Flame Length Guide: Match Torch Reach to the Task
Flame length is the working distance a torch gives you - and the first specification to match to the task. ZHENTANZHE torches deliver a flame of up to about 50 cm at high setting, varying roughly ±10 cm with altitude, pressure and temperature. This guide turns that number into a decision: which tasks suit the 32 cm compact body, which need the 60 cm standard, and which really call for the 76 cm long-reach wand.

Two different "lengths" get mixed up in torch conversations: the length of the flame and the length of the tool. They answer different questions. The flame decides how far the heat reaches into the work; the body decides how far your hand sits from it. Choosing a torch means getting both right for the job at hand.
The short answer
Kitchen work happens close, charcoal lighting needs airflow under the coals, and flame weeding wants distance. All three torch bodies produce the same flame specification - what changes is how far your hand sits from it. Match the body to the reach the task demands, then confirm flame behavior with a sample under your real conditions.
The three torch bodies
| Model | Body length | Net weight | Ignition rating |
|---|---|---|---|
| GF-8010 Compact Torch 8010 | 32 cm | 587 g | Electronic, 5,000+ ignitions |
| GF-8012 Standard Torch 8012 | 60 cm | 860 g | Electronic, 5,000+ ignitions |
| GF-8016 Long-Reach Torch 8016 | 76 cm | 550 g | Electronic, 5,000+ ignitions |
Flame up to ~50 cm and up to ~1,300°C, varying about ±10 cm with altitude, pressure and temperature - listed by the factory as common specifications for the platform. Operating range -30°C to 30°C.
The task-to-reach matrix
| Task | Reach demand | 8010 (32 cm) | 8012 (60 cm) | 8016 (76 cm) |
|---|---|---|---|---|
| Culinary searing and finishing | Short, precise, close control | Suited | Suited for volume work | Too long for kitchen work |
| Charcoal and grill lighting | Airflow under the coals, some depth | Suited | Suited | Suited - deep or wide grills |
| Flame weeding | Sustained work at a distance | Limited reach | Workable | Designed for it |
| Livestock and farm tasks | Controlled distance | Limited reach | Suited | Suited |
| Paint stripping and DIY | Close, controlled heat | Small parts | Suited | Less suited |
| Frost and equipment work | Distance from machinery | Limited reach | Suited | Suited |
"Suited" reflects the reach the task demands relative to body length - it is buying guidance, not a lab result. Flame specification is common to all three models.
What "up to ~50 cm" really means
Treat ~50 cm as an envelope, not a promise. The figure varies about ±10 cm with altitude, pressure and temperature, and the knob position sets where inside the envelope you work. A torch that reaches 50 cm on a warm afternoon at sea level will carry a shorter flame in cold weather or at altitude - that is physics, not a defect. It is also why the sample stage matters: run the flame in your market's real conditions before committing a program, and read the short-flame cases in the flame color chart before assuming the tool is at fault.
How to use this guide
Find your task row, read which body lengths carry it comfortably, then check your environment. Expect the shorter end of the flame envelope in cold, at altitude, or with standard butane in near-freezing work - high-altitude blends hold the flame steadier. For flame weeding specifically, pair the 76 cm body with the working practices on the weed-control page. Finally, confirm with a sample order: the factory's figures are the starting point, your site conditions are the verdict. Reach is also a safety margin - the longer the wand, the further hands and knees sit from the flame.
Safety around a working flame
Keep body parts out of the flame path, work with the wind rather than against it, and never leave a lit torch unattended. Every model carries the line's safety design: valve-linked auto shut-off that cuts the gas supply when the flame goes out, plus over-pressure protection and backfire prevention. Professional tool, not a toy: read the manual before use and keep away from children. Fuel canisters are purchased locally according to local regulations - the torch ships without fuel.
The Standard Torch's commercial workload - searing volume, paint stripping, farm and industrial tasks - is profiled on the GF-8012 product page, and the long-reach model's specification on the GF-8016 page.

FAQ
Frequently asked questions
How long is the flame on these torches?
Up to about 50 cm at high flame, varying roughly ±10 cm with altitude, pressure and temperature. The control knob sets the working point inside that envelope.
Does a longer body mean a longer flame?
No. Flame length is a combustion specification shared across the line; body length determines how far your hand sits from the flame. Reach and flame are separate decisions.
Why is the flame shorter outdoors in cold weather?
Cold slows butane vaporization and altitude changes pressure, so the flame sits at the lower end of its roughly ±10 cm envelope. High-altitude blends hold a steadier flame; the operating range is -30°C to 30°C.
Which torch length suits weeding between garden rows?
The 76 cm Long-Reach Torch 8016 - it is the dedicated weed-control model, keeping the flame at a working distance while you walk the rows.
Is flame length adjustable?
Yes, every model adjusts the flame with a control knob, and the electronic ignition is rated for 5,000+ ignitions. Set the flame to the task, not to the maximum.
