Hobart 203655D Circuit Board

The Hobart 203655D is a field‑current controller circuit board used in Miller‑Electric welding systems (e.g., the 10000 Champion). Common failures include fried varistors on the input line and damaged LT1172IN8 voltage regulator chips after power surges or overheating. Initial diagnostics should verify that the main supply rails are within spec, visually inspect all surface‑mount components for burn marks or cracked packages, and read any stored fault codes from the welder’s control panel to pinpoint a specific component failure.[oss-gpt-20b]
