CPVE400 Welder Parts List | Genuine Spare Parts

I. After-Sales Expert Tips: CPVE400 Core Parts Procurement Guide

When ordering the parts in the table below, please be sure to pay attention to the “collateral damage” rules among components:

• IGBT Module (TR1, TR2) Blowout: If you find the 100-2134 (IGBT module) broken down or blown out, do NOT just buy the IGBT! You must simultaneously test or replace the inverter drive board P30066S (PCB3). A module blowout usually breaks down the drive circuit instantly. If the drive board is not replaced, the newly installed IGBT will explode again the moment power is applied.
• Uniqueness of the Main Control Board P30110P: The heart of the CPVE400 is PCB1 (P30110P). There are many similar-looking obsolete OTC boards on the market. Please make sure to identify the original P30110P00 batch number. Do not mix them up, otherwise, it may cause the wire feeder to lose control or result in no shielding gas output.
• Importance of the Cooling Fan (FM): The aging of the 200FZY3-S axial fan will cause the equipment to frequently report the E300 overheating fault. It is recommended to replace the fan as soon as it makes abnormal noises to prevent accumulated heat from aging expensive power components.
