will a harbor freight 90 amp gasless fluxcore welder weld 16 gauge floor patches

 

yes............................................... ........although depending on your skill level they won't look pretty

 

lol last time i used one i put a bullet through it that why i like my Holbart i tryed the littel harbor freight one for the trail but it burnt up so fast then that's why i shot it

 

Yes.. and it will do the job perfectly fine. Just make sure that the material being worked with and on is clean. And take your time. Any flux core wire is gonna look worse than a welder with gas, no matter whether you buy one that does the job, or spend WAAAAYY more money for not really any more welder.
