Patent number: 6318614Abstract: Wire feed rollers made of ceramic material which virtually eliminate wire feed roller wear enabling continuous wire feed to the welding tip without discernable weld wire slippage. Adjacent ceramic wire feed rollers are used in sets where one roller includes a groove on a side surface while the second roller has no grooves. The ceramic wire feed rollers require relatively light clamping (contact) loads to effectively feed the wire to the weld tip enabling decreased wire feed roller drive torque requirements and reduced wear to drive gears and support bearings.Type: GrantFiled: June 1, 2000Date of Patent: November 20, 2001Assignee: Ceramic Engineering Consulting, Inc.Inventor: Gary L.
