Not trying to start a flame war here, but this machine is driving me nuts.I used to run a big Miller Syncrowave 350 with a foot control, and I could weld damn near anything perfectly first try. Long travel on the pedal, very fine control. My personal machine is a Dynasty 200DX with a thumb control and it does ok. A bit awkward at times, and I do plan on getting a foot control to smooth it out, but I can do pretty decently on steel, stainless and aluminum.Latest one I have available is a Lincoln Invertec V205, and I hate this machine. The control seems to go from barely on to full power with no transition, and I have such a hard time getting a stable repeatable arc that it's not even funny. I'm toying with just bringing my own setup in to work so I can show them I really do know how to weld, but I'd rather tame the Lincoln than put the hours on mine.Am I missing something on the Lincoln, or is there a trick to setting it to actually work the way I want? As it is, I only set the peak amps for about what I think I need, and the start amps just a little below that, but it just varies so fast it's a royal pain to make it work right.
Reply:Nope, in my experience lincoln TIG welders are junk. The controls are poorly designed and seem prone to failure, the arcs never seem to be as stable or smooth and over all dont seem to be as user friendly.Ive used miller 250's and dynasty 200's extensively and couldnt be happier.Have we all gone mad?
Reply:I have used (Older)Syncrowave 250's and New Dynasty 350's... About 5 years ago, I was using a New Lincoln PrecisionTig and it worked just fine.I would like to help, but I have no experience on the Invertec V205's.I have things that I prefer about each manufacturer, but I wouldn't describe either as "Junk"Later,Jason
Reply:You really need to use another Lincoln Invertec V205 to see if it is that particular machine or just the way the Lincoln's work.Ed Conleyhttp://www.screamingbroccoli.com/MM252MM211 (Sold)Passport Plus & Spool gunLincoln SP135 Plus- (Gone to a good home)Klutch 120v Plasma cutterSO 2020 benderBeer in the fridge
Reply:I had one of them lincoln and I found the power settings brilliant, I even prefered it to the miller DynastyTiglerArgon In The Lungs, Helium in the Head
Reply:I have used a miller syncrowave 350 and a lincoln percision tig 275. They both worked great for me on steel. The arcs seemed about the same. I think the miller syncrowave was better when welding aluminium though.Ya gotta spend money to make money!
Reply:4x4_Welder, is there anyway to put a multi-meter on the control pot's legs? It sounds like you have a non-linear pot.If the resistance doesn't increase evenly around the pot's turn or the slider's movement??? Then the power supply could be doing "just what its told" by a bad control.A bad control circuit potentiometer would do exactly what you're describing. I have had that happen before, the amperage would go from too low instantly up to too high with almost no in between.That was on a torch handle mounted roller type pot and the torch had been laid down/dropped/banged hard enough to jamb the shaft of the pot into the control's body and it was toast. A multi-meter on the three legs of the pot when its rolled will tell if the control is the problem?Cheers,Kevin Morin
Reply:I prefer Miller over lincoln for tig big time.Here's what I like about the millers:If I set my amps to 100 & crack my pedal just enough to strike an arc I'm at about 25 amps or so, (not sure of the actual #'s) full pedal gives me 100 amps.On a lincoln, @ 100 amps, cracking the pedal gives me about 60 amps-100 amps @ full.& they don't have the little heel flange on the pedal, like a Miller to help against pedal wandering.It's a totall pain when using one on .030" or thinner alum..Don't get me wrong, my Migs & Engine machines are all lincolns, but My TIGs are Millers.Buy American, or don't whine when you end up on the bread line. |
