Here is the info. I'm attempting to weld up an aluminum tank. Material is .080 (2mm) sheet stock. I have the 3035 spool gun with .030 and .035 aluminum wire. I have a pure argon tank and made sure I have no drafts where I'm welding.
I've tried the recommended #3@50-55 and get lots black burns, if I switch to #2@65 the black turns more to grey. If I up the # or down the wire feed, I loose control of the arc . NONE of these welds look good (globed, moutainous with pores, or not covering the cavity) Sometimes I'll start a weld and it will look good, shinny, coined, but then BAM burn a hole..... I've also tried starting and stopping, man that was the worst. Sooooo, I'm open for help PLS..
I want a TIG machine, is it going to be harder than this???
Sorry for the lengthy post, just wanted to include all the info. Thanks
