MikeFM: A regular desktop power supply can be had for around the same price as a genuine Apple power adapter and can supply enough current to weld with! There are regular articles in the electronic magazines on what value resistors you need to put across some of the pins to ensure startup and regulation is reliable. As a bonus you have 12volts and 3.3volts for charging other items. Excellent value.
