Summary

The Draper Micro Butane Soldering Iron (Stock No. 78774, Part No. GT8) is a portable, gas-powered soldering tool designed for various soldering tasks. It operates on butane gas and offers a temperature range of 200-400°C, making it suitable for a variety of applications requiring controlled heat.

Function Description:

The primary function of this device is to provide a portable heat source for soldering. It uses butane gas to generate a flame, which then heats a soldering tip. This allows for precise application of heat to workpieces, melting solder to create electrical or mechanical connections. The tool is designed for ease of use and portability, making it suitable for both professional and hobbyist use where access to electrical power might be limited. The control lever allows for adjustment of the flame size and temperature, providing flexibility for different soldering requirements. It can also be used for other heat-related tasks, such as heat shrinking or light brazing, depending on the tip used and the temperature achieved.

Important Technical Specifications:

Stock No.: 78774
Part No.: GT8
Fuel type: Butane
Approx. temperature: 200-400°C
Operating time (one gas filling): Approximately 20 minutes at mid-setting
Dimensions: W 147 × H 35 × Ø 20mm
Weight (80% gas fill): 54g

Usage Features:

Refuelling: The soldering iron is refuelled by pushing a butane can nozzle firmly into the filling valve. Filling is automatic and takes only a few seconds. A window beneath the control lever allows for viewing the fuel level. It is crucial to ensure the control lever is in the lowest (OFF) position before refuelling and to allow a few minutes for the gas to stabilise after filling. Refuelling should always be done outside, and smoking is strictly prohibited during this process.
Ignition: To ignite, the control lever is moved to the ON position to start the fuel supply, and the ignition button is depressed repeatedly until the flame is lit. Users are warned to keep hands and face away from the barrel during ignition.
Temperature Control: The control lever allows for adjustment of the flame size and temperature, providing control over the heat output.
Operation: After ignition, the tool requires approximately 30 seconds for the flame to reach the desired temperature before directing the soldering tip towards the workpiece. Solder is then applied to the point of contact as required, with a reminder not to apply excessive solder.
Safety during Use: The metal parts of the soldering iron become very hot during use, and users are warned not to touch the barrel, soldering tip, or workpiece until they have cooled thoroughly. It is essential to wear appropriate eye and face protection and protective gloves. The product should not be left running unattended, exposed to temperatures above 49°C (120°F), or prolonged sunlight.
Shut-off: To switch off, the control lever is moved fully to the OFF position. The soldering iron must be allowed to cool thoroughly. The clear lid can be used as a stand while cooling.
Orientation: The manual advises against using the product in sideways or inverted orientations as this may interrupt the flow of fuel to the flame.
Reignition Safety: A critical safety warning highlights that if the fuel supply is re-engaged after use, residual heat can cause reignition without operating the ignition button. Therefore, users must always ensure the control lever remains in the OFF position after use and follow the normal ignition procedure once the tool has cooled.
Environment: The device should only be used in well-ventilated environments and not where paint fumes, solvents, or other flammable materials are present. It is not insulated against electricity and should never be used on workpieces connected to electrical power.

Maintenance Features:

Cleaning: The barrel should be kept clean and dry, using only a dry cloth. The soldering tip should be cleaned using a wet sponge while it is hot. Users are warned not to touch any part of the head assembly while the soldering tip is hot. Solvents or aggressive chemicals should not be used for cleaning as they may damage plastic or insulated parts.
Air Vents: The air vents of the barrel must be kept free from dust and obstructions.
Storage: The product should be stored in a clean, cool, and dry location, out of direct sunlight and out of reach of children. Before storing, ensure the flame is fully extinguished, the control lever is in its lowest position, and the product has completely cooled.
Leak Detection: Users are advised to check the soldering iron for damaged, clogged, or corroded parts and leaks before every use. If a gas leak is suspected, the product should be moved to an external environment immediately. Leaks can be tested by dabbing soapy water solution on joints and connections; a steady feed of soapy bubbles indicates a breach point.
Disposal: At the end of its working life, the product should be disposed of responsibly and in line with local regulations, recycling where possible. The fuel must be exhausted before disposal, and butane should be disposed of separately and responsibly.
General: The manual explicitly states, "DO NOT attempt to disassemble or modify this tool in any way." If the product is damaged or leaking, contact Draper Tools for repair and replacement options.
