Chapter 2 cont:
This is a butt weld using the same 0.030" flux core and 1/8" wall square tube:
One thing you will notice with this welder is that it is very sensitive to the quality of wire used. I first started out with a couple spools of whatever wire HF sells. About 6 months into owning this welder I switched to some 0.030 Lincoln Electric flux core wire. This wire burned MUCH cleaner and hotter. Lesson here is that even if you only want to spend the money for a cheapy welder, don't skimp on consumables.
