Hi i am working on my van project, so welding body work steel about 1mmish i would guess. I havea rtech 180 using 5% gas and 0.8 wire. I get some nice spots then it will stop sizzling and a moulten ball will start forming and the weld goes bad. I have been finding i quite often end up with a small ball on end of wire even after a decent weld. Ive been using the rtech settings for 1mm butt so 1 on power and 1.5 on speed. Getting a bit frustrated trying to fix the issue and probably confusing myself. Where am. I going wrong?
