Where to Buy Esab Caddy Mig C200i IGBT Module 0349312345 DP50L600T111605?

The discussion centers on sourcing and repairing the defective IGBT power module (0349312345 DP50L600T111605) for the Esab Caddy Mig C200i welder. The original module is difficult to find on the market, with official service offering the entire power plate at a high cost (~2,400 PLN). Alternatives include fabricating a replacement module from individual components, with estimated parts cost around 250 PLN. Key damaged components identified include the ZTX 949 transistor in the upper key control circuit and the R235 resistor (1.5k ohm) on the control board. Suggestions include rewiring damaged hybrid elements externally and substituting similar transistors like the ZTX 951. Mouser was recommended as a parts supplier. Users shared images and schematics of homemade replacement modules and discussed protective measures such as interlining and metal mesh to prevent damage from filings. The relay K1 was identified as a 12V relay. Some users requested component lists, capacitor values (C103, C104, C114), and contacts for custom board fabrication. The problem of no feeder wire and no voltage output was linked to possible IGBT module failure. Overall, the community focuses on DIY repair solutions, component substitutions, and sourcing parts due to the scarcity and cost of original modules.
