I checked and eveything is working but it is not putting power to the wire. it feeds the wire and the fan is going... any ideas on what and how to check it? it is a century250.

Thanks

See the last post. thanks guys.

Check your connections where the cables come into a main block. There should be some sort of metal block with two studs and two cables bolted there, I'd check that first.
 
At the transformer? I checked conections to most everything and it all looks tight!
 
find the century factory service manual.. hopefully online..
without it youre flying blind

begin diagnostics

1) Discharge the capacitors so it is safe to be inside the machine... if you dont you can receive a hi voltage shock that WILL kill you... do not skip this step... DO NOT SKIP THIS STEP.. if you dont know how to do it you shouldnt be in there
2)Methodically begin checking all connections, obviously there is power to the machine... but there may not be power to the transformer or capacitors
3) Next it will be the silcon controlled rectifier and the diodes
4) Transformer test

thats pretty much a simplistic diagnostic... the service manual will have the trouble shooting section and wiring diagram which are both invaluable

Lastly.. welder repair station.. century is an off brand and parts are harder to get... but they are still around...
IIRC that has a tweeko gun on it ..right? make sure the gun connections are also good.. I suspect they are because you are getting 110v to it...
it was my first welder...then I went red for life

btw Lincoln aquired Century in 2003 and now they are begining to look like lincolns... but they have cheaper components inside.. I looked around lincolns site to see if I could find any shop manauls or anything pertinent about them,,,, I couldnt.. google didnt help much either... but give it a shot

sorry I couldnt be more help

Thanks. I know how to discharge Capacitors from a points system. you just toss them to a friend right?:D I looked too for a shop manual and also ran out of luck. maybe I can call Lincoln and see if they have one. It is a Red unit and looks like a Lincoln.
 
Check make make sure its full of jet fuel ... regular wont work and that your flaps are down and ready for take off....If all else fails trade it in for a nice F16 of maybe a Apache helicopter.............
 
my money is on the relay might be dead, mine doesent always work because the relay is bad, and the contacts are worn.
 
Fixed it!

I contacted lincoln tech support and they knew exactly what to look at. The guy who owned it previously Mickey moused where the hose mounts and gets its power feed right after the rollers. Dumass didnt know what he was doing. The guy on the phone from lincoln was like(there should not be any allen screws there!) Ah ha. I refitted the hose properly and she works great again.:D I am a happy camper again, even though I suck at welding:haha:
 
I know the difference and am even a certified welder but that was 20 years ago. I just need a bit O practice. I was out yesterday and was able to make some sweet beautiful welds and got it dialed in. today though, is another story. They SUCKED ARSE today.
 
you might need to adjust it every day.

At the shop I used to work at the power was ALWAYS low in the mornings, you had to crank it up to get it to run right, then later had to drop it back down because it was way to hot :dunno:

that a little bit in the country so maybe the power lines sucked
 
I am allways working with different metal too so I am alwasy trying to get it right.
