The $64,000.00 question. With a flux wire welder on 16 or 18 guage metal do you push or pull the puddle.

only thing in oxy-ac they showed me in welding was to use for cutting, then on to stick/mig. i remember my dad brazing a cracked radiator neck back in the day. held
forever. thanks for the vintage manuals

I have the same question Hammond. Came to the conclusion after watching vid after vid on the net that I would just try both until I found which method worked best for me. Seems like so many folks use one or the other method that I could not find a definitive answer. More seem to push but is close.

Push & Pull Technique for Welding: Welding Basics: Techniques for Tig, Mig & Arc Welds | eHow.com

But I have maybe 5 hrs total welding time so dunno.

i have never flux wire welded before but since pushing a puddle has more penetration i'd say push. I push with my mig as well as the tig. when you pull it makes a thinner bead btw less penetration tho

The weld puddle always moves in front of the tungsten (TIG) or nozzle (MIG) regardless of the thickness of the metal...it is never "pulled"...the penetration of the weld is controlled by the angle and speed of the tig torch/mig gun , the heat setting and the amount of filler material (wire) added to the puddle..when welding Aluminum , the mixing of the shielded gases , Argon and Heliumn in the right proportions also affect the penetration of the weld...when looking for the best quality of steel welds it would be an Argon and Co2 mix..

Just remember "with slag you drag". Flux core would be pull and solid wire w/gas would be push. Dont forget to change the polarity of your machine when switching from one to the other.
