Is Used 95% New Fujikura FSM-90R Ribbon Fusion Splice Mass Welding Splicer with RS03 Thermal Stripper Very Low Arc Count 1041 Excellent Working Condition worth the money?

Absolutely, for the right user. At roughly half the price of a new unit, with verified low usage and a complete accessory kit, it offers tremendous ROI for professionals. The time saved using mass fusion over single-fiber splicing quickly justifies the investment through increased job capacity and lower labor costs.

How does it compare to a new Inno Instrument mass fusion splicer?

The Fujikura FSM-90R is generally considered a more robust, industry-standard platform with potentially better long-term resale value. A new Inno may come with a full warranty and similar specs, but the Fujikura brand carries significant weight for reliability and service network. This used Fujikura offers a way to get that premium brand pedigree at a competitive price point.

What’s the learning curve for beginners?

If you are already familiar with fusion splicing concepts, the learning curve is moderate. The machine guides you through the process. The most challenging part for beginners is mastering the ribbon preparation (stripping and cleaving) with the CT50 and RS-03. With a day or two of practice, most technicians become proficient.

What accessories or additional items do I need?

The package is remarkably complete. You will need to purchase consumables: ribbon fiber heat shrink sleeves, 99% isopropyl alcohol, and lint-free wipes. A spare battery is a highly recommended addition for all-day field work. Otherwise, you can start working immediately.

What warranty and customer support does it offer?

As a used item sold by a third-party, it comes with the seller’s warranty, not Fujikura’s factory warranty. Typically this is 30-90 days for functionality. Fujikura’s global service centers will still service the unit for a fee. Always confirm the specific warranty details with the seller before purchasing.

Where can I buy Used 95% New Fujikura FSM-90R Ribbon Fusion Splice Mass Welding Splicer with RS03 Thermal Stripper Very Low Arc Count 1041 Excellent Working Condition at the best price?
