    Default 7018 rod.

    Do I have the amp's too high when the rod is only two inches left and it is red red hot in color when I pull away, and I mean the whole of the rod. I open the holder, drop the remains of the rod on the floor and it is bright red.
    My Dynasty does not make the rod red at 70 amps but the CST 280 does. Digital display on Dynasty but just a nob on the CST 280, so not as precise.
    May sound a stupid question but it is very visible.
    Thanks for answer in advance.

    What size rod is this, a 3/32 runs at 85A or maybe a pinch more.

    Shoot, that's how I know my machine is running a good heat. I set it at 90A for 3/32, and it will almost always turn cherry by the time the rod is burnt. Only time it's a problem is if you have to bend your rod, as it will always heat up right at the bend and sometimes falls apart.

    No that is pretty common for 7018 to burn hotter than other rods. You can run 3/32 rod all the way up to about 90 before it would get too hot. In general that rod gets hotter as the rod burns down

    No, it shouldn't turn red hot like this. Something is wrong.

    You can burn the rod as hot as the parent metal allows. Sometimes as high as 115 amps for 3/32. I'm in a unique situation, but do it lots of times. And no, I can just use bigger diameter rods...

    Red is good if you get too the end of the rod it should be glowing orange and your slag should be peeling off behind you

    I agree, that's how to tell when heat is set correctly.
