Please analyze my welds, if they are not "good" yet. This is Lincoln 100 without gas (if it matters), and Lincoln innershield flux wire 0.035.
While welding them, I can see that the high temp setting penetrates the re-bar deeper. With the smaller rebar (maybe half size the one on the pics) it almost went through the bar if I point at one spot for too long
At mid temp setting
At high temp setting
