I had a 33 1/2 watt ungar iron that had a chisel tip.  It finally gave up the ghost, but I didn't write down the model number.  It looked just like this one, but with a chisel tip.

Is there a list of Ungar tips anywhere or does anyone know the number of the one I'm looking for?

I found that 47 watt one on ebay for a good price.

Why not simply look up the model number of the cartridge in the handle--that will usually give you a selection of tips (and their model numbers) that you can choose from.

Huh?  I've looked up 4036 and that's all I get is the one shown.  I need the model number for the 33 1/2 watt version.  I can't make head nor tail out of the Ungar numbering system.

The one I'm talking about is an integral heating element and tip.  There are no threaded tips to it.  It looks like the one in the pic I linked to except instead of a round tip with a 4 sided pointed tip it has a chisel shaped tip.  No threads involved, all one piece.  I know I'm not dreaming, I had one, I just wish I had gotten the number off it before I threw it out.  But they may not be available any more.

David -

Weller purchase Ungar Soldering in 1996.  
Some old Ungar models were discontinued by 2000 (millennium), while others have been slowly discontinued since 2003.
Weller had to rework its entire production operations for RoHS compliance, which they did when they moved production to Mexico.

Ungar's old Edison screw-on soldering iron handles are sold/supported (heaters: 45, 33, and 23 watt), with an integrated soldering iron tip OR
with interchangeable threaded soldering tips.
You need to WATCH, as Weller has discontinued some slower selling parts (wattages, tips).

The Ungar 4036-S is a Stainless Steel Heater - 45 watt - 1100 degrees - Pyramid Tip
Arcade Electronics (Washington DC area) has that part IN STOCK for $34
http://www.arcade-electronics.com/Ungar-4036-S-p/ung-4036-s.htm

There is a 4036 Iron Clad Silver Plated Tip 50 W for sale on eBay for $19 from a Pennsylvania seller, right now.
eBay Item Number:  321085885701
===
You stated you desired a 33 WATT Heater / Tip.  HERE are those part numbers, with an integrated heater and iron tip.
These heater/tips are used with Weller/Ungar standard series modular irons SL325, SL335, SL345 and SL500

Modular Heater with Integral Long Chisel Tip, 33 Watt, 900°F: # 1233S
Modular Heater with Integral Long Chisel Tip, 23 Watt, 800°F: # 533S

The other Heaters sold in this series permit a screw on soldering tip (more flexible).

w9gb,

Thanks for that info.  It may be that the unit I'm looking for is no longer available.  The #4036 pyramid tip I obtained on ebay from a seller at a good price and it was like brand new and more seem available.  I'm quite happy with it, but the lower wattage one I had previously was not quite as hot and had an integrated chisel tip, not a screw on tip, so it had a large surface like the 4036, but not as large but a flatter surface to use.  The 1233S and 533S appear to be screw on tips, and I find them not as acceptable to the larger items I want to solder since they won't sink as much heat.  They're great for wires and regular items, but when I want to solder the end caps on a Rockwell/Collins filter, they just don't hold a candle to the large tips like the 4036 and the chisel tip I'm looking for.

I hope I'm not beating a dead horse here.  I do appreciate everyone's help.

NON-SEQUETER.

You asked for a LOWER WATTAGE (33 watt) and
desired a Chisel Tip that is Integrated with the Ungar Heater.
Modular Heater with Integral Long Chisel Tip, 33 Watt, 900°F: # 1233S

That is EXACTLY what part number #1233S is.
I HIGHLY suggest that you purchase more than one, IF this is the tip you desire !!

ALL-SPEC, listed as in stock.
http://www.all-spec.com/products/1233S.html

WASSCO, listed as in stock
http://www.wassco.com/Products/33W-Heater-with-Integral-Tip-900°F--Weller-1233S__UNG-1233S.aspx

Mouser even lists this part !
http://eu.mouser.com/ProductDetail/ApexToolGroupFormerlyCooperTools/1233S/?qs=xQzVGq%252bQa3HDpo59L3hMmMcBooygEUlv

The Ungar INTEGRATED TIP and HEATER selection (variety) in currently available
replacements are now limited, since the Ungar/Weller merger in 1996.
Arcade Electronics in Alexandria, VA should be able to assist you.

Actually I was looking for chisel tipped one that looked like the #4036 with the ceramic element, not the long metal element, but the 1233S may be about as close as I can get.  It will most likely work just fine.

Thanks.

That would be an Ungar 45 or 50 watt heater element (Ungar used ceramic for insulator due to high heat ~ 1100o F) with an Integrated Chisel/Screwdriver tip.

However, as I noted to you earlier, Fabrication/Production changed after Weller acquired the Ungar products -- some of this was RoHS compliance required, other was for easier production methods.  Weller has discontinued many Ungar ceramic heating elements.
These models are popular with the Stained Glass Industry.
http://www.glassmart.com/ungar_45_kit.asp

The Integrated Long Chisel Tip with a 45 Watt heater is part # 4033.
The Integrated Short Chisel Tip with a 45 Watt heater is part # 4039.

Arcade Electronics, near your QTH, has parts stock !

You will need the Ungar part number to inquire, Chester Electronics in Kenosha, WI
 has some Ungar inventory still left.

Yeah, Arcade, the last time I went into DC it took me 2 1/2 hours and that was just going in.  I try to avoid that trip if I can. I'd rather have the PO or UPS do it for me.

Here's what I've been looking for, a chart of 'Heater guide and tip selection' and 'Integral tip selection'. Now all I have to do is find a 1233-S, 1236-S, or a 1239-S.  I'm not sure which one I had but I think it was copper so it must have been the 1233-S.

It looks like the 12 signifies 33W, 5 is 23W, 40 is 45W, and the other numbers seem to be mixed up.

I found some 1239 Armco Iron 42W integrated heaters for $9 each on the eflea, they both work and I've got them tinned and ready.  They had a bit of corrosion on the threads, but nothing to worry about.  I still need to get a couple of 33 watt irons.  These are not on the chart I had, but couldn't pass them up at that price with free shipping.  I think he's got a bunch if anyone wants some.  I'm not sure what Armco means, they are probably not copper, most likely silver plated iron.

I tend to use these things with a lamp controller to keep the heat down, otherwise they seem to burn up pretty quick.

Hey OM
Just a caveat on the Ungar ceramic elements to make them last longer put a full wave bridge rectifier in the handle for sum reason pulsating DC makes the element last longer.
Alas I used to make a living selling Ungar Irons in the ceramic elements the last 2 numbers were the wattage like 23, 33, and 45.
The integral  units lasted longer cause they knew you had to toss the whole unit when it died.
I had the heating integral unit with chisel tip I used to solder LMR400 shield to PL259's

Ray,

That is a good suggestion.  The old ARRL handbooks of the 1950s to mid-1950s suggested that same approach (pulsed DC).  Model Railroaders did that same trick for low speed with locomotive motors.

When solid-state SCRs and Triacs (such as Q4015L5 or the NTE6020) became available in late 1960s, the ARRL Handbooks suggested their usage (120 VAC commercial light dimmers) for line voltage soldering irons.
