Industrialgrade welding pen tool set engineered for precision and durability. Aerospacegrade construction provides a robust metal and plastic build that stands up to frequent use while delivering accurate results for welding, cutting, and rust removal tasks. Key benefits Precise temperature control for consistent results: fully automatic intelligent control with internal heating regulates temperature for repeatable performance across small and large jobs. Fast heat up and stable operation: upgraded 80W soldering iron reaches working temperature in 1 to 3 minutes and holds a steady range from 180C to 500C (356F to 932F) for reliable soldering and metal work. Versatile toolkit for many applications: includes a 60W external heating soldering gun plus the upgraded 80W iron for greater flexibility when switching between fine electronics and heavier metal tasks. Easy monitoring and adjustment: resolution digital display provides realtime temperature readout so users can fine tune settings for precision work. Portable and ergonomic design: compact components and userfriendly handles make the set suitable for field service, workshop bench work, and hobby benches. Functions and performance Internal heating technology and power design improve heat dissipation and extend component life for sustained operation. Auto feed solder capability supports continuous soldering where needed, increasing efficiency for repetitive tasks. Compatible with solder wire 0.8 to 1.2 mm in diameter and spool weight 50 to 100 g, simplifying setup for most common soldering jobs.
