Panasonic YD-400AT3DJT DC Inverter – Welding Machine Spare Parts & Accessories

Description

The Panasonic YD-400AT3DJT DC Inverter is an IGBT-controlled welding power source designed for DC TIG and manual metal arc welding applications. Identified by the model number YD-400AT3DJT, this machine is intended for suitable welding, fabrication, repair and maintenance work. Its inverter-based power control and documented welding-current range make it important to check the machine’s operating requirements before selecting it for a particular application. This listing is organised under Welding Machine Spare Parts & Accessories.

The complete product title, Panasonic YD-400AT3DJT DC Inverter – Welding Machine Spare Parts & Accessories, identifies the equipment and its relevant catalogue category. Keeping the full model number in the product title, description and image information helps distinguish this machine from other welding power sources. Before publishing the listing, compare the actual unit’s nameplate with its documentation to confirm that the model and specifications match.

The YD-400AT3DJT uses IGBT inverter technology to control electrical power conversion. The product documentation identifies it as a DC TIG/MMA welding power source. DC TIG welding uses a non-consumable tungsten electrode and requires compatible torch equipment and shielding gas. MMA welding, also known as stick welding, uses a suitable coated electrode. These processes require different accessories and operating setups, so users should follow the manufacturer’s instructions when selecting the appropriate process.

The documented welding-current range is 20–410 A, with a rated welding current of 400 A. The published rated duty cycle is 60%. These values describe the documented model, but the actual unit’s nameplate and manual should be checked before relying on them for installation or operation. The rated current should not be interpreted as a guarantee of continuous operation at 400 A under all conditions.

Published technical documentation lists a three-phase input supply rated at 415 V, with an allowable voltage fluctuation of ±20%, and a frequency of 50/60 Hz. The listed maximum input capacity at the specified duty cycle is 17.6 kVA and 16.7 kW. These electrical requirements are important when determining whether the available supply is suitable. Installation should be carried out in accordance with the manufacturer’s instructions and applicable electrical safety requirements.

The documented open-circuit voltage is 71 V. The rated output voltage is listed as 36 V for stick welding and 26 V for TIG welding. These technical values should be checked against the documentation for the exact machine version before being used in a product specification table. Electrical connections, protective earthing, cable selection and circuit protection must be suitable for the equipment’s documented requirements.

The machine’s documented TIG functions include gas pre-flow and post-flow controls and current slope controls. The available documentation identifies a fixed gas pre-flow, fixed gas post-flow and fixed current up-slope control, with a listed down-slope adjustment range of 0.5–2.3 seconds. MMA-related documentation lists adjustable arc-force current up to 220 A and hot-start current up to 150 A. Verify these functions on the actual machine before advertising them as available on the supplied unit.

The published specifications also identify forced-air cooling, an IP23 protection classification and Class H insulation. The documented dimensions are approximately 550 × 330 × 600 mm, with a listed net weight of approximately 45 kg. These details can help with equipment identification and installation planning, but measurements and specifications should be confirmed against the actual unit before publication or shipping arrangements.

Compatible Welding Machine Spare Parts & Accessories are important for connecting, operating and maintaining the equipment. Depending on the required welding process, relevant accessory types may include welding cables, electrode holders, work clamps, TIG torches, gas hoses and compatible connectors. These are examples of possible accessory categories, not a confirmation that every item is included with the machine. Check the supplied package and connection requirements before listing accessories as included.

The YD-400AT3DJT may be suitable for compatible fabrication, repair and maintenance applications within its documented operating limits. The appropriate process depends on the material, joint design, electrode or tungsten selection, shielding-gas setup and welding procedure. Users should consult the manual to determine whether the machine meets the requirements of their intended work.

Before use, inspect the machine’s external enclosure, power cable, welding leads and connectors for visible damage. Ensure that the installation provides the electrical supply and ventilation required by the manufacturer. Keep ventilation openings clear and protect the equipment from environmental conditions prohibited by the manual. Disconnect the power supply before performing permitted external cleaning or inspection. Internal electrical servicing should be carried out by a qualified technician.

Welding operations require appropriate safety precautions. Operators should use a suitable welding helmet, eye protection, gloves, protective clothing and footwear. Adequate ventilation is essential, and combustible materials should be kept away from sparks and hot workpieces. Protect nearby people from arc radiation and follow the manufacturer’s operating instructions and applicable workplace safety procedures.
