Re: [Emc-users] Plasma torch for cnc machine

[jeremy youngs]

hypertherm = expensive consumables. i have a friend with one and he borrows
my harbor freight 40 amper because my consumables cost 12 bucks to replace
his are 50. i am leery of h.f tools especially at 650 bucks but alas after
8 yrs of ownership i think this is the best non commerecial plasma cutter
available and definitely the cheapest to run . the torch is a high quality
trafimet. my friend the other day told me if he could sell his ( original
cost of 1200 bucks ) for what an hf unit costs (650) he would do it
immediately. as to the esabs in  a similar price range you get no pilot arc
feature and again high consumable costs. i pondered the purchase for about
2 months going to hf 3 times and reviewing the product. i believe this to
be the single best buy at harbor freight period. yes im a bit proud about
this but after 8 yrs my concerns are no more and this has proven to be an
excellent buy and ovbiously i would not hesitate to recommend one or
replace mine with another if it gave in the ghost tomorrow with another
just like it . well thats my .02 hope it helps

One of 3 LinuxCNC users in my country that I am aware of, owns Jasic plasma
source and he recommended them to me.
I personally do not yet have any experience with them.
See few messages back in this very same thread - Dave wrote that it works
quite well.

[Emc-users] Plasma torch for cnc machine

[Roland Jollivet]

Have a look at this . I don't
know if it's just good advertising, but I'd like one..

You also need to be aware of the 'start' methodology. HF noise etc.
But from what I've read, you won't go wrong with Hypertherm.

That is very simple - replace the manual button with something that is
controlled by cnc controller - either a relay switch or anything else
(optocoupler etc), depending on what kind of signal is going through those
wires. In the welding robot there was a "manual" MIG welder, which  had 8 V
AC in the control button wires, so it took 2 output drivers on Mesa 7i37 to
handle the "AC" part, while 8 V was much less of a problem.

Viesturs,

Looks like you need to take apart your old manual torch head and attach 
this head.  I see two setscrews in the back of the automatic torch head 
which are likely cable clamps for the power cable lead.

I have a Cut 60 plasma setup which works ok.   Cuts 1" manually without 
a problem.

Looks like the Cut100 requires 3 phase power.

Dave

Yes i'd agree it does look not capable of 100A , however they do work 
quite well , Although i'd realy rate them
at about 60A Max , i have 2 running at 45A and they work fine

i have been tempted just to tear the case off and make my own to suit 
the z Axis and make it more integral to the machine
but not got around to it as yet .

i'd class these as a Hobbist level , rather than a proffesional torch 
capable of many hours

[Emc-users] Plasma torch for cnc machine

[Viesturs Lācis]

Hello!

I was thinking about a plasma source like this:
http://www.ebay.com/itm/251355364995

It is supplied with a torch that is meant for manual operation - the
problem is that it is angled, not straight, which makes it not only more
difficult to mount, but also takes up more space and also does not look
that nice.

I found a torch, whose description says that it is suitable for the
previously mentioned plasma source:
http://www.ebay.com/itm/151167833644

The second picture of that listing seems somewhat suspicious - I do not
see, where the power cable lead should be connected. There is one small
connector visible, but that certainly is not capable of 100A current.

I would appreciate any advices or links, how other plasma users have solved
this issue.
Thanks in advance!
