs 99ocv at 1800rpm I don't go up because it's already pretty watery at 99, I roll the rpm's back to 1700 at the least, that gives me around 92ocv and that's where I like it for 70plus rods down hill pipe. Am I hurting my machine? I don't think so because if I had the sense to get one with a kubota I would have custom arc and wouldn't have to break out the wrenches to roll the rpm's up or down. I feel like everybody jumps on the guys who tweek there own machines, while I know there are people reading these forums and then heading out to the truck tools in hand that don't have the mechanical sense god gave a cricket! There are some of us who take the time to learn, ask questions and figure the what Ifs and why's of what we are doing. The common answer being " if Lincoln had wanted it that way it would be that way" but I say horse pucky to that! Lincoln made it for ironworkers, pipeliners, mobile welding services, rental units, and about a million other reasons. If I can adjust my machine to better suit my techniques and processes then who can fault me? I don't advocate rolling the rack because I tried it and didn't like the outcome, I work with guys who bump theirs on a daily basis, I realize some things can be detremental to the life of the welder but don't jump on everyone who turns a wrench on their own machine! That said every reputable shop I have ever been into and asked the question said DO NOT BUMP THE RACK. For what it's worth I don't do that "anymore"
