Key benefits Restores nozzle regenerative performance at the operating temperature to improve solder flow and tip efficiency. Removes and helps prevent black oxide buildup on soldering iron tip surfaces, reducing tip darkening and maintenance effort. Tin plating on the welding nozzle enhances tin coverage for reliable retinning and longer tip life. Simple fourstep process designed for quick, repeatable maintenance without special tools. Designed for standard soldering irons with nozzle temperatures in the 300360 C range. How it works (usage steps) Step 1: When the nozzle temperature is 300360 C, perform the regenerative action. Step 2: Apply the regenerative ointment to the welding nozzle and wait a few seconds. Step 3: Tin the welding nozzle by plating tin on it. If the regenerative effect is not obvious, repeat steps 23. Step 4: Wipe off the black oxide from the surfaces of the soldering iron tip to prevent blackening and maintain clean, smooth soldering performance. Applications and practical scenarios Electronics and rework: recondition oxidized or degraded soldering tips to restore solder flow and precision. PCB prototyping and assembly: maintain clean, welltinned tips for consistent joint quality during frequent soldering cycles. DIY electronics and metalworking: extend tip life and reduce tip cleaning frequency with a straightforward maintenance routine. Specifications and notes Temperature guidance: effective regenerative action at nozzle temperatures between 300 C and 360 C. Components referenced: regenerative ointment and tin plating on the welding nozzle are part of the process. Compatibility: intended for standard soldering irons that operate within the specified temperature range. Size and model specifics: not specified; use with compatible soldering irons that support the stated temperature range.
