Yes, the cheap used battery charger clamps i threw on there to test, doesnīt have much power in their springs, which highly reduces their amount of contactpressure.
It did heat the tube to a glowing red, but made no holes...would though, had i stepped on that pedal just a sec or two more.
Havenīt thought about any type of regulation, as i honestly donīt think that iīll ever need it.
Am quite certain that once ot has been used for a while, one will learn exactly how much it heats, and be ready to lift the foot from the pedal accordingly.
I will however train my "feel" on some scrapped parts initially, as an "OOPS" wouldnīt be desable on anything of value.
