Short answer: The Carlisle Black Widow and the GTT Delta Elite are both high-end bench torches priced near each other, roughly $2,207 to $2,575 as reference figures, but they solve the top-end problem in opposite ways. The Black Widow is about configurable flexibility: you choose its center fire from four types (pre-mixed #3, pre-mixed #5, surface-mixed “Artistic”, or surface-mixed “Hi Oxy”), and the whole head sits on a base that turns a full 360 degrees and adjusts vertically. The Delta Elite is about layered refinement: one fixed, deeply developed Triple Mix flame, a 57-jet surface-mix torch built around a 7-jet Lynx center with 50 outer jets in three rings. Buy the Black Widow if you want to tune the center-fire character to your work and want a base that repositions around large or standing setups. Buy the Delta Elite if you want GTT’s single, refined layered flame and a torch sold as both a four-stud bench and a hand version.
If you are still mapping the larger decision, start with the complete glass torch buyer’s guide; this article zooms in on these two torches specifically.
The Carlisle Black Widow: a selectable center fire on a rotating base
The Black Widow is a 4-inlet bench torch with 2 stages, and its defining feature is that the center fire is a choice you make, not a fixed part of the torch. Carlisle offers it in four center-fire variations: a pre-mixed #3, a pre-mixed #5, a surface-mixed “Artistic”, and a surface-mixed “Hi Oxy”. A premixed center gives you a tight, hot, candle-like pinpoint; a surface-mixed center stays gentler and more adjustable. That is a real fork in flame character, and the Black Widow lets you pick the branch that matches how you work. Carlisle also documents a Centerfire Add-On, so the center is treated as a swappable element rather than a permanent casting. Source: Carlisle Black Widow.
One thing to be precise about: choosing the center-fire type is a purchase-time or add-on decision, not a knob you flip in the middle of a session. You are selecting the torch’s center character when you configure it, and swapping means fitting a different center fire, not turning a valve. If mid-session versatility from one head matters more to you than picking a specialized center, weigh that carefully.
The other half of the Black Widow’s flexibility is physical. The head adjusts front to back, tipping almost straight up or straight down, and the whole assembly turns 360 degrees. The base adjusts vertically, which Carlisle frames for a standing artist or for larger work where you need to bring the flame to the piece rather than the piece to the flame. For sculptural work, murrine setups, or anyone who does not want to stay pinned to one seated angle, that adjustability is a genuine ergonomic tool, not just a spec.
The GTT Delta Elite: a fixed 57-jet Triple Mix layered fire
The Delta Elite takes the opposite path. It is a 2-stage, 57-jet Surface mix torch, and the layout is fixed by design. At its heart is the 7-jet Lynx center fire, which is itself a standalone GTT Triple Mix torch, surrounded by three rings of outer jets that add up to 50 jets, for 57 total. You are not choosing a center; GTT has already chosen it, and the entire torch is engineered around that one flame. Source: GTT Delta Elite.
That flame is where GTT concentrates its effort. GTT describes the Delta Elite as capable of many flame types, from a soft bushy flame to a hard driving flame, spanning fuel-rich reduction, neutral, oxidizing, and over-oxidizing chemistry. GTT says its patented Triple Mix approach surrounds the fuel with oxygen and then injects oxygen directly down the fuel stream, which the company says burns the fuel more completely for a hotter, cleaner flame. Those are the company’s own framing of how the torch behaves, not measured figures we publish; treat them as GTT’s claims and confirm the character against your own bench. Source: GTT Triple Mix.
In typical use, the Delta Elite comes standard with a 4-stud manifold for setup flexibility, and its normal operation uses a foot pedal to bring the outer fire on and off while the outer-fire valves stay preset. So the range you get is not from swapping parts; it is from developing one deep, layered flame and modulating how much of it you are running.
