Ok, maybe this is a completely foolish question that I just dont know the answer to. Every time I look at a worn electrode on my plasma cutter, I'm looking at $20 or so hitting the trash can. Has anyone ever tried to fill in the worn out electrode?
Nah. I just pay the toll. The electrodes are pretty cheap, $15 or so for a nickel bag at my local supply store. Why do yours cost $20? Each? Are you referring to the electrode or the cone?
They are called consumables for a reason. Maybe we just add it to the cost of doing business. Can't see repair being cost effective in the long run. S**** it and move on.
Lincoln Pro Cut 55 electrodes are right around $100/5. Hats are only $30 or so per 5 hats/tips. I can find them online for less, but doesnt do me any good when I need them that second. I use a Hypertherm on my cnc, and the lincoln for hand cuts. The hypertherm is much better on burning consumables than the lincoln is. I have used both on my cncm and there is a reason the lincoln was demoted,lol. Just wondering if anyone has tried it?
My Lotos plasma cutter's consumables are 20.00 for a bag full. Had the darn thing 4 years now, use it almost every day, not a single issue with it.
Because Im thrify/tight***/cheapskate, whatever you want to call it. I also wash my dishes rather than buying new ones each time, same as my clothes,,,,, not TP though Not looking for answers like "they are consumables". Ive owned a cnc table for 10 years plus, I kinda have that pricing part down I just want to know if anyone has ever tried?
From what Ive read on the reviews on those,,,, you got REAL LUCKY. They seem to get the same great reviews as Central Electric I would destroy most cheap machines in a couple days as hard as we run that table of ours.
I build much of my own stuff. Sure time vs. money, sometimes it would actually be cheaper to buy parts. Some guys get it, some dont.
Nice to have, but not needed for me(or rather cost effective), same as laser. Right tool for the right job.
Then have you found out what the elecrode is made of? If you could find a fast way to m***-repair a few dozen tips, you might be better off not running the virgin one to the point where it was harder to repair? Meaning, catch it before the tips erode too much.
Didnt finnish my statement, Not only are the nozzles expensive,so is rebuilding the pumps and the slurry left behind has to be carried off as hazmat. 20 skins for a tip thats makes you money-not too shabby
Really has nothing to do with the original question. Was just curious, if you dont know, thats cool too.
Why ask the question if you don't want the answer ? You were told they were consumables and that is the way it is. There is really no way to restore them.
I think the situation is this,when they are"done" they burn slightly in the inner electrode tip resulting in additional clearance between the electrode and the "cap". This is the end and if filed you will just get more gap-correct? I feel like they are truly just the one time useage type products..... Mine is a Thermal DynamicsPk3,and they are not cheap nor readily available everywhere,so I wish you were on to a solution as much as you do. I feel that making sure your air supply is good and dry and not lifting the arc too high at end of cut and just releasing the trigger instead will extend life somewhat......I drag the tip right on the sheet a lot so maybe not maintaining arc distance at all is better?? just opinion here....
When I was researching a plasma cutter, one of the things I checked was the cost of consumables. HyperTec was the least costly, @ $45 per 5 sets. (electrode and cup) These are called consumables for a reason, they burn up/erode, there is no way to fix that. Buying the consumables is still cheaper than buying oxygen and acetylene for a cutting torch.
I have a CNC plasma table too.. Hypertherm 65 cutter. I can get 5 electrodes for $25 online. I literally go through 4-5x as many nozzles as electrodes. Tips are about $5 a pop too... Cost of having a CNC plasma table IMO.
To me, 1/8 inch drill bits for sheetmetal are consumables, too cheap to buy rather than to take the time to resharpen them, but I know lots of people that do. You guys really arent getting the question. Yes, I know they are consumables and they wear out. That wasnt the question. I do cut a lot on the table, and yes, thats figured in on my costs as consumables. AGAIN, wasnt the question. Yes, I have dry clean air and get lots of use out of tips,,, AGAIN, wasnt the question. The question is simple, and more curiosity, has anyone ever looked into fixing an electrode? Even if its not cost effective, not time effective,,,,, CAN it be done? Has ayone ever tried?
I'm a high school metal shop teacher. Our Thermal Dynamics plasma gets used a lot. Tip and electrode run $25 ish each time we change out. I can't see how an electrode could be restored but the Scottish side of me, tried to braze up a tip and re-drill the hole. Labor intensive and poor results.
I keep my tips going as long as I can by squaring up the edges, and keeping them clean with a wire wheel, but when the hole gets too big, they are junk, as you already know. Mine are made out of copper, so I would ***ume that TIG welding the hole closed with silicon bronze rod or maybe brazing the hole shut with silver solder would work, but you would still need to drill the hole. I am going to try to repair one and I will get back to you.
The hole is very small, and trying to drill that is very difficult. Not sure how you could do it economically or even accurately enough that it is improvement over the old worn out tip.
