Joey Collier hey man Merry Christmas to you and your family. I couple of weeks ago when I joined up there was some talk of WS stickers. I am trying to load my helmet lol. Any chance the are still available? Thank you. $?

This is my first attempt at 1/4" aluminum outside corner joints. Running 200amps, 100 hz, 40% balance and 1/8" tungsten.  After successfully welding out most of these mirrored 3 sided pyramids, I all of a sudden on the last half of the last weld had issues with blowing a hole in the outside corner joint. I let it cool, ground and cleaned the damaged area and tried again. Because of the increased width of the weld joint I decided to weave, but as I got close to meeting up with the previous weld things went sideways on me. Erratic arc, very hard time forming a weld pool and lots of porosity. Pictures are attached. Any advice would be greatly appreciated. 

This question is for JODY COLLIER since I joined this forum after watching YouTube videos hoping to learn from you. I have a body shop and I make rust repair panels and weld with my millermatic 135 all the time. I have never been taught a single thing about welding and never really got better. I mean I can get away with mig welding but I want to Tig and grow my skills. So I have been practicing like you said running beads and I can't seem to do anything decent on steel but am able to find myself creating better and better welds on aluminum. I need to understand why even when I'm following your parameters for 1/8 steel my welds are grey and my heat affected area is huge having no thin edge I guess the cleaning action like on aluminum. I am a very beginner to Tig with that being said where can I get the information I need to weld steel better?  Can you help me. Thank you for your time. A couple of pics one because if you can weld the blades that's cool and the other to show you my struggles in hopes for your point of view

My miller 135 mig machine has started acting up and I'm not sure what this is all about. Sometimes the weld is full of holes and once I stop pulling the trigger the weld puddle will grow a snake deal like the old fireworks for kids, it's behaving like there's no gas. The nozzle is dirty I've tried to clean it up but it seems like maybe a new nozzle is in order. What cause this type of malfunction?  Any answers would be helpful. Liner? Wire corrosion? Nozzle? Gas issue? See the large hole inside? Now I have to cut that out and get the weld in there correctly. But this is frustrating. Thank you welderskills JODY COLLIER

I'm doing some 1/8" 5052 & 6061 aluminum but welds and they are cracking at the beginning of the weld. I've been able to minimize the cracking, but not eliminate it. I know the cracking is caused by heat/cooling cycle, but I could use any help I can get to eliminate this problem.
