***honduhhh_head's fab thread***
Question about welding aluminum:
I've been practicing some and ran into an issue today (has happened before) where when I go to dab the filler rod, it starts to melt and ***** up the rod. It doesn't flow into the puddle. Also, when this is going on, it almost seems like the filler doesn't wanna flow at all, if the ball comes off the filler, no matter how much peddle I put to it, it doesn't seem to flow then boom it goes flat. Also in this situation I seem to be getting a ton of contamination that seems to come from the filler. What gives?

I'm using a #9 torch, so the lens isn't all that big, however the cup expands to the size of a #12 cup on a jumbo lens.
try pre-heating the area with the arc, without actually trying to penetrate. do this for a few seconds, then create a puddle that can be manipulated with torch angle, and now add your filler. this should help clean up the filler, because the a/c inverter is cleaning the material before you're trying to add contaminated filler. make sure your filler hand/glove is free of dirt (i have separate welding gloves and fab gloves, some guys use rubber doctor gloves on the filler side when welding aluminum). if this doesnt help, i have a couple other things to try too, but do that first.

I'll give that a try and post some pics for ya. Thanks for the tips.
Hey thanks for the tip about using the torch with a little pedal to clean the base before welding. I haven't run a bead yet, but I did tack some stuff up tonight and it did make my tacks look better and the filler flowed in no problem.
It definitely works better than throttle down and jamming filler in to start.