Center-fire philosophy: swappable premix-or-surface vs one layered surface mix
This is the core of the comparison. The Black Widow asks which center fire suits you and lets you specify it, premix or surface, tighter or gentler. The Delta Elite asks nothing; it hands you a single, highly refined Triple Mix flame and expects you to learn its full range.
| Consideration | Carlisle Black Widow | GTT Delta Elite |
|---|---|---|
| Center fire | Selectable: pre-mix #3, pre-mix #5, surface “Artistic”, or surface “Hi Oxy” | Fixed 7-jet Lynx Triple Mix center |
| Jet count | Not published in the catalog | 57 total (7 center + 50 outer in three rings) |
| Base mix type | Surface mix outer, with a premix or surface center by choice | Surface mix (Triple Mix) throughout |
| How you get range | Configure the center at purchase; add-on center fires exist | Develop and modulate one layered flame |
| Mount | Bench only | Bench or hand (four-stud bench standard, separate hand version) |
The trade-off is flexibility against refinement. If you want to dial the center character to a specific kind of work, or expect that preference to shift, the Black Widow’s configurability is the point. If you would rather own one thoroughly engineered flame and put your energy into mastering it, the Delta Elite’s fixed layout is the point. Neither is the “better torch” in the abstract; they optimize for different owners. For the underlying premix-versus-surface distinction, see surface mix vs premix torches.
Oxygen and gas supply: what each maker publishes, and what it does not
Here the two makers differ in what they put on the page, and that difference is worth stating plainly rather than papering over.
GTT publishes an oxygen figure for the Delta Elite: our catalog records ~30 LPM as the largest-usable-flame estimate. Oxygen is a rough sizing input, not a precise buying spec, but at least you have a number to size a concentrator or tank against.
Carlisle does not publish a working-flame oxygen figure for the Black Widow, so our catalog leaves it unrecorded, and we will not invent one. Carlisle’s page does list approximate consumption ceilings of around 80 CFH propane and 448 CFH oxygen, but per our convention those are capacity maximums, not working-flame numbers, the same way the Carlisle CC family’s “maximum cubic foot per hour” figures are ceilings. Do not read the 448 CFH as what the torch draws in normal use. Carlisle also lists recommended pressures of roughly 3 to 5 PSI fuel and 10 to 25 PSI oxygen, and the Black Widow may run oxygen with propane, natural gas, or hydrogen. Source: Carlisle Black Widow.
Editor’s note: figures here come from each maker’s own pages where we have them, and are labelled as estimates where they are ours. The Delta Elite oxygen number is a GTT-published estimate; the Black Widow’s working-flame oxygen draw is not published, so we do not state one. Always confirm current specs, pressures, and fuel compatibility with the manufacturer, and let the torch’s own manual take precedence over any figure here.
At this output level, both torches are serious oxygen consumers, and the supply is half the system. Size your oxygen to the torch before you buy, not after. If you are unsure how to do that, see how many LPM does my torch need. Whichever you choose, fit the flashback protection your torch and gas supply actually call for and run strong ventilation.
Base, mount, and ergonomics: 360-degree adjustability vs bench or hand
The Black Widow is bench only, but its bench mount is unusually mobile: the head tips front to back through nearly vertical, the assembly rotates a full 360 degrees, and the base rises and falls for a standing artist or for larger pieces. If your work has you moving around the flame, that adjustability is a strong argument on its own.
The Delta Elite is Bench or hand. The standard product is a four-stud bench torch, and GTT sells a separate hand-torch version with its own controls and pricing. So the Delta Elite’s flexibility is in where the torch lives, bench or hand, while the Black Widow’s flexibility is in how the bench-mounted head moves. If you specifically want a hand-torch option in this class, that is a point for GTT; if you want a rotating, height-adjustable bench station, that is a point for Carlisle. For heavy sculptural work generally, see best bench burner for thick glass sculpture.
Worth noting for GTT shoppers: if this output level is more torch than you need, GTT’s Sidewinder is a smaller two-stage sibling with its own selectable center (a standard-mix Bobcat or Triple Mix Lynx), which brings a bit of GTT’s center-choice idea to a lower tier.
Price and who each torch is for
Both prices are reference figures, not fixed quotes. The Delta Elite’s $2,575 is GTT’s list for the standard four-stud bench model, with the hand-torch version priced separately. The Black Widow’s $2,207 is a Carlisle “from” starting price, and center-fire choices and options add cost. Confirm the current number with the maker before buying.
- Choose the Carlisle Black Widow if you want to specify the center-fire character to your work, premix or surface, and want a bench station that rotates 360 degrees and adjusts in height for standing or large work. It rewards owners who value configurability and physical adjustability.
- Choose the GTT Delta Elite if you want one refined, deeply layered Triple Mix flame on the Lynx center, a published oxygen figure to size against, and the option of a bench or a hand version. It rewards owners who would rather master a single engineered flame.
Both are respected top-end torches from established makers. The honest split is not quality but philosophy: the Black Widow gives you levers, the Delta Elite gives you a finished flame.
