<p>A low voltage, low inductance power supply (170) for supplying a current through a filler wire (140) in order to resistance-heat at least an extended portion of the filler wire (140). The power supply (170) is configured to have an output inductance in a range of 40 to 70 micro henries, a saturation current in a range of 20 to 50 amps, and an open circuit voltage that is less than or equal to 13 volts.</p> |
