Hello eh,picked up a lincoln idealarc 250 AC today for 75 deneros ,got it home and wired a plug to she and tried it out.Well its very lethargic ,hard starting and very little penetration at 250 amps so i would assume its ill.any ideas where i should start looking?Any help will be appreciatedFelon Attached ImagesCaution lurker lives here" hmmm That is serious,pass the ganja and pick up a 24 of MGD"

Reply:Can't pull up the manuals on-line for the Canadian units.Can't make it out in the photo - is it a dual voltage unit? If so what voltages are listed, what is it hooked up for and what do you have it hooked up to?MM200 w/Spoolmatic 1Syncrowave 180SDBobcat 225G Plus - LP/NGMUTT Suitcase WirefeederWC-1S/Spoolmatic 1HF-251D-1PakMaster 100XL '68 Red Face Code #6633 projectStar Jet 21-110Save Second Base!

Reply:A wiring diagram would be a big help. That cap looks to be an AC high voltage, oil filled. It does something depending how its wired, looks like it has seen better days.
Reply:fred and duane You were in fact both right.the 220 was 120.but now i have another issue.The welder blows out one side of the double fuse as soon as its plugged in leaving 120 in its wakewhat now my wise sagelike friendsFelonCaution lurker lives here" hmmm That is serious,pass the ganja and pick up a 24 of MGD"
Reply:If you are reading 220v on the 2 lower wires on the switch (black and white ones that look new) are you reading 220v on the 2 wires directly above? If 1/2 the switch is dead you might be only getting 110v even though you have 220v going in..No government ever voluntarily reduces itself in size.

Reply:As transit indicated, the "beer can" is an output voltage stabilizing capacitor. Leads just connect to the welding outputs (as you can see in the photos). Could be the problem but . . .??If the switch dropped a hot leg there wouldn't be any output at all.Oops.

Reply:So duane Could the beer can be the culprit blowing the fuses or is it more likely a dead short lurking somewhere waiting to bite me on the ***???FelonCaution lurker lives here" hmmm That is serious,pass the ganja and pick up a 24 of MGD"

Reply:double check the wiring on the plug you installed on welder??? if the frame was grouded other than the plug, and the plug wired incorrectly trying to put voltage on the frame that would do it-- fredLincoln 180C MIG
Reply:Houston we have a problem their is continuity on the side with the white wire in picture.there appears to be no straps or wires touching the housing and the fan runs even after the fuse blows one side.Alas is there no hopefelonCaution lurker lives here" hmmm That is serious,pass the ganja and pick up a 24 of MGD"

