I have only been welding for about a month. I have been reading up on welding Modes. Sort of after the fact cause I got pretty good at welding 1/8 Aluminum through trial and error. But, I figure as soon as I go to a different metal (change alloy and/or thickness) I will be right back at the drawing board. So, I want to better understand what needs to be in place before I start. I'm pretty sure I have the basics from reading articles and from an earlier thread on this forum (which was extremely helpful).
Anyway, my question is; Do I always need to be in Spray Mode to weld Aluminum? And if my tip is not recessed into my nozzle, does that mean that I'm not in spray mode? Or can i still get there just by turning up the voltage?
Also, since I use 100% CO2 to weld steel and 75%/25% for Alum., does that mean I always use short circuit mode for steel and Spray mode for Alum. (by default)?
