Wow didnt know an actual kemppi forum existed until I did a search just now and found this place and lots of current posts here too!
I got a mls2300 that I just fixed from having no arc.
What it turned out to be was the coolant coolant current line between the torch and the machine (only 1.8meters back from the torch). I found this by putting a multimeter on the leads and realizing their was no connection. Problem for me was I assumed it was all a one piece lead right through from the machine to the torch but its not on these it the coolant only goes into the main current line for cooling and compactness for the last 1.8 meters of the torch lead.
Another thing i found when ordering spare parts to fix this is kemppi dealer here in NZ sent me the wrong part. (actually the newer torch replacement part perhaps for the new flex line of torches im not sure. PN = TKSP014966
Once I got it and I couldnt be fked sending the part back as it was near identical to the proper part other than having a very long hose barb at one end which I cut off then dremelled the end to shape to suit the gas type fitting it uses to connect at the lead end (not the torch end). I think this will work out well because the holes in the ends of this part are actually slightly bigger by about mm or or a bit more so allowing perhaps more water to flow through the system.
So not only is that part cheaper than the original correct part it may be slightly better if you can modify it to suit.
What I noticed is sometimes I was getting seemingly blockages and my water pump would slow down. One cool thing about the mastercool20's is they will shut down when overloaded thus probably saving the electric motor pump.
So if people start noticing their pump is making a slower turning noises than normal you probably need to look at this lead. I left mine like this for over a year before it failed outright and then I realized what the actual problem was. I thought my actual torch head was slowly getting blocked....
So yeah had my mls2300 for probably 8 years or more now very happy with it. Was thinking about "upgrading" to the 235 but TBH the display looks like more of a hinderance than a help to me as most of the chit on that display seems aimed at novice welders. I like to be able to just walk upto the machine and push buttons and not have to jump through endless selection screens to select what I want.... the only advantages I can see to that machine is its new (so hopefully you wouldnt be dealing with this crap above for 10 years) and the double pulse function on DC stainless sounds like a nice feature but probably not game changing.
