| 摘要 |
A welding machine comprises a welding power source (104); a wire feeder (106) coupled to the power source (104); and at least one sensor (105,107,109) coupled to sense one welding condition. Preferably, it also includes a set up circuit (102) coupled to the at least one sensor (105,107,109), the power source, and the wire feeder (106), wherein the set up circuit (102) automatically sets up the welding machine in response to the sensor (105,107,109). The sensor may be a wise sensor, including a diameter sensor and/or a material sensor, a gas sensor or a workpiece thickness sensor. <IMAGE>
