heat gun
B2Technical / DIY / Professional trade
Definition
Meaning
A handheld electrical tool that emits a stream of very hot air, used for tasks like stripping paint, thawing pipes, or shrinking plastic.
While primarily a tool, the term can be used metaphorically to describe any intense, direct source of heat or pressure. In digital contexts (e.g., 3D printing), it can refer to software-controlled hot-air devices.
Linguistics
Semantic Notes
A compound noun where 'heat' specifies the type of 'gun' (a device that projects something). Not a weapon. Implies controlled, directed application of heat, unlike a general heater.

Memory Aids
Mnemonic
Imagine a HAIR DRYER's much stronger, more focused cousin. It's a GUN that shoots HEAT instead of bullets.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate as "тепловой пистолет" in technical contexts; "технический фен" or "строительный фен" is standard.
- Avoid confusion with "тепловизор" (thermal imaging camera).
- Not a "пушка" (cannon); it's handheld.
Common Mistakes
- Using 'heat gun' as a verb (e.g., 'I will heat gun it'). Correct: 'I will use a heat gun on it.'
- Confusing it with a 'blow torch' which uses an open flame.
- Misspelling as 'heatgun' (acceptable in some technical specs, but standard is two words).

FAQ
Frequently Asked Questions
No. While both blow hot air, a heat gun operates at much higher temperatures (often 100-600°C vs. 60°C max for a hair dryer) and lacks a 'cool' setting, making it unsuitable for hair.
Yes, extremely easily. It is a primary fire hazard if misused. It should never be left unattended while on and must be kept away from flammable materials.
Heat-resistant gloves and safety glasses are essential to protect against burns and debris. Use in a well-ventilated area if burning off fumes.
In professional settings, it's often called a 'hot-air gun' or 'hot-air tool'. In electronics, it may be part of a 'rework station' or 'desoldering station'.
