While visiting Harbor Freight yesterday, I bought some 1/16" 6013 welding rod. I am curious what kinds of things could one weld with it.
Sheet metal, boxes, body panels and the like. 6013 is generally considered a thin material rod, gives a nice looking bead with relatively low penetration compared to 6011 or 6010. You should be able to do butt welds on 24 ga material with no problems. Thinner stock may need an overlap.
Try 30 or 35 amps for a start. You want the amperage as low as possible but keeping both a consistent arc and reasonable flow out of the weld bead. A couple of issues in this range: many AC welders do not have a particularly high OCV (Open Circuit voltage) for low amperages. Makes arc start a pain. And you should assume that the amperage marks are pretty inaccurate. The TIG welding rule of 1 amp per .001" is not too far off the mark for stick also.
Set up a test strip of some THIN material (.049" or thinner) Run some 4" beads at various amperages, keep track of the amperages. I've found that these 1/16" rods have a fairly narrow 'sweet spot' that varies with each welder. I've run a bead so cold that it never even attached itself to the base metal, and so hot that the rod turned red and flamed out. Only 25 amps difference between the two!
I was once told that 6013 is the equivalent of an AC 6010 or P5 type rod. Is 6013 an oscillating rod? Or is it a 'dragger' like 7018? . . . thanks. *****************************************
6013 is 6013!
Three main classes of rod * basic - eg. 7018 * rutile - eg. 6013 * cellulosic - the xx10's and xx11's eg. 6010, 6011
They handle very differently
That is obvious to a beginner if you try all three - it isn't a "subtle difference" we are talking of.
Look up past posts on s.e.j.w. - perhaps using the Google news compilation.
They pretty well covered it. I bought some of that very rod recently at HF. But have not used it yet.
DC+ at even 25 amps seems to work for me with a Maxstar 140 for 1/16" rod. But I've never yet tried this particular HF rod.
If you attempt to weld metal that's too thick with 1/16" rod, it'll tend to just puddle up but not bond. That's the only situation where I've ever stick welded and didn't get a strong bond. I recently repaired a neighbor's mower deck with 3/32" 6013 rod at about 60 amps.
For pretty thin stuff I generally try 3/32" first. Then, if it burns through I go to the 1/16" rod.
Works for me.
Vernon, thanks, I bought this rod mostly out of curiosity and will give it a try. The price was very attractive (compared to McMaster).
