Hi
Lads
Got a new toy to play with

I can't watch the video right now as I'm on a client site - but they are rather brilliant things, aren't they?
I bought an old transformer based Cebora (partly because I don't trust this newfangled Chinese inverter stuff, and partly just because I like the heavy duty), it's brilliant. Cuts 10mm steel like it wasn't there. Cuts aluminium too. Shame it deosn't cut wood, really, it'd be perfect if it did...

Hello Doubleboost
They are great machines,BUT if not fitted with low air pressure cut out can cost a fortune.
If it has not got one fit one,
Same goes for an air dryer fitted on the air input. (From the clip would suggest is to small fit another in line.)
Only set the cutting current to just do the job, over current uses the electrodes quicker!
To cut non metals lay a sheet of metal on top up the current and try it.
To cut rod or tube make up a hand rotating chuck and keep the torch still, cuts much neater and to the centre.
Have fun

Mine has the low-air cutout, it has a regulator fitted to the back to keep the input pressure at the right place. No dryer though....
I only have two power settings: HIGH and HIGHER :lol: I like the idea of the chuck...

well dun as per john :thumbup: :thumbup:

Any decent welding supplier

Another great video John, thanks...you have just cut up what would be my whole months supply of metals :dremel: :clap:
Lyn.
PS: John.. is the spindle assembly on the 626 easy to pull apart and refit?
Ta. Lyn.

Hi
Lyn
R-Tech supplied the metal that I cut up
The spindle is a straight forward job (I think I have some pictures )
The bearings in mine were very good but the grease was shite

Thanks for the link John, I've ordered the mask.

John, don't go paying for that cutter . You've earned it ;)
(Honestly, i had more expensive freebies after reviewing them :D)
Another great video, i was particularly taken by your neighbour's long johns - must get me self a pair8-)

Andrew,
You have ordered a mask from a company that states "doesn't post to South Africa" -seems a bit discriminant to me. (Shame on you)
:lol: :lol: :lol:

That thing does look handy. Especially with the circle cutter.
How would it fare cutting things with a non flat surface? Like castings or extrusions.
Oh by the way the video didn't turn up in my youtube feed. Maybe it's something wigging out on my end but you might've forgot to send it to subscribers.

I used mine to cut the rusty frozen nuts off a bunch of studs (hmm, now there's a sentence that could be misinterpreted :bugeye:) that were holding a cast iron exhaust manifold on. Managed to do it with minimal damage to the manifold, although the plasma would cheerfully cut that I'm sure.

Hi John
Very well presented, that is a very attractive piece of equipment, already beginning to covet it.
Cheers David

Neat. ,much more powerful than my $300 chinese one. CONSUMABLES thou are $40 for 250pc set for mine, was more before I put the CHEAP chinese torch on it. THE miller I had I could not afford them, I'd use a saw.
TORCHES change out if you get tired of the "best ones" in yours and want to be cheap. it is either a 7 wire, or a 2 control wire torch.
Pattern cutting, 2'x2' barrel sized cutter table is perfect for a small shop, Mine started out as a torch. now a plasma pattern. Now on a roll-about table instead of a barrel to catch the sparks. (sparks and metal dust are on floor now)
I have a $100 cnc attachment for it drew up , will share when it works out into reality.
Adjustable Manual circles with swivel, ball bearing "drawer sliders for saw cuts". I used to clamp a ruler on the pattern arm and trace it.. I normally just drag cut beside a ruler if I am in a hurry..
https://www.youtube.com/watch?v=FsgmJW2uX7s (https://www.youtube.com/watch?v=FsgmJW2uX7s) The circle cutter in action with close up of radius adjustor.. a simple cantilever swivel, the most important thing is to have the torch center under the tracer center, have the whole shebang level so it stays the same height over the cutting table. Grate is just flooring from a mezzaline floor. A drop, left over piece.
BY the way, I have no respirator?? my iron content of my blood has been off the chart since I have been cutting with my plasma???? WTF??

John,
I have been watching your videos with interest, this thread has come at the wright time.
I am about to buy a plasma cutter, just one question, have Plasma cutters with built in compressors got an advantage (apart form the obvious as having its own air supply) over the cutters without.
John W
-
Hi
John
You have hit the nail on the head
Having its own air supply makes it truly portable
This is the only possible advantage
John
-
I think the other way to look at it is if you have a self contained unit comp /plasma ,if one goes tits up
And has to be repaired,the whole unit has to go,so no comp /or plasma .
Worth thinking about !
-
ref "Plasma cutters with built in compressors"
Self contained compressor makes it portable.
My Son in Law a Lloyds Reg Welder was able to do work quickly and cleanly on large boats while afloat using the ships generators only.
He maintains the built in one are perfect for mobility, but prefers the more standard one for shop use.

Hi there, John,
That's a very impressive and useful machine.
Have you tried it on cast iron?
-
Nice one John, keep em coming.

I will chip in my little bit of experience with plasma cutters re built in compressors.
I convinced my bosses to invest in plasma and do away with the oxy-acetylene equipment, so first off we brought a draggun 35c? and it was fine except it used a lot of consumables and I noticed when it was starting there was plenty of moisture in the air flow probably imho the reason it used consumables so much.
now we have a cutmaster ?? which requires a seperate air supply and right away I noticed much (by a long way) longer consumable life and even a slightly better cut but that could be down to it being a tad more powerful than the draggun, not that I ever used either to the limits of their capabilities.
So even though you would get better portability from a self contained unit I think it comes with a cost.
-
Thanks for your quick reply's
John,
portability's not really necessary, so compressor less will save a few green beer tokens I suppose.
jb3cx,
I think whether it has an on board/separate compressor you are still going to have the same problem if one of the functions goes belly up you wont be able to use the cutter.
Pete W,
I haven't bought a machine yet just testing the waters.
shipto,
that's interesting could it have been that the on board filter was not big enough, that is worth taking into consideration when I buy my machine.
Thanks John W
-
Clean air is essential with plasma cutters I use 2 filters as far away from the compressor as possible; I would go for a plasma cutter and separate compressor, not as portable but think the plasma cutter would be better quality plus you can use air tools as well :scratch:
-
mfletch,
Seems consumables suffer from moisture so with shipto and your hands on experience I think I will go with a separate compressor, my air system already has 2 filters so would be easy to add another for the plasma cutter.
