Mines 7018 1/8'.I love those things for any kind of properly prepared
weld joint.....UNLESS,its some rusty old garbage with paint and who knows what all on it,and you can't get to it to clean it before welding,and the boss says.."come on hurry it up,this things gotta be done"....then its 6011.
Although i dont like to do stuff like that,sometimes its a "have to".And then i still dont like doing it.
As far as the 7018's getting a "corn" on the end making it hard to restart...try "flicking" your rod as soon as you pull off before it hardens on the tip.Just be cautious if your working some place where there might be
something to catch fire (cardboard,wood,etc.)That molten glob of flux could go anywhere.But really,those things should'nt be around somebody welding anyway.I try not to do any welding unless i know i'm gonna be around the rest of the day so i can keep an eye on my shop.I'd hate to lose all my equipment because a spark got in the wrong place and i left to go to town.
I've seen it happen many times.
