    I believe it means the unit is designed to work continuously 12% of the time @ 80 amps and continuously 20% of the time @ 60 amps.

    It relates to the amount of time within a ten minute cycle that one can operate the electrical appliance without risk of overloading or overheating. So 12% would be 1.2 minutes out of every ten, and 20% would be 2.0 minutes, and so on. If it is a welding machine, some of them have overload capacitors built in to shut off the current if the transformer overheats.

    spot welding will not over load the machine.you should be fine.
