To help engineers and procurement personnel quickly search and verify, we have meticulously compiled all core part models, names, and specifications for the OTC Daihen T500P Welding Machine. This list has been professionally proofread to correct severe original manual scan errors (such as confusing O with 0, garbled symbols, and mistaking Q for Ω), consolidating identical parts for a clean and accurate display.
