Not that you have specific need for thicker weld metal capability, but my Auto Arc MIG Hobart 130 mentions that using flux core you can weld a little thicker. I just wanted to mention though, I have only used with gas hook up AR CO2 and got 7/32 inch done even with the 0.024 solid wire with volts all the way up. I also have 0.030 solid wire but have not tried that yet or flux.
One thing I do is when in between welding leave the power turned on so the fan keeps running between welding to help even more cooling off. I like to make sure that I turn the volts all the way down and the feed to minimum too. I keep the nozzle trigger propped up somewhere so it does not inadvertently go on. When done I always take the tension off the wheel and that is useful also as I prefill the gas line and set the flow rate without wasting wire as it can’t move without wheel tension.
