The GAS-TEC 300 hotmelt applicator is powered by butane gas and can be recharged using standard cigarette lighter refill canisters.
The GAS-TEC 300 is a professional hot‑melt glue gun powered by butane gas. It is shipped without gas and must be filled with a standard butane refill (Braun, Colibri, Ronson, Rowenta) before first use. Refilling requires the gas switch to be OFF, holding the can vertically above the gun, and stopping when gas spills from the valve; the process takes about 10 seconds.
Operation is started by a piezo‑electric ignition switch; a faint roar indicates gas flow and a glow in the ignition window confirms ignition. The unit reaches its working temperature of 195 °C (385 °F) after roughly four minutes. Safety features include a cut‑out device that stops gas flow if the combustion chamber exceeds 260 °C (500 °F). General use involves squeezing the trigger to extrude adhesive, with precautions to avoid back‑up of molten glue and to keep the tool away from children and open flames.
| Operating temperature | 195 °C / 385 °F |
|---|---|
| Safety cut‑out temperature | 260 °C / 500 °F |
| Maximum ambient temperature | +50 °C (120 °F) |
| Warm‑up time | ≈4 minutes |
| Gas refill time (empty tank) | ≈10 seconds |
| Fuel type | Butane (standard cigarette‑lighter gas) |
Turn the gas switch to OFF, hold the butane refill can above the gun, keep both vertical, and stop when gas spills from the valve; the fill takes about 10 seconds.
A safety cut‑out device stops gas flow when the combustion chamber temperature exceeds 260 °C (500 °F).
The unit needs about four minutes to reach its operating temperature of 195 °C (385 °F).
Back‑up usually clears itself thanks to the G150 PTFE non‑stick inlet tube; in extreme cases let the gun cool and carefully remove the solidified glue.
