New Welder

[miangus]

Well, new to me. A few weeks back I bought a welder on a local online consignment auction. I was not able to go look at it, so I bought it sight on seen, not a good plan. It was part of an estate and I got it for under $200.00 so I took a chance. It's a Miller AEAD LE-200. A friend and I went and picked it out, it was on a nice cart, so it loaded easily. Upon getting it home I started it up with a jump pack. It ran and welded but the carb was messed up. I rebuilt the carb and it started and ran ok but the carb idle circuit had an issue I could not fix. So, a new carb was ordered and installed. It started and ran perfect. I have done a few test welds, 7014 horizontal to look at the welds you would swear I knew what I was doing. It has a add on High Frequency box with cables to connect the AC outlets to the box and a TIG torch in addition to the DC leads. I know nothing about how that would work, but the TIG torch looks well used although it appears that was a few years ago. Not the SA 200 I always wanted but it will do.

You got it for a good price. I need one. I know a guy who bought one maybe a little newer with the Onan engine. I offered him $1500 not running but he won't take it.

The carb on my generator is different.
What we think of an idle circuit is different.
Idle on a generator is full speed.
You try to slow it down the engine run right and you think you have a bad carb and a bad idle circuit.
Increase the speed when it is not under load and see what happens.

You done good. Very good.

I believe that type of welder generator has 2 speed settings, 3600 for welding and 1800 for the generator, so the carburetor has to work properly at both settings. I used a welder like that on construction 51 years ago, it was a good machine, if I lived off the grid I would have one now!

I have one of those with a Kohler engine on it.It has a rod through the block,but the machine has thousands of hours on it.I'll probably never fix it,as I'll probably never do any more outside welding again.Was a very smooth machine doing horizontal welds on well casings when drilling welds.

I'll have to measure the RPM on my generator.
My point is the carb on my generator doesn't have an idle speed.
The carb has is a power jet for heavy loads and a jet for low power. RPM's are the same.
I have to adjust the idle stop on the carb butterfly to keep the rpms up to normal. May that be 1800 or 3600.

If I don't have the idle stop set right, it sounds like a normal carb with a bad idle circuit.

Those welders have different circuitry than your generator. It has been a while since I was around those welders, however if I remember correctly, they have a toggle switch that is either set to weld or power to bring the engine to the right rpm, depending on if it is being used to weld or as a generator. Then another toggle switch for auto idle can be set ON or OFF. It controls a circuit that drops the engine to an idle speed when not welding. It picks rpms back up when an arc is struck and drops back down shortly after welding stops. Or the switch can be set to off for welding processes that need the welding generator at full output and cannot use the idle auto speed pick up function.

I had one of those for over 40 years.
Put a new short block in it once.
I put a Lot of hours on it and I made a lot of $ with it.
The older ones have a big knife switch under the panel opposite side from the battery that you have to switch to go from weld to 110/220 AC power. The throttle has 3 settings - idle, 1800 rpm for power and 3600 rpm to weld.
I just sold mine this spring. Still worked good but I don't need it any more.
