I tried this today outside the shop using an old metal cutting chop saw. It cut fast and left a fairly nice surface finish. It's one thing to hear you say how important it is to do cut and etches. It's another to actually do it and view the results. Example: I was doing beads on plate, and all came out okay except for one. I was to high up on the adjacent bead and I could see the error by looking at the weld penetration.
100% the proof is in the pudding. Seeing the results with a cut and etch will make a better welder out of everyone. I definitely have been surprised at a lot of things I have found in tests I have done for the channel lol. Even had lack of fusion with tig which is hard to believe but without testing I would have never known lol.
You’re welcome. It’s cheap to do and easy. Definitely worth checking out to see how things look. When I get into short circuit MiG there will be some very interesting test results 😀
Hi Greg, thanks for showing the full process, including the polishing steps and tools used. I agree, Jody at 'weldingtips and tricks' is great. Look up the funny story telling episode 'Stick Welding Tips from Bubba'. Lol.
So I have a 3.0 and 4.0 battery. It’s surprisingly pretty good for a 12v tool. It works best with die grinder bits or mini scotch brite pads. Mini wire wheels it works poorly for. I also have the 12v band file and that eats the battery far waster than the die grinder. I find that it will last as long as the 18v die grinder with a 5.0 battery, the difference it the 18v I have cuts faster.
I had no idea so I did some research. It seems ferric chloride is used in some cases, that would work. Cupric chloride is also commonly used, however I have no experience with that chemical and I am unsure if it would work. I have a feeling it probably would. I tend to use naval jelly because it works pretty good, is available everywhere, and has a funny name lol.

I never saw that one, funny video. It might actually work in real life 😅.
How is the battery life on the Milwaukee die grinder?

Can i use the radishack pcb etching solition? Ive had it for years.

i wonderif muriatic or mulickt acid will work
I bet muriatic would probably work, I haven’t tried that. As long as the plates are warm and fairly polished cheap naval jelly works real good 😀
Hello, what is the solution that you put on your weld?
It’s naval jelly, sold everywhere that has chemicals 😀
