Weller W100P3 100 W Soldering Iron

Soldering iron for heavy joints

The Weller W100P3 is a 100 W soldering iron that reaches its maximum temperature in 110 seconds. It operates on a 120 V supply with a three-prong plug and delivers a tip temperature range of 600 to 800 degrees Fahrenheit. A screwdriver tip from the CT6 series is included.

Suited for thick wire and chassis work

The high power and wide temperature window make it appropriate for heavy-gauge cable, terminal lugs and sheet-metal fabrication where rapid heat recovery matters. Users who need fine-pitch electronics work or temperature-controlled precision should consider a lower-power or adjustable station instead.

Deciding specification: 100 W power rating

The 100 W rating determines whether the iron can sustain heat on large copper masses without excessive temperature drop. If the application involves only small connectors or temperature-sensitive components, a lower-wattage tool will provide better control and reduce the risk of overheating.
