Welding positions

[welder_guy]

I know there is positions like 5G and F2 ect. That tells you the position and parent metal configurations. But my question is can it be welded with any kind of process?

The position designations you mention tell nothing about the parent metal.
The position designations tell you,well, postions.

G = groove joint
F = fillet joint
R = with restricter plate (for pipe)

1 = plate flat, or pipe laying down and rolling
2 = plate horizontal, or pipe standing up
3 = plate vertical
4 = plate overhead
5 = pipe, but i forget the position, i think laying down not rolling?
6 = pipe at an angle, no rolling

You can use just about any process in any position, except spray transfer mig, which is only useful in the flat and horizontal positions due to excessive puddle fluidity. Pulsed spray transfer mig can be used in all positions though, with the right settings.

Not all stick electrodes are suitable for all positions. E7024 is for flat/horizontal only. The 3rd digit designates the position. 1 = all position, 2 = limited position.

5G is a horizontal pipe, vertical weld, no roll.
6G the angle is 45 degrees

Welding positions, on your back, sitting down, underneath, up on ladder.

This is a little off topic. I have a mm 350p but I have never used pulse mode. How would you compare out of position welding in pulse vs short circuit? Much of the welding I do is repair so it can be in any position and on any condition iron 16ga up through 1/2 inch or heavier. I am using straight co2 and .035 or .045 70s-6 wire. Guess what I am really trying to decide is should I go to the trouble of getting some 85/15 or 90/10 gas for pulse. Straight co2 or 75/25 are easily available but that's about it unless I special order it and drive quite a ways to get it.

you forgot in a mud and water filled trench

So your sales people managed to sell you the best machine they could but managed to drop the ball when it came to being able to even use it??
Please don't take this as if I am being mean spirited but why did you buy the 350P in the first place ?? Pulse is what it is all about. Otherwise you should have got the plain jane MM350.
To put it in real world terms....sure you can do just fine with just straight mig and turn out great work. We have done that forever. GMAW-P is just something that seems to me to be a bit easier to get better results with as far as clean spatter free work goes. I am thinking I find filling gaps easier as well.
It is sorta like having a Dynasty instead of a Syncrowave. More buzzers and bells but in the end it is really how good of a machine operator you are. But that said a good operator can get better results from a better machine.

I bought it on the internet. My son needed a welder so I gave him my mm250 and got a 350p because I wanted one. From what I've read it's supposed to be quit a welder. I've got an aluminum trailer so I'll probably get a push-pull gun and learn aluminum some day. I've read that spray transfer won't work out of position but I haven't found out much about pulse.
