I have a basic gasless cored wire welding machine; Feed settings 1-9 and two volt settings 1 and 2. I always use volts at 2 and wire feed at 4 or 5 with Lincoln or Hobart wire. This wire took me some time to figure out I set it to 1.5 wire feed and to be honest it works amazingly well compared to a well known brand. So if you are having tuning issues I suggest reducing the wire feed.
