Blow your welders out..

[Sberry]

Body shops are the worst but I would never need to blow mine out. They sit in a relatively clean shop and I try not to blow grinding dust everywhere.

You know, Old Jupiter. Blowing out your welder every year or so probably takes less time than going through this, as well as trying to outsmart Millers engineering crew. Unless you really just want a filter, in that case, never mind.

Thank you again. I already see what I regard as a problem, but I'm going to have to make a couple of drawings and then have a pal show me how to scan and post them here.

Thank you very much for responding. Would you tell me some of the models that had filters? I would like to find photos and look at the installation. Without discounting your efforts, and being reluctantly willing to accept that you may be right about this, I still find it hard to believe that a simple, effective, long-working filter arrangement can't be devised.

You're very welcome, old jupiter. The following machines had filters: the Deltaweld 302, 452 and 652; the Goldstar 302, 452 and 652; and lastly the Dimension 302, 452 and 652.

We've also included the field instructions to our discontinued filter kit (part # 042939). Let us know if you'd like us to message them to you as well.



We hope this helps. Let us know if you have any further questions. Thanks!

Just did this to my Dynasty 200 when i was putting new feet on the bottom and removed the cover, almost choked on the dust.

Just have to ask-was that because of the filter or because of "inattentive" (I know you can't say just dumb when representing Miller) users who never changed them ?

Hi, Aeronca41. We found that filters weren't a very efficient way to keep the machines clean in the long run, which is why our wind tunnel technology was developed. We wanted to create an easier way for machines to be filtered and also eliminate the worry of having to change out a filter time after time. The wind tunnel technology doesn't completely eliminate the need to blow out the machine, but it does make it easier because you do not need to remove the case or cover.

Let us know if you have any further questions. Thanks!

Hi, old jupiter. We did have filters on certain machines years ago, but we found that the filters run a high risk of overheating the machines. Most of our current machines are built with the parts that need cooling in the path of the cooling fan, and the electronic parts out of that path so they stay clear of dust and other elements that might cause them to fail prematurely.

We hope this helps. Let us know if you have any further questions!

Thank you and weld on...

Okay, looks like I offered bum info, and that the mothballs may be a bad idea. In searching about whether the fumes are corrosive, I so far have found out that mothballs used to mostly be naphthalene (quite flammable) and are now more commonly 1,4-dichlorobenzene, and that the fumes of either variety are pretty hard on your bod. Also, the info is that mothballs are not very effective against rodents and snakes. Still trying to find out about corrosiveness. Maybe the peppermint oil is the way to go.

I still would like to know why we don't see welders with air filters and shutters, but any time I have ever asked this question it has disappeared without a trace, with nary a word from the company reps who sometimes have comments on other matters (who is the Miller man here?). In the meantime, I think I can find a square or rectangular automotive filter and airbox (for a 2bbl Weber) that I can put on the back of my MM-175, which is long-since out of warranty.

Come on, Miller, wouldn't you like your marketing guys to be able to brag about this innovation? Wouldn't you like your dealers to sell air filter elements?

If I was in a plane and a stinkin snake fell out onto my lap, it's quite likely that it would've been me bailing out that door when Frank opened it. I don't do snakes. At all. Well I take that back, there's only two kinds of snakes I don't like, dead ones and live ones, the rest are fine.

Recently sold my 304 XMT/22A to my old employer where I had left it just to return and find it still running but much abused. I’m looking for something not so industrial but still has the kick when I need it as well as light projects away from 220. What is the opinion of the Millermatic 211 with Running Gear?

I didn't buy the running gear but bought the old transformer MM211just before the inverter version came out. Love it. I have not heard any complaints about the new one -people seem to like it.

At the risk of hijacking this thread, the bugs in the pitot reminded me of another airplane critter issue. Frank had a Monocoupe and worked the airshow circuit in PA/OH way back when. He had a friend who had never flown and Frank kept pressing him to go for a ride. Promised no aerobatics. Finally decided to do it. They took off; all was well, and the guy was enjoying it until a rather large and unhappy blacksnake fell out of the overhead into the guy's lap. Frank opened the side window, grabbed the snake, and tossed it out. I don't think the guy ever went for another airplane ride, and I always wondered if someone on the ground was hit or nearly missed by a flying blacksnake.

Does anyone know if the fumes from mothballs are at all corrosive? Good idea to use them, but I'd want to know that answer before putting them in a welder. The old car guys use peppermint oil to keep mice out- they hate it.

Mud daubers and airspeed indicators are an age old problem. Some have the little flapper over the end of the pitot that lifts by pressure from the slipstream. When we didn't have one of those we always just put tape over it with a reminder taped to the instrument panel to prevent self-induced problems.
