a magnet will stick to 400 series stainless but not to 300 series (and I believe a lot of stainless stoves were made from 400 series)

someone with lots of experience can make a pretty good judgment by the sparks that come off a grinding wheel

Yep, the local welding shop in town will first grind something to tell if they can weld it, if not sure then they drop it on the concrete to listen to how it rings. On ductile they’ll take a torch and see how the sparks fly and how clean the cut is.

From fifty years of experience the owner of that shop will tell yah some of the poorest ductile they’ve ever seen is JD green, no point in wasting your time as by time you tack the other side the first side will have already popped.

I ask this question because anyone that has a heatmor before 1999 its got a mild steel base . So what happens
base rusts and causes base  tank gasket failure and you will be leaking air and you get a crack in your tank .
and no its not the 409 stainless steels fault its base gasket leaking air making hot and cold spots and stainless will crack and slowly weep water out . So If you do have one and you think ooo its fine . just take tin off sides look behind insulation .
look at the seams between tank and base you see rust . Might want to replace that gasket . Mine looked ok only bit of rust and took tank off and ya scary ridge where gasket is all rusted out inside . Where the most rust was is where tank leaked .
look at picture :) front right corner all rust orange spot is where tank has pin hole . look how close gasket and rust ridge is yep thats where pin hole is . These are my findings . goal is to let others with old heatmors know hey if I replace that gasket . It will give alot longer life . and $7000 for a new one kinda cuts in to the piggy bank .:) aka project long life heatmor  . After 1999 they had a stainless steel base . This leaves 6 year window for the above problem . 1994 were the first year of stainless tanks . 1999 was first year of stainless bases .  :bag:

Picture below is 1994 base installed in 1996:)

second picture is after I took sand out and cleaned off gasket surface .  :bag:

Heat,

Just and FYI....my high limit controller arced out lastnight on my new 400....i went to load before bed and i had no power to the stove....i went into the barn and the breaker was flipped. SO i went back out and started peaking around...the water temp was at 178 and the stove was fine (no evidence of water on the roof, sides or ground from a boiler over). I opened the back panel and i could smell something had been torched....sure enough that new high limit gauge was black on one side and you could see a nice size arc flash mark.....so for now i had to just disconnect it...gonna call today and im hoping they will just send me a new one right away. Only problem is you have to drain the tank down past that gauge to put a new one on.

Just figured i would share. I dont know why it happened. The unit has been running pretty flawless for the past 3 weeks.

So was it that new style high limit where its just look like it screws in . I will take a picture of mine and post it tonight. Sorry to hear the troubles. Seems any thing they change there can be problems. Keep me posted what they say . see if we're better off putting old style back in atless we could change it with out draining it down .

I'm going to put old style back on so I don't have to drain it down to change it . because don't want to be out there at subzero fixing high limit switch. 😀 will look in to old style one. 😀
