To help engineers and procurement personnel quickly search and purchase, we have meticulously compiled the parts details for the three major series of plasma cutting torches matched with the OTC Daihen D12000 Plasma Cutting Machine. The original torches are mainly divided into three types: CTW (Short Handle), CTZW (Long Handle), and CTPW (Straight Handle).
To solve the pain point of the original manual where the tables were too complex and merged, making it impossible to match prices using Excel formulas, we have completely flattened and separated the parts for all three series. All accessories are presented with independent order numbers, and scanning typos (e.g., correcting MX35 bolt to M4×35) have been professionally corrected.
