Hi all, Ive come across some new/old stock of cutting tips, about 50 of them, when I bought a pallet of some other non-welding gear. Can anyone please confirm if tips are made for specific machines or are some interchangeable? Apart from the size '0' on it I cant see any other marks or stamps to give me an idea who made them to confirm what they will fit.

Hi, the tips are an early model cutting tips, the later ones have a nut that is separate from the cutting tip. The 0 on it represents the size or cutting capacity of the tip. Do they all have the size 0 on them? I'm suffering a seniors evening so tomorrow I'll find my book on cutting and will be able to give more details if required.Quote:

Thanks Kryn, Yes they have a 0 on them. I'd be interested to see what they fit but not if its too much trouble for you. Given they are early model parts Im not sure if they are going to be of any use to anyone any longer.Quote:

Send them to the the scrapper. You will have far fewer problems with the newer type 41 nozzles which came in the following size designations. Ie the central hole is the cutting jet and is in mm measurement. Obtain and use a set of tip drills and with correct pressures set the nozzles will cut steel like butter in practiced hands.
The trick is to set the preheater flame to neutral which when observed will show the flame points as being slightly rounded. It they are sharp you will have the flame set too oxidising and will round over and melt the top of the cut edge. cut
6 = .6 mm cuts 3mm pl or so
8 = .8mm 3m to 10mm
12 = 1.2mm 10 mm to 25mm
15 = 1.5mm 25 to 75mm
Its from memory ok.

Hi, are they all in good condition like the one in the picture, it is important that the seating is not damaged, ie. the very base of it(narrowest end)
and the seat where the nut has a taper. If you want to sell them, I'll buy a few off you, as they come in handy for bits and bobs, I'll take some damaged ones also, if there are any. You could also try to sell them in the market place, if you don't want that many. For your information, they are a Type 30, that old, I don't have a listing for them, but I do have a cutter that will accept them.:2tsup:

As others have said, these are the standard cutting tips used by older CIG blowpipes. The "0" size was for sheet metal cutting up to 1.5mm (1/16'') IIRC. These tips were sized from 0 to 6 and fitted blowpipes up to and including the early Comet cutting attachment T828, which was only recommended for tips up to tip #3 (max 3" cut, ie 75mm). The hand cutting blowpipe T195 used all sizes of tips and would cut to 6" (150mm).Quote:

Thanks for all the info guys. I will be happy to just give these away to people if they want to pay for postage. Id rather do that then worry about all the consequences of selling older items. I will place some on the market place to give away and I will PM you Kryn.
