Old Smith and Purox torches

admin

Following up on my previous post about the old Smith regulators, here's some pictures of three Smith and one Purox torch and tips.  I just bought all of these with the regulators and five big bottles and a couple of nice heavy-duty carts.  I cleaned them up slightly to help find model numbers, but they are still a little grungy.The Purox is marked W-200 and the tip is CW-200.  This one doesn't appear to be as old as the Smiths and is in better shape.  The medium-size Smith is tagged No.8 followed by a serial number.  The small one has apparently been brazed near the fittings and is not marked.  The big one also doesn't appear to be marked, other than "Smith Lifetime Guarantee".  The tip on this one however appears to be stamped A883, but the A really looks more like an upside-down V (no line across the A).  The tips are clearly marked at least.If anyone can give me some hints about the age or model number of the big Smith, I would appreciate it.  It would make it easier to get parts if I knew the model number.  Thanks.  More pics below.

Reply:Always take the cutting torch tips out when posting so their bases can be seen. The big Smith takes an LC tip. You can also use an American Torch Tip adapter which I have on mine.http://weldingweb.com/vbb/showthread.php?t=49243I think there are some Smith heating tip comparison pics in the Oxy Fuel thread.
Reply:I can only help you with the Smiths.Your smallest Smith torch is a number 2 and your medium Smith torch is a number 80 (both of these are id'ed in my 1941 catalog).  In my 1957 catalog, both of these are listed as obsolete, parts still available, and the number 2 is called the "Aircraft" and the Number 80 is called the "Autocraft."For your biggest Smith torch, I believe that handle was made somewhere in the gap between 1941 and 1957.  In the 1941 catalog, there's a similar handle and identical cutting assembly, just called the "Smith Lifetime Welding Torch Body" (part number F-7G) and "Smith Lifetime Cutting Assembly" (part number G-452A with one tip and wrench)   The handle isn't the same - there aren't the full-length ribs on it like yours has.  The cutting assembly, as I mentioned, is identical.  In the 1957 catalog: There's an obsolete F7K handle pictured, with the correct ribs on the body, but the knobs aren't correct.  The cutting assembly is listed as obsolete, and is called a G450B with 80 degree head or G450C with 90 degree head.  There's no mention of the lifetime warranty.I have a pre-1941 version of this handle, with T-handles instead of knobs to open the valves, and the same lifetime cutting assembly that you have.
Reply:I've added a cutting tip picture which might help.Thank you very much for the details and research.  Very interesting and helpful.  On the tag of the medium torch I only see No.8 followed by 407681 which I assume is a serial number.  I wonder why they didn't stamp No.80?  Or maybe the 0 is just not readable on mine.  I did notice at the head of the big cutting attachment a G4 but unfortunately the rest of it is gone due to vise marks.  So this definitely is in line with your G-452A.

