Advanced Heating & Cooling TechnologyThe heated ceramic technology inside the soldering gun can heat the soldering iron quickly and save energy, it is also good for stable temperature, the four ventilation holes on the soldering gun provide better heat dissipation, which can extend its lifespan. Upgraded soldering iron with the latest designthe new on/off switch added on the soldering iron gun makes it more convenient to use, also ensures the safety soldering and energy saving ; the adjustable temperature design 200~450C can satisfy different soldering work conditions. Soldering Iron with Desoldering PumpThe desoldering pump is made of high-pressure vacuum tube and aluminum frame, which can be operated with one hand, can absorb a large amount of solder while the soldering wire is better to absorb a small amount of soldering.
