I'm not sure if it has anything to do with the problem, but you have your torch and work clamps reversed. You want the torch power lug on the positive lug and the work clamp on the negative lug.

If the machine was working properly and you had a foot pedal attached, with the switches set...

In theory you could probably bend delicate components or flatten cooling fins on the radiator, but you'd have to be pretty close and use really high pressure. I just avoid putting the air nozzle right on top of components and stay back a bit...never had a problem.

I find that using compressed...

I use a small paintbrush and my shop vac. You just lightly brush the dust and it gets sucked up by the vacuum. After that a couple of seconds with compressed air and you're set....

If a service tech gets caught sharing a service manual they'll get in quite a bit of trouble...probably get cut off by Miller entirely....

Have you worked on diesel engines before? If not, find someone who has.

Also, when asking for help on a forum it works a lot better if you put the real problem, or something close, rather than "help" as the title. Many people will intentionally ignore threads that don't have...

Nice! I almost hate to say it, but I brought home yet another 1987 Syncrowave 250 today ...

No worries. I suspect any decent electronics specialist can sort it out....there aren't too many components, and nothing particularly fancy from what I saw....

They're down to about $900 new, but it's an updated number....

I just changed my NAPA store to Los Angeles and the batteries still show up as East Penn. I did some reading and it sounds like that split may have gone away a couple of years ago....

There are manufacturers other than Johnson controls, but admittedly JC does make about 1/3 of the batteries in the industry. Even though they've moved the manufacture of the Optima line to Mexico they're still a good battery...maybe not as good as they used to be, but still good.

East...

With nice Thunderbolt AC/DC examples selling for $300 pretty regularly, why bother modifying an AC model? You can probably get $150 for the AC machine so it would only cost $150 or so...seems like a much easier path.

I've had a couple Thunderbolts with and without the handle/wheels. The handle is pretty weak and really only attaches to the sheet metal wrapper. One I bought had a small frame made out of angle iron with four small casters and that was better than the factory cart as you didn't have to tip it back...

The standard Dialarc 250 is 265A DC, but the Dialarc 250HF is higher at 310A....
