Dressing Electrodes vs. New Tips Worn electrode tips produce either poor welds or no welds at all, limiting both quality and productivity. Two possible solutions to worn tips are to (1) replace them with new, or (2) recondition existing tips on either a lathe, drill press, or with a portable ARO Electrode Dresser. Replacing tips is a costly and time consuming alternative. Reconditioning tips on standard machine shop equipment, although providing uniformly dressed electrodes, cuts valuable production time. Reconditioning worn tips with an ARO Electrode Dresser, however, is a convenient, economical solution that minimizes downtime. Dressing Electrodes with ARO's Portable Electrode Dresser Reconditioning with an ARO pneumatic Electrode Dresser is a quick, easy, and accurate method of dressing worn electrodes. Downtime is virtually eliminated because each electrode is automatically dressed in seconds with precision, without removing the tip from the machine. Once dressed, the electrode has a perfectly shaped tip for producing uniform, quality welds. Furthermore, a properly shaped electrode top reduces energy consumption during the welding process and greatly extends electrode life. ARO Portable Electrode Dressers To reduce production downtime, increase electrode tip life, reduce energy consumption, and maintain quality welds, recondition your worn electrode tips with an ARO Portable Electrode Dresser.
