I have a small 90A 120V welder that I like for its ease of use, portability and convenience . However, he is very picky about what he will burn because in truth he is a little too weak. I've had no luck with 1/8" and was able to get good penetration with 3/32 7018 when I had a great power supply, but after trying them it was pretty obvious that this was my best rod for this little welder They burn nice and hot so I can get good penetration and the 6011 is great for spot repairs that aren't always the cleanest or cheapest.
