Key Features
- In the Box: WEP 939D+IV 300W heavy duty ESD-safe soldering iron; 3 replacement soldering tips (13D, 6D, 4.5C), detachable soldering gun, heat-resistant soldering iron holder, a roll of lead-free solder wire (2.0mm, 50g)
- Heavy Duty Soldering Iron Station: suitable for heavy-duty soldering applications such as stained glass, wire/cable splicing, audio connector, ham radio builds and industrial manufacturing, NOT suitable for precision soldering and circuit board soldering tasks. It features adjustable temperature from 392°F to 896°F (200℃-480℃), independent power switch, 3 pre-set channels, built-in PID temperature control, LED digital display, °C/°F conversion, sleep mode and automatic stand-by mode
- Fast Heating & Stable Temperature: 300W soldering station heats up 572°F in just 30 seconds; compared with conventional 300W solder iron, it comes with built-in PID temperature control for fast faster temperature compensation especially when working with components that require fast heat dissipation or for long-time soldering; reduce the risk of overheating the components; built-in transformer ensures reliable long-term performance
- Easy tip change: Tired of buying more irons just to get a new tip? Cartridge-type design allows easy tip replacement; reduce replacement cost-no need to buy a whole new soldering iron or the entire soldering station, just insert into tip slot and tighten the ring to secure
- 3 Preset Channels: save 3 frequently used temperature settings in the soldering station; switch between them with one button; no need to readjust temperature every time
- Sleep Mode & Auto Standby: soldering gun enters sleep mode after 5/10/30 minutes (adjustable) of inactivity; helps reduce oxidation and unnecessary wear of the heating element; if not reactivated within set time, automatically cuts off power to heating element and enters standby mode; extends heating element lifespan
