Are these small oxy-acet tanks any good?

[TurboDSM]

My Grandpa had these, he got them from the local blacksmith when he closed his shop. Hoses are trash, regulators probably are too. I would need to transport them 400 miles to get them home, otherwise free tanks.

I can gas weld, but only have a single car garage to work in, so small...

Might be the Q1 component that caused simmilar problem on my mm135. here's the thread: http://www.millerwelds.com/resources...speed-too-fast

Q1 specs should be listed on the digikey link from my last post on that thread....

I had the same problem on my MM135. I finally found it on the back side of the front plastic cover, inside where you find the guts to the unit.

Got it done. The wire wheel did OK but I ended up using a flap disk on the heavy rust spots.

One coat of the Rust Reformer. Just a light coat of sandable primer (I like to do a light sanding before paint) and 3 coats of paint.

I don't know if the 130 is similar to the 135, BUT...have a look at my thread here, solution is at the end:

What you described sounds a a lot like my issue (no penetration, inconsistent arc, weld bead...

Good ol' Rust-Oleum...lol Reminds me of something I'd pickup at wally world when I was 12.

Seriously, is it worth using or am I going to be redoing it in a few years, even with a good solid topcoat?

Thanks again Heiti...

Making progress. Still a lot of work to do with a wire wheel.

So a self etching primer?

Now I can't decide what to do...lol

This thing doesn't need to be perfect. Etching primer sounds a bit more simple with less room for error than phosphoric acid/primer process. I suppose it might depend on how much rust I'm able to physically...

Thanks Mike, something to keep an eye out for as far as epoxy primer. Muriatic (Hydrochloric) acid...not sure I want to venture there. I would be better off grinding the rust out....

[TurboDSM]

Thanks Heiti. Heavy stuff, like heavy rust? Looks like I need something that can keep the cavities under control....

Any one ever use rust remover acid called "OSPHO"?

It doesn't require a water rinse like some of the other rust converting chemicals. Water is the last thing I want to put on bare metal before paint.

If I use an acid like this, I don't think it would be wise...

Thanks, the guy I bought it from pulled it from a Forester. It's going on an Impreza though. Already mocked it up and it should fit no problem (my 97 Impreza and his 2000 Forester have the same basic chassis). So I have a class III hitch going on an application that normally would only have a class...

Pics!

Thanks for the info myistar. I hadn't really thought about the type of primer, so that is really good to know.

I'll try to get a pic up in the next day or so. And I'll try to do an after shot when I'm done.
