I did a search and found a few things but have more specific questions...
Is my 75/25 argon/co2 mix not enough argon?
All I am getting is some black soot and not penetration...
do I need to clean the Al better?
Also what are some basic heat and wire settings to start with...
Welder is a Lincoln wire-matic 255 with a spool gun filled with .035 Al wire on 1/16 to 1/8 thick scraps
Thanks
