Abstract
Apparatus for directing and feeding wire (W) such as for a welder includes first and second, generally planar, guide plates (108) which are slid in a direction parallel to the movement path of the wire (W) into a slit (74) of a mount (68) and a slot (64) of an adapter element (44). A driven roll (20) penetrates an opening (112) in the first guide plate (108). A pressure roll (82) is pivotably mounted to mount (68) between a drive position where it penetrates an opening (112) in the second guide plate (108) and sandwiches wire (W) against the driven roll (20) and a disengaged position. The pressure roll (82) is removably held in the drive position by abutment of a washer (104) with the bracket (84) to which pressure roll (82) is rotatably mounted. The washer (104) is slideable upon a shaft (98) and biased toward the bracket (84) by a spring (106), with the shaft (98) being pivotably mounted to a connecting block (24) between a latched and unlatched position. The adapter element (44) is slideably received in the connector block (24).
