I agree with some of that. On cut quality though if you have the right machine and use it right there really isn't a whole lot of cleanup. I'm always amazed at the cut quality of my PM65 and if there's any dross at all on the metal after the cut a few taps on the edge with a hammer and it comes right off.
You have to set the machine to the material you're cutting.
You have to use a guide of some sort. At least I do.
You have to keep the angle of the torch consistently at 90 degrees (left to right) to the material.
And you have to pull the torch with a smooth steady motion.
If I do all the above the cut looks almost like it was sheared. I cut off some old rusty bolts with it yesterday that would have taken half a day with a hacksaw, or even a few hours with a cutoff wheel. It took me longer to put out a blanket and some protective cardboard than it did to make the cuts.
100% agree. Using it with a guide yields great results, especially when using one that is the proper height to give you accurate stand off height (or using drag tip).
APEowner- That is VERY likely. I'm sure much of my dissatisfaction with plasma comes from my inexperience, poorly set up machine, and unsteady hands, but I have still yet to see any hand cut plasma parts with a finish that rivals a bandsaw, jigsaw, or even cutoff wheels. Even many CNC plasma parts seem to lack acceptable surface finish (poorly setup systems, albeit) The cleanup I am referring to is the actual cut edge (slag should be a non-issue IMO).
Maxpower_hd- Love the plasma for cutting off brackets or really any de-construction. Sold my torch many years ago, although occasionally wish I didn't for other uses.
Like I mentioned, I'm just a hobby fabricator. I've probably only cut a few hundred parts with plasma and I know there is plenty of room for improvement in my skills. The intention of my original comment was only to express that there are many ways to skin this cat and, in my experience, plasma is
not the most economical method. But it sure is fun!
Maybe I'll try to find or start a plasma techniques thread to facilitate some collaboration. Lots of great minds here!
