![]() Grind the ends of the pipe at an angle, so that when the two pieces meet, it creates a 'v' to weld into. Neither can the piece of metal that your ground is attached to, which will by the way be located as close to the weld as possible so the current stays consistent. The longer wire sits, the more moisture can attack it.Ĭlean the area to be welded to a point where you wonder 'can it be TOO clean? No, it can't. Go buy some Lincoln wire from a place that sells a lot. Throw your harbor freight wire in the trash. An experienced welder can bend this rule, but an experienced welder is also less likely to have poorly fitted pieces in the first place. This means trial and error, or more math than I am willing to do, so often trial and error. There should be virtually no air gaps between properly fitted pieces. You are NOT a welder, so you need to add a level of safety, and sleeving and plug welding is the way to do it.įit your pieces correctly. Search the welding forums to learn what this means, and don't ever ever skip these steps. I must preclude my suggestions for better welds with a stern 'you shouldn't learn on a bike'.

This is meant as a guide to hopefully give you a better chance of having decent useable welds the first time you try. These tips are in no particular order, and some are more important than others. Yours might be the same or it might be wrong. Maybe that partially stems from my personal view that if something cost 4x as much and doesnt perform at least twice as good, then its fuckin dumb to buy it. Ive used Lincoln, Snapon, Miller, ESAB, and many other 110v welders and would still reach for the HF if given a choice. I personally cannot recommend a better 110v flux cored welder at any price. A thread in the projects forum prompted me to give my humble advice on using the 90 amp Harbor Freight welder that many people end up buying for a first machine. Although welding is not my specialty, I weld a lot.
