Hey guys this mite be a stupid question. But you normally push the gun mig welding . But is it true you get more penetration if you pull
I’m a amateur I push and pull, probably 90% of the time I push though.
tons of opinion and content on the web some of it is this opinion some of it has physics behind it. I’m sure for professional applications there are key considerations but if your new I would just get stuck in. Push is easier to see, control and looks better so try and lean towards that but don't get hung up on it if your starting out.
No matter whether pulse or standard spray Mig on Aluminium you should always push unless there is absolutely no physical way that you can.We tried a pulse mig on aluminium at the welding suppliers and when you pulled the torch there were black spots in the weld, pushing was perfect indicating that gas cover was lacking in the pull weld. Increasing the gas flow didn't make any difference. On steel I tend to use whatever direction is convenient.