Reply:Thomas, farmall is right that you'll be using LC-style cutting tips with the big Smith.  They're a little hard to come by, which is why he recommended the adapters and different style tips.Although both of my catalogs refer to that medium handle as the No. 80 (the cutting attachment which you don't have is called the No. 800), it's possible the earliest versions were called the No. 8.  I'd be interested in knowing whether these old two-tube cutting assemblies and their handles are still rebuildable under the lifetime warranty, or if parts are NLA.  Mine are wall-hangers.Any comments, OADoctor?
Reply:They would likely be REPLACED under Lifetime Warranty, so you'd lose the old torch.Test them and put 'em to work. Warranty is for broken equipment. Check here if you need o-rings etc. Nice exploded views.http://www.sealseat.com/prod01.htm
Reply:I contacted OAdoctor yesterday evening, and he replied quickly about the regs and the torch.  He said any problems would be covered under warranty (so I suppose at least some parts would be available), but as you mention this does not imply a restoration.  He said they've been really busy and he's not been able to keep up lately on the forum, so he might not be able to chime in.I did briefly fire up the big one last night (I didn't detect any leaks) and it seemed fine except I can hear a buzzing sound on the oxygen side.  Changing the O2 flow through the torch caused the buzzing to increase, so I didn't play with it too much.  I'll most likely send it in along with the regs since that would at least ensure correct functionality.  I'm not sure if o-rings and seals are covered under warranty, so your link will probably come in handy.  There are sure a lot of parts listed in the Smith catalog.Thanks for the advice on the adapter.  Looks like that's a good way to go.Hobart Handler 210Lincoln AC-225Smith Torches/Regs
Reply:I just noticed that atlweldingsupply still carries a few LC-style tips including LC4-0, LC6-5, and LC6-4, but they don't explain the difference between those.  The adapter could still be handy though.I'm also needing to get a set of flashback arrestors which will fit the three smaller torches.  Are these "A" fittings?  The ones I have are the larger "B" size.  Or maybe there are adapters available?Hobart Handler 210Lincoln AC-225Smith Torches/Regs
Reply:The small torches are A-fittings. ATL can guide you to adapter and tip choices.I just telephone them when I order.
Reply:I've tested all three Smith torches (after finding some B to A fitting adapters) and so far so good.  The buzzing sound I'm hearing I think is coming from my check valves.  These were from my cheap HF set and they are advertised as being flashback arrestors, but they are only about an inch long and are labeled "check valve".  I've used these a lot with my HF torch, and I've always thought they were flashback arrestors, but I don't think so.  I was planning to buy a set of arrestors for a spare hose I have anyway, so I'll get two sets instead.Can someone explain the Smith LC tip numbering system?  I've googled quite a bit and haven't turned up much.  I've found a pretty good source of LC tips, but they are labeled LC-1, LC-4, LC-6, etc, along with sizes 1, 2, 4, 6, etc.  I have a general idea of what the sizes mean, but the number after the LC is confusing.  I first thought the LC-x number indicated the number of preheat holes, but why would there only be one in the case of LC-1?I haven't ruled out just using the LC adapter fitting, but I'm not sure how much I'll need to use this big torch so I don't anticipate needing more than a couple of tips for it.Hobart Handler 210Lincoln AC-225Smith Torches/Regs
Reply:Ranges are approximate. Find the number on your tip, make some typical cuts for your intended use, then go up or down by two steps (if) needed because there is considerable overlap."Smallest plus one" and "smallest plus three" sizes is a good start for most torches. http://www.americantorchtip.com/cata...smID=OSMTS0300I'd get a 0 and a 2 for starters.
Reply:My 1957 catalog has a list of LC tips.  This will be the only help I can give you, so I hope it's what you need.  The numbers mean different things depending on the tip style.  I know some of Smith's earliest LC-style tips didn't have the "LC" stamped in them, so you could have a tip that just said, "0-4".Assuming you have a number like this:LC0-4.  This is the standard oxy-acet cutting tip.  0 is the size of the tip.  4 is the number of preheat flames.  Available in sizes 0-4.LC0-6.  Same as above, with 6 preheat flames, called "heavy preheat."  Available in sizes 0-6.LC11-6.  Same as 6-hole tips above, except 7/16" longer.  Available in sizes 11-16.  Size is the first number as above.LC21-6.  For cast iron cutting, "extra heavy preheat."  Available in sizes 21-26.  6 preheat holes.LC31-0.  General purpose oxy-propane cutting tip.  All end in -0, and sizes are 31-36.  "Heavy preheat."LC64-0 and LC66-0.  These are oxy-acet scarfing/rivet washing tips.  6 preheat flames, "extra heavy preheat."LC61-0 and LC62-0.  These are oxy-acet sheet metal step-type drag-style cutting tips, "very light preheat."  One preheat flame.LC51-0 amd LC52-0.  Rivet cutting oxy-acet tips, 3 preheat flames.LC72-0 and LC74-0.  Oxy-acet gouging tips, "heavy preheat."  These are similar to our curved gouging tips of today.  6 preheat flames.LC84-0 and LC85-0.  Oxy-acet, 4 preheat flames.  "Riser Cutting Tips for removal of gates and risers from steel castings.  Extra heavy preheat."
Reply:I bought a older Purox welder type 35, W437311, the only I.D. I could on find torch body, also the cutting torch has # 31 ca stamped just under ox. lever.Anyone know the age of this torch? I am looking for some welding tips, I got a good #1, but #5 seems to spead out way to much. The hole looks round enough and I have tryed cleaning it. , but doesnt help. I am new at welding, any help thank you
Reply:Heres some photos of that Purox type 35 welder, notice the tip and torch body have the hexagon shape Attached ImagesLast edited by Bluerider; 06-14-2012 at 02:38 AM.Reason: photos
Reply:Ebay would be where to look since it's fairly old and no longer produced. I don't have a date range offhand.Look for tips which have the same base as yours. I'd keep the torch even if you get another. Torches don't get jealous of each other.There is a steady, small stream of inexpensive Purox/Oxweld/L-tec/Linde/Prest-O-Weld gear on Ebay. I'd keep an eye out for torches WITH tips and not just look for tips for what you have.If you get torches with tips, they certainly don't need to be the same brand as your current setup. Keep an eye out for deals. There are plenty of OA threads for detailed info.
