I know it's borderline but it was so cheap I couldn't pass it up. I'd rather not upgrade if I don't absolutely have to since it will only take money away from the rest of the project. After seeing what it can do it sure seems like it will be adequate, if only barely.
I will be doing a roof raise and will build storage boxes below deck, so it will be used.
Make/ Take some scrap pieces and practice welding the overlap or butt weld that you want to perform in place on a bench/ground,somewhere comfortable and play with it. Practice with the pieces vertical just like they will be on the final product. you can start flat for practice and work towards the upward positions you need.You want to Adjust the temperature and wire speed to where you get good penetration but not burn through all the way and coordinate both with your hand speed.
Whether overlap or butted up you actually want to see the two pieces melt together even if it means two passes? One to melt and one to cover for the overlap which means temperature settings and if you are butting the ends together then you want to burn through all the way and work that little keyhole from start to finish which means getting your temperature,wire speed and hand movement coordinated.
Sorry haven't had time to look at your thread very much?
Make sure your little machine is rated for the metal thickness you are welding and I am sure it will handle the ribs fine but when you get underside you might have some problems but we can discuss that when you get there.
Practice in a comfortable position until you are comfortable with your ability before you go for the real thing cause a position weld is always tougher than a bench.
Make sure your hood lens and gasket are good and wear your damn safety glasses when grinding.
Cause getting a sliver of steel drilled out of your eye while you have arc flash isn't the funnest thing to do.
Even if you wear leathers your still gonna get sparks down your neck and even though your boots are tied and your pants were over the top when you started your still gonna get sparks in your boots.
You will get used to it.
No longer than your ribs are and the guage of metal you don't need to stop because of a spark down you shirt are you could get some warpage from the metal temps if butt welding.
Hope I helped?
