Re: what\'s the max thickness a 110 wire feed can weld
We all know someone that claims their '67 Pontiac Bonneville will go places 4 wheelers are scared to go.
We also know, or hear of, folks that can weld 1/4, 3/8, 1/2 inch materieal with a 110 volter. If we wait long enough somebody will be bragging they do 2" thick material all the time.
Dribbling filler material out the bottom of the crack is not penetration. Whether it's Veed or not.
True penetration is when the filler material melts into the base material at least 1/3 to 1/2 the base material's thickness. The whole idea is that the base material on each side melts, almagomates, combines or merges together with the filler material, becoming one solid section.
Dribbling filler in the crack without melding (yes melding) the materials together isn't welding. Neither is using JB Weld.
110 volt welders just don't generate enough heat to do melt the thicker base materials - both sides, and the filler material, 1/8" is about max IF one is good with it.
Some folks claim they watch the puddle so they "know" it's penetrating - that puddle is the melted filler (wire), not the base metal.
But, don't believe me, or anyone else. Try it yourself. Test on 3/16" flat pieces. (Or have your local weld supply shop demonstrate one of their toys to you.)
Weld a horizontal flat weld, as good as you can for about an inch. Now break it - put it in a vice and hit it with a hammer - bend the pieces so they try to fold over onto the weld (in other words, hit it from the back.) Stand clear when it flies apart.
Take a look - the filler didn't break, the material next to it broke because it didn't penetrate into the base material. One side will probably look very clean, like it wasn't melted at all.
Now cut across that joint, or another made similar, and soak that part in acid, pool acid will do it. You'll be able to see how the crystalline structure changed but only on the surface. No real penetration, no wonder it broke. It's just the filler clinging to the base material like tape does.
Now take that weld and some more of the same material to a professional weld shop - ask him if he can do better with his real welders. He probably won't charge you anything, the laugh is worth it!
The toys are good for sheet metal and tacking things together to be welded with a real welder.
See for yourself!
It's your life!
