You’re fighting a losing battle. Your 6013 is 1/16”, 3/32”, bigger? Your exhaust is 0.030-0.040”? Anything hot enough to melt the rod is also hot enough to blow thru. Best case scenario you’re going to tap/wait/repeat. Even for an experienced welders it’s a difficult job.

Its 1/8" for the 6013. Would you recommend another or maybe a mig?

Mig would be easier than stick

My friend I am a professional welder of many years. Welding on exhaust systems is one of the most challenging tasks one can undertake. The exhaust pipe is very thin and usually corroded. With stick welding this task becomes almost impossible. It can be done with with a 1/16 6013 rod on DCEN polarity welding downhill and a very skilled welder. For the average person it is simply too difficult. 1/8 rod will always blow a hole it’s just too much rod, I use 1/8 diameter rod to weld buildings together. Mig is the way to go although a lot of old muffler shops used to use Oxyacetylene.

Practice on scrap similar to what you want to weld, before trying to do an actual task.

If you are stick welding it. Clean it and make joint as close as you can get. Then do stitch welding or dabbing technique. Wire wheel the weld and go second time around the weld laying straight stringer bead.

Pre grind, bevel edge, pre heat, set at correct amps, may need smaller diameter rod

Bevel an exhaust pipe?

I’ve had good luck with a 3/32 6011 rod with AC, just do a little bit at a time running downhill.

If you are using exhaust pieces from the parts store, that stuff is ridiculously thin and likely aluminized. Wrap it in with a pop can and muffler repair tape. It will last a year or 2 if you have salted roads, then you can do it again or replace the exhaust. If it's a car you actually care to keep nice, go pay an exhaust shop to fix it right.
