Malectrics spot welder help

Just got a malectrics spot welder.
Followed what half ass directions I could find.
Im using 12v car battery version. It’ll turn on. Allow me to adjust settings, But I can’t get it to weld. I tried automatic and manual. When I hold the electrodes down I get this. Doesnt matter if it’s in auto or manual. 15ms or 25ms

I figured it out. This spot welder doesn’t like expensive Optima batteries for some reason. I tried a different car battery and it worked great.

I think it wont weld if it detecs the battery might be too powerful? I know they dont reccomend over 800 CCA cause it might damage the welder

I have an issue with malectrics spot welder, when it’s on Manual mode, it welds/sparks as soon as both probes touch the nickel.
Also, the welds leave holes on the .15 nickel even if I set the timing really low.

Sparks can be a sign of nickel plated steel. It’s also way easier to weld than pure nickel strips. Did you do the scratch and saltwater test on your nickel?

Yes they are real nickel, I tested them.
I am more worried about the fact that it “welds” as soon as the probes touch the metal, no delay, no waiting for the switch.

@Tamatoa it sounds like you have the auto weld option selected. Go through the menu and choose foot pedal

Thanks for your reply, we actually figured it out in the battery club builder thread. I had the welder mounted backwards :sweat_smile::rofl:.

Apparently when it is mounted backwards, the current travels freely without being controlled by the welder.
