Hello, I am starting to receive emails from LangMuir that my order might start to ship out in a few weeks.
- I am cleaning up my garage to make space etc. I will be installing a radiator to the compressor to help reduce moisture in the air even before it reaches the tank etc.
- I am already going through the assembly instructions to have a sense of what that process will look like. So far it seems reasonable.
- I have experience in designing stuff in Fusion 360, but I still have to try the CAM functions. I have a number of relatively complex 3D models made of flat parts that I’d like to be able to cut out. It does not seem to be too complicated but I will have to try. It looks like most of the LangMuir tutorials on Fusion 360 assume people design stuff as simple sketches so those are not going to help too much, but I guess the Fusion 360 forums and other videos on Youtube should help.
- I was able to acquire a “PRIMEWELD 60” Plasma cutter. It is still in the box, never used. I read a lot on this Forum about getting consumables and even a new torch from Mr. George. I am a little confused on this part.
I welcome general advice on what else I should be doing to be ready when stuff shows up.
About the Primeweld 60 and consumables, what am I exactly supposed to do there. After the initial setup and test of the system, I plan to cut a lot of 6061-T6 Aluminum 1/4" thick. I really want that project to come out good; should I get specific consumables for that material? Should I get a machine torch? 
I assume the Primeweld60 torch and consumables included in the box are good enough to try out stuff on scrap pieces.
Looks like you are ready…
So the included torch and consumables in the PRIMEWELD CUT60 are OK for 1/4" alu?
You get two 1.1mm/60 amp tips and electrodes with the plasma cutter. The chart in the manual calls for 45 amps and 60 psi of flow air pressure, I kind of like 50 amps and 65 psi.
Aluminum is one of the hardest metals to cut cleanly so cut your parts a little large for cleanup.

I’m with mechanic on this on aluminum is tough to cut not so much hard to cut hard to get a clean cut. I make a lot of tunnel stiffeners for mountain sleds and I ended up switching to nitrogen for when I cut them out to clean the cuts out.
What are you planning to cut out of 0.25" aluminum?
Yeah I haven’t checked the manual yet. Assuming I use 50A 65PSI, do I need specific tips and electrodes for best results? If so, can you suggest which one specifically?
As I said in a different thread, I plan to finish the edges (I like to have a slight radius) with a router table. Not sure if that will actually help the cleanup 
but it is also true that in my case the outer cut size is not critical, the location of the holes is.
In a different thread, they talk about machine torches. I am still not sure I’ll need one right away, but in case, what would be a recommended make/model for my setup?
The plan is sections to of a pergola or trellis-like structure. Each part will be roughly 4ft (curved) and 6in tall, bolt holes on each side. I hope this answers your question. May I ask, why did you want to know? Is aluminum not a common material to cut on CNC?
I was just wondering how complex it was. It isn’t uncommon to plasma cut aluminum its just messy. It sticks to everything makes a mess of your torch any slag is a nightmare to deal with but yeah it can be done.
Anything bigger or anything with a lot of cut outs I just send the file to a machine shop down from my shop to get it laser cut but everyone doesn’t have that kind of convenience.
