For those on classic view I thought I would post this update after trying some larger 3/16" rod.
Used this S7 200 amp Inverter welder again today to repair the stump guard on my rotary mower. Had an old coffee can with some 3/16" 7024 rod standing in there that has been in the shed for over 25 years. Ran a few beads with the 1/8" 7018 rod and cranked it up to 149 amps since it was sticking a little. Tried the bigger 7024 and it started welding just fine laying down a wide bead with no splatter, etc. Welded up all the cracks with it and it worked great with no shutdown. A few times it didn't want to strike an arc but figured out it was the cheap ground clamp. Once I scraped the ground clamp around on the stump guard, then it welded great.
