<br>Spot welding is reliant on the ability to conduct high voltages at precise levels with the correct application of pressure and time. This kind of high precision work requires well-maintained tools. The tip sharpener helps you keep your weld caps clear of rust and residue that build up over time from exposure and repeated use.</br> <br>Designed specifically for the i5 A-CAPS. (Please note: If you are looking for the Tip Dresser for the B CAPS, see part number 186-PLT-51A)</br><br/><br/>
