    Sorry. I have communicated poorly. My R value is 2.37mR. The manual suggests that I am outside the normal range of 2.5 - 3.0. I have not been getting varying test results. Is it okay that my R value is lower than the manual's range?

    Well. I may have a bad case of the dumb =/. Not sure why I struggled with that so much. Open: Offs = 63 Std = 3.6 Short: R = 2.37mR (typically between 2.5 and 3.0. Any problem with my value?) Std = 30.0 I = 1379A T = 19.6C Battery is a mildly used lead-acid starter battery rated 750...

    Timeout n=000001 E=-23.2J t200.00m I= 1344A R=-0.02m T= 29.4C On a lark I made a couple welds on a dead cell and am getting pretty excited about using this thing in earnest. First pack will be for my 6 year old daughter's Oset trials bike. The stock lead acid batteries weigh more than she does!

    Okay held the knob for the "open" part of the test and got the following values: Offs: 62 Std: 5.6 And: Ok Still don't know why my resistance value was off from spec at -0.02 milli Ohmes, but judging by the lack of concern here, I think I will forge ahead. Sorry for wasting your time with...

    You can also try to run the calibration with the pedal disconnected, by using the dial knob to step through the process: This is the only way I have operated the kweld unit. I have not connected the foot pedal. 4) push and hold button -> OPEN test executes and results are shown on the screen...

    I am using the kweld wires and probes found on the kweld website: https://www.keenlab.de/index.php/product/kweld-cable-electrode-holders/ It was represented to me by the boss that by I am generating much more heat in the calibration process than I will when performing actual welds. Makes...

    kWeld - "Next level" DIY battery spot welder

    I have read and reread the operation manual --particularly the calibration section as it is pretty much step one. The manual says I should see an "Offs" value between 50 and 100, typically. When I run the calibration I get no Offs value. After I press the knob, the "Open" prompt goes to...

    I went ahead and did the calibration again so that I could get proper numbers for you. Post calibration info: Timeout n=000004 E=-23.4J t200.00m I= 1340A R=-0.02m T= 29.4C I have never tried more than a half a dozen calibrations in a go, but those flexible 8ga wires and pens sure do warm up...

    If I am posting in the wrong forum, kindly point me in the right direction. I recently received and assembled a kweld unit. I have a used 750 CCA lead acid starter battery that I connected to the kweld via automotive grade, 4ga wire and typical lead battery clamps. My 4ga to kweld input wire...
