L‑Tec PCM‑32i (part 680536) is a single‑phase 220 V plasma cutter with a 29 A output and an OCV max of 210 V, designed for portable metal cutting applications. Common failure points include power supply instability, air pressure regulator or filter blockages, worn torch electrodes, and controller board component failures such as damaged MOSFETs or blown fuses. Begin troubleshooting by verifying the input voltage and current against spec, checking the compressed‑air source for correct flow and pressure, inspecting the torch for electrode wear or debris, and reviewing any fault codes displayed on the console. If those checks are normal, perform a visual inspection of the control board for burnt components or loose connections before proceeding with component replacement.[oss-gpt-20b]
