The cutting hardware has all to one to the junkyard many moons ago my friend. Pictures are all you have left. I tried to find an illustration in my text books in vain.
Why bother if you can now get a cheaper ,faster and cleaner plasma. Oxy acetylene/lpg has its place but not in this particular circumstance.
Even I have been dragged kicking and screaming into the modern age.

Mick,
What are you looking for specifically? Rather than be too general it much better to specify on what you wish to acheive,or if anybody who wants to make a post.

Grahame,
not exactly sure, but I spotted the post and noticed the "to be continued" without any further posts from you. Perhaps gas pressures would be helpful, plus a trouble shooting guide, ie if it looks like this you're doing this wrong etc.

if you're cutting thick plate warming the underside first, makes a big difference.
If you have trouble getting started when cutting round bar, hold a thin piece of scrap to the side and you will find you can start you're cut much easier.
and the most important thing is to hold the torch firmly,don't try to strangle it as this will only make your hands shake, relax it aint gonna bite.Cheers Fred

Gday Mick
A fresh thread is posted.
I have been playing around trying to do a photographic thing, but the cant' get pics right at the flame.I don'tseem to have the right equipment.
I would appreciate if any photographic tecchy type could clearly photograph the hand held torch head showing a macro shot neutral flame flame with the blue cones just above the plate surface.
I have searched and Googled big time and can't find any illustrations to suit the power points

My camera is at work, but I'll bring it home on Tuesday and do it, if no one else can do it sooner.

Tony,
We purchased one for school thinking that it would be easier for the students. Our experience is that the low pressure regulators required for effective use were extras.
The vendors did not give support one could normally expect.The did not follow up on phone calls or emails very well at all and generally did not seem to be supportive of a customer who had spent a good deal of money with them.
We had trouble matching thesupplied American Gas thread to to Australian code regulator. Our p/time teachers assistant whose other job is as a licensed repair man for Oxy Acetylene regulators and torches.
Had it not been for him we would have not got the unit operating at all.
Yes it will weld aluminium and so forth,but honestly A Tig does the job better.
Four years down the track we are back to using the normal cutting torch and $600 wasted sits unused at the rear of a storeroom.
Thats is our experience others may have fared better.The unit does not seem to be vigorously marketed here as I don't see mention of it too often.

My BIL talks about a trick he does where he heats up the edge of plate and then pushes the oxygen cutting jet and starts cutting then he turns of the acetylene and keeps cutting - he says if you do it smoothly and slowly enough it will keep cutting! Apparently the heat of the burning metal is enough to keep heating the metal ahead of it - kind of like a metal firestorm!
