Sounds like you need to read the owner's manual.

How can anyone else give you "ideal settings" without knowing the thickness/material you plan to weld???

Straight argon? For aluminum. What else would you use? Magic dust?

The MM350P is an awesome machine but it's going to take some effort on "your part" to learn to maximize it's capabilities.

Quite frankly, these comments/questions sound more like they come from a guy who just bought a HH 140 (first welder), than from someone who just bought a high end professional machine.

WelderBC,

Exactly what in my post was "semi-ignorant"?

Is it because you think you have a high IQ (???) that you don't need to read the owner's manual?

Is it because you think other posters are mindreaders and should know what thickness material you plan to weld?

What other "gas mix", since you've done so much reading, do you think you may want to use to pulse weld aluminum?


If you don't wish to be treated like you're ignorant, don't post like you are.

WelderBC,

The whole point behind my previous posts is the fact that the MM350P is a very sophisticated machine. Not a basic squirt gun welder you just turn on, set the voltage/WFS and start welding.

This is definitely a case where the Owner's Manual can be your best friend.

I would highly recommend you go to millerwelds.com and click on the Resources tab. There you will find an offer for Miller's "Student Pack". It's $25 including shipping. Includes an excellent Tig Handbook, a GMAW Handbook, a GMAW-P Handbook, and a bunch of other useful goodies.

The GMAW-P handbook will explain the pulse welding process about as well as anything I've seen.



PS. If you've got it "frying bacon" then you've got your setup wrong. Spray and Pulsed Spray sounds more like "bees buzzing" than "bacon frying".

As has been mentioned, the gas mix selected is critical to satisfactory results when using the GMAW-P process.

ironman,

You are aware that aluminum GMAW is a SPRAY ARC process.

Not going to get his "stack of dimes" with straight spray, so he must have had the pulse turned on.

To the best of my knowledge, none of the pulse programs that come with the MM350P or Miller's Optima Pulser call for an Argon/Helium mix. I know they don't for the Optima.
