XLNT ARC400 IJ GREY 400A Industrial ARC Inverter Welding Machine

The XLNT ARC400 IJ GREY is an industrial ARC inverter welding machine designed for structural welding, heavy fabrication, maintenance and professional workshop applications. It offers adjustable welding output reaching a listed maximum of 400A, allowing the operator to select the required current according to the electrode, metal thickness, joint design and welding application.

The machine operates on a listed 415V ±15% electrical supply at 50/60Hz. The supplied specification image also lists an 18.6A rated input current, 65V no-load voltage, 60% duty cycle, 85% efficiency, 0.93 power factor, Class F insulation and IP21 housing protection.

The live website currently displays a 30–400A output range and positions the machine for structural welding and heavy fabrication. It is listed at ₹25,399 against an MRP of ₹38,999 and is currently marked sold out.

Adjustable Welding Output up to 400A

The supplied image lists an output-current range of 50–400A, while the website lists 30–400A. The maximum listed output is consistently shown as 400A, but the minimum-current specification requires confirmation.

Recommended temporary wording:

Maximum Listed Welding Current: 400A

Output Current Range: Verify whether 30–400A or 50–400A

The correct welding-current setting depends on:

• Electrode diameter
• Electrode type
• Base-metal thickness
• Joint design
• Welding position
• Required penetration
• Material condition
• Electrical-supply stability
• Duty-cycle limitation

Do not claim continuous 400A output unless the manufacturer supplies a current-specific duty-cycle chart.

415V Industrial Electrical Input

The machine requires a listed 415V ±15% electrical supply. The supplied specification image lists a frequency of 50/60Hz and rated input current of 18.6A.

Confirm the following before installation:

• Single-phase or three-phase configuration
• Recommended MCB or MCCB
• Input power-cable size
• Industrial plug and socket rating
• Earthing requirements
• Isolation-switch requirement
• Maximum input current
• Power-cable length

This machine should not be connected to a normal 220V household socket unless the physical rating label specifically confirms 220V compatibility.

Electrical installation should be checked by a qualified electrician.

Rated Input Current of 18.6A

The supplied specification image lists a rated input current of 18.6A.

Confirm whether this represents:

• Rated current at maximum welding output
• Input current per phase
• Current at the listed duty cycle
• Current under a specific test condition

Do not select electrical protection equipment using only this figure without checking the product manual or physical rating plate.

65V No-Load Voltage

The supplied image lists a no-load voltage of 65V.

No-load voltage is present when the machine is powered on but an arc is not being produced. Operators should avoid contact with exposed terminals, electrode holders or conductive welding components while the machine is energised.

Listed 60% Duty Cycle

The website and supplied image both list a 60% duty cycle.

Recommended wording:

Listed Duty Cycle: 60%

The available information does not state:

• The output current used during testing
• The ambient test temperature
• The applicable test standard
• The required cooling period

Do not publish “400A at 60% duty cycle” unless that exact figure is supported by official documentation.

The current website use case “continuous duty welding” should be removed because it may mislead customers when the published duty cycle is 60%.

Listed 85% Efficiency

The XLNT ARC400 IJ GREY has a listed efficiency of 85%. This specification is also displayed on the live website.

Avoid making direct efficiency comparisons with other welding machines unless all models were tested under the same technical standard.

0.93 Power Factor

The supplied specification image lists a power factor of 0.93.

This value is useful for professional buyers and electrical-installation planning and should be included in the technical specification section.

Digital Welding Control Panel

The supplied product image appears to show two digital displays and multiple adjustment controls.

Confirm whether the control panel provides:

• Welding-current adjustment
• Arc-force adjustment
• Hot-start adjustment
• Hot-start duration
• Error-code display
• Thermal-warning display
• Voltage display
• Current display

Until these functions are physically confirmed, use:

Digital Welding Control Panel

Do not add hot start, arc force, anti-stick or VRD as confirmed features based only on the appearance of the controls.

ARC Welding Applications

The ARC400 IJ GREY is listed as an ARC inverter welding machine. Confirm whether the manufacturer also officially classifies it as an MMA or stick welding machine.

After confirmation, suitable product terminology may include:

• ARC welding machine
• MMA welding machine
• Stick welding machine
• Manual electrode welder
• Industrial inverter welding machine

Do not advertise TIG or MIG operation unless those processes are officially supported.

Suitable for Structural Welding

Structural welding is listed as a use case on the live product page.

Actual structural-welding suitability depends on:

• Approved welding procedure
• Compatible electrode
• Material grade
• Joint preparation
• Welder qualification
• Required inspection
• Project-engineer approval

The product page should not replace an approved welding procedure for safety-critical structural work.

Suitable for Heavy Fabrication

Heavy fabrication is another use case currently listed on the website.

Potential applications may include:

• Machinery frames
• Industrial equipment
• Heavy steel assemblies
• Construction components
• Agricultural equipment
• Workshop fabrication
• Maintenance welding
• Structural metalwork

Suitability depends on the electrode, material thickness, duty cycle and verified output performance.

25kg Industrial Construction

The supplied specification image lists a net weight of 25kg and dimensions of 480 √ó 240 √ó 430mm.

The two carrying handles can support controlled movement, but two-person lifting or a suitable welding trolley may be safer depending on the workplace.

Confirm whether the dimensions refer to:

• Machine dimensions
• Carton dimensions
• Shipping dimensions

IP21 Housing Protection

The website and supplied image list IP21 housing protection.

IP21 does not mean the machine is waterproof. Keep it protected from:

• Rain
• Water spray
• Standing water
• Wet workshop floors
• Damp storage
• Excessive grinding dust
• Conductive metal particles

Keep the ventilation openings unobstructed during operation.

Class F Insulation

The supplied image lists Class F insulation.

Include this value in the technical specifications, but do not use it to claim a specific maximum operating temperature without official manufacturer documentation.

Accessories Require Confirmation

The live website lists:

• Welding Machine
• Optional Accessories

This does not explain what the customer receives.

Physically confirm whether the package includes:

• Electrode holder
• Electrode-holder cable
• Earth clamp
• Earth-clamp cable
• Power cable
• Industrial plug
• Remote controller
• Welding mask
• Wire brush
• User manual
• Warranty card

Replace “Optional Accessories” with a clear included-versus-optional accessories list.
