Key benefits Portable, refillable gas soldering pen that delivers quick, controlled heat for small repairs and precise work. Saves time: fast refills (about 10 seconds) and immediate ignition so you can to tasks quickly. Versatile: designed for electronics and chipboard work, light welding and jewelry repairs. Lowmaintenance, easy to refill and service; uses a widely available 8 ml fuel capacity. Features and performance Refilling: guide the fuel tank into the air inlet and press down to fill. Filling takes about 10 seconds. After refilling, wait a few minutes for pressure and fuel to stabilize before use. Ignition and heating: attach or the soldering tip as needed. Push the ONposition button and you will hear a hiss; then press the electronic ignition button to light. Allow the flame to burn for approximately 3 minutes. When the flame is extinguished, the soldering iron head will continue to remain hot for soldering. Refillable and maintainable: designed for repeated use with standard refill procedures and routine tip replacement. What it solves Provides a compact, heatready tool for field repairs and bench work where fullsize soldering stations or torches are inconvenient. Reduces downtime with fast refills and immediate heating: ideal when you need precision heat without lengthy warmup times. Refillable 8 ml capacity decreases consumable waste and keeps the tool ready for multiple jobs before refilling. Compatibility and practical details Intended for work on electronics, chipboards, light welding tasks and jewelry soldering. Tip replacement and basic maintenance are straightforward to extend tool life. Uses common 8 ml fuel cartridges for easy refills. Practical use scenarios 1) Electronics : desolder and resolder small components on PCBs and chipboards, using the heated iron head after the flame phase for precise soldering. 2) Jewelry : perform small solder joints and local heating tasks where controlled, portable heat is required. 3) Light metalwork and field welding: perform minor repairs or heating tasks on small metal parts where a compact, refillable heat source is needed. Notes for reliable operation After filling, wait a few minutes for the unit to stabilize before igniting. If you hear a persistent hissing sound after filling, press the pen tip gently into the air outlet to check or relieve residual pressure before igniting. tips as needed; follow the attachment procedure before turning the unit on.