Reply:fm how about unplugging and removing white wire from switch, check continuity (resistance from the switch term to ground (with the switch on) if none, check the white wire to groundyou COULD have an accidental ground say case pushed against table that has grounded tool on it, tho would expect to see a wire smoking in that caseHumor me and take your plug apart, that bare ground wire is against the white pin if your romex has a red, use black and red for hots and the white for ground -- less likely to have a short circuitLast edited by fredf; 11-06-2009 at 11:16 PM.-- fredLincoln 180C MIG
Reply:Fred said "Humor me and take your plug apart, that bare ground wire is against the white pin"You da man fred,the bare wire was touching the white pin.did another check and no continuity.Ill have to wait till tomorrow to check it out again as im out of fuses.So to all a goodnight and thanksFelonCaution lurker lives here" hmmm That is serious,pass the ganja and pick up a 24 of MGD"Originally Posted by fredfDuaneb problem on input if no ground on input would get no output with 1 blown fuse
Reply:And now you know. . . the rest of the story.felon, I just assumed you would have wired up your plug correctly so I focused in on the machine end. Missed the part where you said it blows the fuse as soon as it's plugged in. Appears to be another example of how one of those old bear of a welders just go for ever.Keep us posted.Last edited by duaneb55; 11-07-2009 at 12:01 AM.MM200 w/Spoolmatic 1Syncrowave 180SDBobcat 225G Plus - LP/NGMUTT Suitcase WirefeederWC-1S/Spoolmatic 1HF-251D-1PakMaster 100XL '68 Red Face Code #6633 projectStar Jet 21-110Save Second Base!
Reply:Duane said"I just assumed you would have wired up your plug correctly"(remember im electrically challenged)When i bought the welder the lad said he couldnt use it because it was blowing the fuses on his 30 amp dryer circuit.So when i got it rigged up , plugged in then finding the blown fuse i 'assumed' well maybe it wasnt his wimpy circuit that was causing the fuse to blow instead of checking my own workfelonps ill update after a trip out to buy a fusePss after i said ill pick up a meter in the am i found one like this on sale at the local Canadian tire and went out and snagged the last one for 20 bills,hence the testing last eve Attached ImagesLast edited by Felonyass Monk; 11-07-2009 at 07:24 AM.Caution lurker lives here" hmmm That is serious,pass the ganja and pick up a 24 of MGD"
Reply:I re-read all the posts again and looked at the photos very closely. Get the welder running again. I dont know all the Canadian electrical codes, however I see some not too safe conditions that need to be addressed, but before pouring more money into the welder lets first get it working and then bring it up to 2009 standards. Now that you have a volt meter, well need to know what the input volts and amps are from the tag on the unit and what the voltage is that you are supplying at the dryer outlet.
Reply:transit said"what the voltage is that you are supplying at the dryer outlet. "It was the previous owner using dryer outlet, i have a 60 amp dedicated line.However the problem was with my shoddy plug workthanks to fredf for that find,the ground wire was shorting on one of the hot leads in the plug.The machine is now up and running.After a good cleaning and paint job i will post some pics but it may be awhile i have been shirking the to do list for a while now.Thanks to everyone for your help.Felonps transit what are the unsafe conditions?Caution lurker lives here" hmmm That is serious,pass the ganja and pick up a 24 of MGD"
Reply:Ok, you have answered some of my questions. Is the welder 110 or 220 volts? What is the current draw listed on the machine tag, 30 amps? The 60 amp rating for the branch circuit you are using may be ok,
.. may. Once I have more info Ill be able to assist you bring the unit forward to 2009 safety standards.
Reply:Start simple and clean all the conections inside and out. Sand paper does the trick.safety last
Reply:The cable from the plug to the on-off switch looks to be Romex house wire and is not suitable for a line cord, too stiff. The wire gauge MUST be able to carry the full load rated current, for a line cord at, 30 amps you would want to be using# 10-3, flexible 3 conductor cable. The plug and outlet MUST be rated for the full load current although the bare copper is a ground conductor, if it were insulated there would be no concern of it shorting to any other conductors. The color for a ground conductor insulation MUST be Green, Green with a Yellow Stripe. The wires to the cap should be replaced, its time. If at all possible, look closely at the cap, there should be a part number, value in micro farads and working voltage, if the cap should ever need replacing now is the time to have the while the information is still readable.

Reply:Originally Posted by duaneb55fredf, The object was to check for a short on the secondary side that would cause a primary side fuse to blow due to excessive current draw.Unless I'm not reading your statement correctly.edit: I missed the part where felon said it blows the fuse as soon as it's plugged in.
Reply:Originally Posted by fredfDwaneb55if it was on secondary, fuse would blow, yes, but the primary circuit would no longer be complete and the fan would not run and Wouldn't get ANY outputbecause of the ground on the hot pin, he had 110v across the welder so it sorta worked no ground. no power. period.fred

Reply:Sweeeeeet.
Reply:sweet indeed
Reply:Not trying to be a smartass in hindsight, but that plug would have been the first thing that I checked. The ONLY reason I say that is because it is a mistake that I have made many times in the past. That kind of short is very easy to make, especially on plugs with small or tightly spaced terminals. I always look at anything that I may have done wrong first. Very glad that the problem was found and it sure is good to see so many helpful people here. Many would have given in but I think duane and fredf just thrive on a good challenge. Good on you both. Lookin' good!!! Quite a contrast from what you posted in the first pics. Like the flames!

Reply:If you try to change the wires to the cap. one of them may be resistance wire.Some of these welders had a coil inside a tube That looks like a fat wire until you look real close.Out side looks good. Just make sure your line cord is a cord and not romex.cable.We use soow cord on welders. |
