Ain't much you can't do with that except thin sheet metal. Looks great. Sears sold those for years. Very reliable. I'm not sure who built them, but don't think it was Lincoln. I've used Lincolns for over 40 years and ain't seen one like that.
You want to use 7018 rod in 3/32" and master that. If you go to the big box store like Home Depot they sell 7018 AC, but you want the straight 7018. The 6011 and 6013 is okay for dirty metal, but does not lay down a real great bead like 7018. Keep it dry and buy in small amounts.
And I wager welding 3/32" 7018 your duty cycle is going to be really good. You can probably weld continuously all day long.
You can weld some heavy iron with that sucker. Once you go below 16 ga you will have some issues.
