I've been running a Xc1000 water cooler in regular production for about 9 weeks. All good and smooth, but then a hose burst suddenly last week, at which point I started to realise there were some small blockages, deposits and one inlet not flowing at all (completely blocked).
Only had a recommended coolant in it and distilled water.
The stuff blocking it is a chalky, blue stuff. The coolant is blue. Some quite hard, some powdery, some that's wet is more of a paste.
Tried manually probing some of it out, no great luck, still blocked.
Tried running a general cleaner through for a short period, no luck.
Tried different products to try and break down the chalky stuff, on a small test piece, no luck. Vinegar doesn't do anything. Was losing hope then I tried some household descaler I had about, and strangely, the descaler did dissolve small test pieces over many hours. A lactic acid based one.
How on earth? What even is this? Regular limescale would dissolve in vinegar but this does not.
Abyway, got some strong descaler running through the unit now and it's still blocked. Going to leave it overnight. It's definitely removed some stuff as the water went very blue again, so has picked up some 'stuff'.
The cooler is connected to my induction heater, not a welder, but no one I know who uses an induction has had such issues, hence why asking here. I figure more water cooler / chiller users amongst welding folk may have experienced something similar.
Anyone ever experienced anything like this?
As a side note, the parweld coolant I used, they did change their recipe recently and were explicit with not mixing. Dunno if that's normal or suspicious to change a recipe... Or if it's a signal there was some issue with the batch I had.
Apologies if this is not in the right section, wasn't sure where else would be most appropriate?
