Question on the new machine.

admin

I just got a new welder:It is a 1985 Lincoln Classic II with the Deutz Diesel. Went out tonight to test it out a little bit, this was the result.It is a crappy cell phone pic, but I am wondering if I'm way off base or right on the money. I ran the first pass DCEN with the big knob on 120-190 and the little knob about 55% using 1/8" E6010 + (158.5A)Then I ran 3 beads over the top of that DCEP with 3/32 E7018 H4 using a slight weave. I had the big knob on the 120-190 again, and the little knob about 45% (151.5A)Mind you I am cranked up on pain killers and muscle relaxers right now, but I thought that running 6010 was supposed to run a bit colder than 7018, yet I am running 10% higher in the same heat range. What do you all think?72 Chevy Cummins Project94 3500HD Welding Rig build Sold NOV 2011

Reply:I don't know about the DCEN since I almost never run that polarity.DCEP 151A sounds way hot for 3/32" 7018.  That's maybe even hot for 1/8" 7018.I'd also expect the 6010 to run lower amps than 7018 for the same sized rod.I wonder if the machine output is changing based on how you're running the rod.  You're probably running the 7018 with a real short arc, but holding the 6010 out to avoid digging a hole.  It could be that is effecting the machine.  Do you have any way to measure the current and see if you really are running what the dials say you are?Dynasty200DX w/coolmate1MM210MM VintageESAB miniarc161ltsLincoln AC225Victor O/A, Smith AW1ACutmaster 81IR 2475N7.5FPRage3Jancy USA1019" SBAEAD-200LE

Reply:Don't zap the multimeter!!!!!It would probably just blow the internal fuse and not damage anything, but I wouldn't risk it.You can make your own shunt if you have some source of low current (could be a battery and a power resistor), and a 4-wire ohmmeter (not likely), or two multimeters.Take a short piece of copper tubing and smash it flat.  Drill holes in the ends and put in bolts and nuts to make terminals.  Hook up your current source in line with one multimeter (set to measure current) and the copper tubing piece.  Hook the other multimeter (set to measure voltage) across the copper tubing piece.  The resistance of the copper piece will be really low and you may not measure much voltage.  Take a hacksaw and start cutting the copper piece in half. As you're cutting the resistance will be going up and you should start seeing some voltage.  The resistance of the copper will be R=V/I  where V is the voltage you read from one multimeter and 'I' is the current you read from the other multimeter.   Keep sawing until you get a nice round number for the resistance.  0.1 ohms would be nice for testing welders since that will give you 1 volt per 10 amps.After you've cut and tweaked the copper piece to 0.1 ohm resistance, install it inline with your welding lead.  Hook a multimeter across it and set it to read voltage.  Take the voltage number and multiply by 10 to get the current in the welding lead.  The number will probably be varying all over the place while you're welding.  An old analog meter might be easier to read, or use an average mode on the digital multimeter if it has it.Dynasty200DX w/coolmate1MM210MM VintageESAB miniarc161ltsLincoln AC225Victor O/A, Smith AW1ACutmaster 81IR 2475N7.5FPRage3Jancy USA1019" SBAEAD-200LE
Reply:Decided later in the week I am going to take it up the street to the welder repair shop and have em put it on a load bank, see how she runs then.72 Chevy Cummins Project94 3500HD Welding Rig build Sold NOV 2011

Reply:metal looks to be 3/8" ?if you could get any gap and bevel on the root id think 100-110 amps would be good, all dcep...either rod...but you gotta set it where you like it, not the other way round..Last edited by weldbead; 07-05-2011 at 04:06 PM.
Reply:Sorry to hear about your accident. I think you're running too hot, also. Different people/forums call things different ways. On the volt side the correct setting would be second gear/90-120. On the amps side it should be 55-60 for 1/8" 6010 and 65-70 for 3/32" 7018. On the amp side you can adjust the heat either way 5-7 amps to suit your personal preferences. All machines are somewhat different. Try starting here and work it out. Run them both DCEP and again DCEN. Lincoln says they should run DCEP but I have always had better beads DCEN. Since joining this forum I have found out the polarity can be reversed from factory settings by flashing the field wrong and probably other ways too. All I know is DCEN works best for me, maybe my polarity is backwards??Only when the last tree has died and the last river has been poisoned and the last fish has been caught will we realize we cannot eat money.                                         -Cree Indian ProverbSA 200 LincolnVictor Torches
Reply:First thing is to not think that setting those knobs is going to give you values you can calculate with a calculator -  like you did in your first post.     It don't (nor never did) work like that. the big knob on 120-190 and the little knob about 55% using 1/8" E6010 + (158.5A)
