Hi All!
Yeah, LT means Low Temp!
Easy when you know!
What this means is that these electrodes are suitable for use on stuff that runs really cold, like refrigeration plants etc.
BTW, Technic, whilst I agree with you on the running of 7018 over 7016 electrodes, have you ever tried this on a hobbyists type machine running off mains electric? And I have used some dodgy 7018's in my time!LOL
Regards
Ta for that.
Still a bit of a mystery, but they came from a railway stores 12 years ago.
There was pipework going on at the time, but nothing involving low temperatures. Maybe they were bought in error and just dumped in the corner.
