KL-558 Flux Paste and Desoldering Kit

The KL-558 kit supplies a three-piece no-clean rosin flux paste set and a two-piece desoldering wick braid for electronics repair. It is built for technicians and hobbyists who need reliable oxide removal and solder absorption during component rework. The flux paste uses a plunger design for controlled dispensing, while the wick uses high-purity oxygen-free copper for fast thermal transfer. This combination suits bench work on PCBs, home appliances and mobile devices.

Thermals, Noise and Power Draw

The flux paste produces low smoke and a non-irritating odour during heating, keeping the work environment comfortable. Its rosin formulation removes oxide layers quickly, reducing the time a soldering iron must stay on a joint. The desoldering wick absorbs excess solder efficiently through high thermal conductivity, limiting prolonged heat exposure to sensitive parts. No external power or cooling is required for either consumable.

Plunger Dispensing and Copper Braid

The plunger mechanism on each flux syringe delivers a smooth, measured flow that cuts material waste and prevents flooding of fine-pitch pads. The included desoldering braids are pre-fluxed and leave no residue, so boards do not need extra cleaning after rework. Both items are RoHS compliant and lead-free, meeting standards for professional assembly and repair. The five-piece pack keeps consumables on hand for repeated jobs.

Questions about this item

How do I apply the KL-558 flux paste without wasting material?

Depress the plunger gently to dispense a small bead directly onto the joint area; the mechanism meters flow so excess paste is not forced out.

Will the copper braid in the KL-558 kit degrade or need replacement after repeated desoldering?

Each length of oxygen-free copper wick is single-use; once saturated with solder it cannot absorb more and must be discarded.

What stops the KL-558 flux from cleaning effectively during a long rework session?

Heavy oxide buildup or severely contaminated pads can overwhelm the rosin activity, leaving joints that wet poorly despite fresh flux.
