content: My JBC tip (C245944) stopped working after 6 months of sporadic use. The unit showed warning #2 (Open circuit. Check the tool.) and started working again after replacing the tip.This seems like a VERY short lifespan to me. I contacted the company I bought the unit and tips from (Kaisertech in the UK), and they contacted JBC for me. The response was that the tips are considered consumables and don't come with a warranty. Apparently I should learn how to properly look after a tip so my tips may last longer. Let me say, I've been soldering for 20 years, previously used Hakko tips that lasted about 10 years, and always clean the tips with a wet sponge and tin them when I've finished working. I don't think I'm doing anything wrong.What do you guys make of these JBC tips? Was my tip simply faulty (in which case it really should be covered by warranty) or do they all fail after 6 months?

content: General tip (not related to your issue) is to avoid a wet sponge and use brass wool. Less thermal shock, less abrasion, less contamination (if not using deionized water). Also flux is corrosive - minimize contact with the tip.

content: Comparatively short tip surface life has been mentioned a few times before as well as the tip not matching the displayed temp. I don't own a JBC station but from watching videos and looking at their own performance charts it appears that they sacrifice heating accuracy for increased performance. You could check this for yourself and measure the overshoot when heating from cooler temp and if your tips or station are calibrated at idle temp. I've not seen people mention outright failures but it might be related.If your model has a power setting in the config, you can lower it and the station should heat more accurately, reduce overshoot and undoubtedly extend the tip life. But it will mean it reaches set temp slightly slower.The other options for extending tip life as mentioned is reduce thermal shock, have the iron in sleep, setback or off when not using it more frequently and lower the set temp. JBC make some suggestions on their website. Ignore the charts unless you want to believe a JBC can perfectly self regulate in 500ms.https://www.jbctools.com/prolonging-tip-life-menu-5.htmlThe genuine Hakko tips have a good reputation, but aren't comparable in performance due to the reduced station power delivery and cartridge design. If I was to guess Hakko probably uses more plating on their tips as noones ever mentioned them dying fast. But this could be all related to how fast and aggressively you heat the tip (along with the other factors I've mentioned and linked to).

content: Wrote an e-mail to JBC. Explain them it's their heating element inside the cartridge that went belly-up, and that indicates a hidden fabrication defect, it's not because of external care gimmicks. Tell them the exterior coating is in good condition (if it really is), and not pierced.

content: The other cause of failures is dropping your cartridges, probably the fastest way to break the elements or wire connections. Worth a try sending them a message directly though I doubt they will cough up based on others experiences.

content: There was a picture with a C245 cut in half, I can not find it again now. C245 is monocartridge. The heating element, the thermocouple and the tip are making together a single body. Interior was filled, I don't remember any empty spaces that could make internal parts wiggle or shatter at impact.JBC response sounds like a formal retail template response: Consumables not covered by guarantee.I bet JBC will consider the situation if the case is properly explained to them, and if the tip is sent as evidence. Their products are way too expensive to ignore any complains.

content: Quote from: gabinetexSame experience, and same thoughts. I've run dozens of stations IN a daily production environment as well. Very likely a fault or unseen accident or maybe even a FAKE tip? possible?

Perhaps JBC tips are more sensitive to the thermal shock due to thin plating.

content: I have several jbc tips that I use day in, day out and they are original from when I bought my system 4 years ago. There are a few others for special use and they might get used once a month.The only failures I’ve had are from the very fine point tips (0.3mm) being damaged after about 6 months of heavy use. I put that down to being a fine point tip, so those I treat as a consumable

content: Quote from: gabinetex on December 06, 2019, 05:15:20 pmYes this was the first tip I used on this station when I got it new. The station is CD-2BE. It does seem strange that my tip failed in this way. It doesn't look damaged in any way.

content: Quote from: RoGeorge on December 06, 2019, 04:47:13 pmThanks, I'm going to try this. The exterior coating is in good condition and it does seem like a fabrication defect. I'll let you know what they say or if they even reply.

content: Hi,I have failing tip, open circuit. Tried to disasemble by cutting contact end to slide plastic down. Than, i see that cartrige cannot be dissasembled, and try it one more time. Put it back in handle, and tip started workin again !Maybe contact on middle sleeve is loose, this is heater contact. I can't see other possibility.

content: you have to do xray to see that it has internal heating wire broke due to hidden factory defect. but since jbc says its consumables you can only try to get moneyback by court. too much efforts.jbc have very thick heating wire inside, but 1) in original station there is transformer and 2) thick wires dont raise resistance when heated. so some tips have 2ohm res which results in 250-300 watt startup. this is very heavy thermal shock. original stations somehow limits power by using AC power, but its not as much as needed. i have custom built station and once accidentally started tip at 300 watt DC, which resulted in cracking sound and lost contact. actually it was caused by arc in tip holder. after that i limited PWM to 150 watt cold start.also dont forget about plating . jbc has tips with "normal", thin(high thermal conduction) , and heavy duty coating. normal coating is like 0,15mm, which is twice thinner than hakko normal. thin have like 0,1mm coating or less. you should never ever use these tips with acidic flux.so to ensure long life - dont use wet sponge, acidic flux, dont raise temp, high thermal conduction tips work similar to pure copper. and if u use custom built station - limit power usage.

content: Quote from: wickated onTodayat 09:17:33I doubt it, plating thickness will depend on the size and geometry of the tip in question, so that's many different plating thicknesses, hundreds in theory, not just 3 for all of them.For example, a C245-966 (6.6 x 1.8mm chisel) has about 0.5mm thick plating.C245-406 (1.2 x 0.7mm chisel) has about 0.2mm.These happen to be the only 2 tips I know for a fact their plating thickness. For the rest I can guess.A C210-020 (0.1mm conical) for instance, I don't think can have much more than 30µm thick plating.Given the sizes and geometries mentioned, I doubt you can meaningfully increase the plating thickness, let alone double it, without rendering the tips totally useless. You do need a certain amount of copper near the end of the tip, it can't be all iron.

content: Used 2 C245 tips for almost 7 years, maybe 30mins a day (some days all day long, while little or no use in others).The one I used more weared out on the head after 5 years.But never got any heater failure.The fakes from AliExpress did. One lasted 10 minutes.Post pictures of the tip, maybe it gives some hints and shows to be a counterfeit.It wouldn't surprise me that some people start selling these as genuines, the gains would be huge!
