Patent ID: 8779321

Claim:
A method of welding a circuit conductor and one of a plurality of terminals of only one electronic component of a control apparatus by melting and joining by a welding arc from a first electrode of a micromini TIG welder, the method comprising: setting at least two of the plurality of the terminals of the only one electronic component including the one of the plurality of the terminals to be welded, and another one of the plurality of the terminals of the only one electronic component which is influenced by a flying of the welding arc, to an identical potential by sandwiching the at least two of the plurality of the terminals of the only one electronic component, by an earth clamp jig serving as a second electrode; and arc-welding the one of the plurality of the terminals of the only one electronic component to be welded and the circuit conductor to be welded while the one of the plurality of the terminals of the only one electronic component to be welded and the circuit conductor to be welded are grounded.
