This is a discussion on another board. Is it correct?
:--weld----weld---\ torch in this direction is pushing , and like mentioned above it produces a LESSER penetrating weld compared to Pulling. Push is great for 16g 18G , and thinner. In this position you can see really well. Of course thickness limits are mainly type of project etc.
-------weld-------/ Pulling- this position does produce more penetration. It is slightly harder to see the puddle.
For clarification all info above is for welds NOT I repeat NOT in the vertical position.
For vertical only if you travel up , and you are pushing you will put more heat down & more penetration.
If you go vert down (MIG only) , and you pull then you get less heat & penetration.
It is a universal thing when talking about MIG only that push & pull are talked about in the flat or horizontal position so this is why once in awhile you'll get someone who does know what there talking about BUT will forget that we are usally talking about "things welded flat & horizontal" , and they say No No push is a more pen weld but they are really talking about Vertical only. Hope I explained myself clearly.
To others who replied:
HARD WIRE is NOT always push! If you have real facts lets see them otherwise you just gave ****ty advise.
Dont worry about torch maniplulation IE half moons it is not a good habit to do it just becuase you should have a real reason for doing this if you do.
I agree with what 66dean says. to cure it - dont exit you weld so quickly.
Others talked about the toes if you dont know its the outer edges of you weld , and YOU need to make sure that your torch is very close to 45 degrees to the joint to get your weld to have equal toes.
