I just got my 1982 Lincoln Idealarc TIG Stick 250 -250 ready to weld. I have a Bernard water cooler and there is a 120V socket on the face of the machine where the cooler could plug in. The problem is that the outlet on the machine is only hot when the foot pedal is depressed and the line contactor is energized. That means that after a weld pass, if you took your foot off of the pedal, the cooler would stop. This is not ideal. It would be OK when you start welding since the water would then start flowing and would remain on while the pedal is being used. When you have finished a pass, however, the torch is hot and the cooler would stop when you remove your foot from the pedal. I suppose that this could possibly heat up the torch unnecessarily. Obviously, some rewiring is in order. One look at the schematic tells me that the only 120 V power source is the auxiliary transformer and that is only energized when the pedal is down. I could use it as is by moving away from the work while keeping the pedal depressed for a few seconds after finishing a pass like a gas after flow, but I fear that I may forget. My Miller Syncrowave 200 is set up for constant cooler power already and the Lincoln manual says that some of the later machines were wired so that the power was on whenever the switch is on. Has anyone rewired a similar machine for constant cooler power? Is there an updated schematic out there somewhere?Miller Millermatic 252Miller Syncrowave 200Liincoln AC-DC 225Victor O-A Set

Reply:I have a 1985 version of that machine. That outlet should be live when the machine is on. I have no idea why your outlet is only working with the remote.My machine didn't come with the outlet but years ago I added it to run a water cooler because I didn't want to forget to plug the cooler in and melt a torch.From what I remember the machine had a small 2 amp transformer that only ran the pilot light. I put a larger transformer in (8-9 amp, don't remember exactly) and it was wired the same except with the outlet in the circuit. The outlet runs a Coolmate 4 and a small bench grinder with no problems. May have worked with a smaller transformer than I used but I didn't think the original 2 amp was enough. It wasn't that complicated going by the schematic pasted on the inside of one of the side covers.Ernie F.

Reply:I solved the problem this morning. When I finish connecting the wires I added today, the 120V outlet will be on with the fan when the machine is switched on. After removing the side panel, I noticed a large transformer at the lower left side (facing) of the unit. A look at the schematic and the wires showed me that this is the auxiliary transformer that drives the fan and, when connected properly, powers the 120V outlets on the face of the machine. All there is to do now is to wire the outlet so that both wires connect to it with one wire passing through the fuse block on the face of the welder. I'm guessing from the size of the transformer that it's probably at least 10 amps. It's a step down transformer from 240V to 120 and also 24V. It will have more than enough capacity to handle a Bernard Water Cooler. I wanted to document this operation in case anyone else has the same issue later. It's all downhill from now on. LOL.

Reply:Update: Wiring is all done and working now. The auxiliary receptacle is now powered when the on switch is on. Best of all none of the magic smoke was released. Thanks to those who responded. Miller Millermatic 252Miller Syncrowave 200Liincoln AC-DC 225Victor O-A Set
