XLNT MIG 400H 400A Industrial MIG Welding Machine

The XLNT MIG 400H is a high-output industrial MIG welding machine designed for heavy fabrication, structural welding and professional metalwork. It provides a listed adjustable output-current range of 80-400A, allowing the operator to select an appropriate welding current according to the wire, base-metal thickness, joint design and welding application.

The machine operates on a listed 415V ±15% three-phase electrical supply and supports 50/60Hz frequency. It has a listed 60% duty cycle, 85% efficiency, 0.93 power factor, IP21 ingress protection and Class F insulation.

The live product page positions the MIG 400H for industrial welders, fabricators and construction sites. It specifically lists heavy fabrication, structural welding and industrial MIG welding as intended applications.

80-400A Adjustable MIG Welding Output

The XLNT MIG 400H provides a listed output-current range of 80-400A.

The correct welding-current setting depends on:

• Welding-wire diameter
• Welding-wire type
• Base-metal material
• Base-metal thickness
• Shielding gas
• Wire-feed speed
• Welding position
• Joint design
• Travel speed
• Electrical-supply stability

The supported wire diameters and wire types are not currently published. These should be confirmed before adding a wire-selection chart.

400A Maximum Listed Output

The machine is marketed as a 400A MIG welder, and both the supplied specification image and live page show an output range up to 400A.

Recommended technical wording:

Maximum Listed Welding Current: 400A

Do not claim continuous 400A output unless the manufacturer provides a duty-cycle chart showing the operating duration at 400A.

415V Three-Phase Electrical Input

The XLNT MIG 400H requires a listed 415V ±15% three-phase electrical supply. The supplied specification image lists a rated input current of 22.8A and a frequency of 50/60Hz.

Before installation, a qualified electrician should confirm:

• Three-phase electrical availability
• Phase configuration
• Input-cable size
• Earthing requirements
• Recommended MCB or MCCB
• Industrial plug and socket rating
• Isolation-switch requirement
• Extension-cable suitability

This machine should not be connected to a normal 220V single-phase household socket. The live page specifically identifies the input as 415V ±15% three-phase. 

Rated Input Current of 22.8A

The supplied specification image lists:

Rated Input Current: 22.8A

Confirm whether this value applies at maximum output or under another specified operating condition before recommending circuit-protection equipment.

60V No-Load Voltage

The MIG 400H has a listed no-load voltage of 60V.

No-load voltage is present when the machine is switched on but welding is not taking place. Avoid contact with exposed welding terminals and conductive parts while the machine is energised.

Listed 60% Duty Cycle

The XLNT MIG 400H has a listed duty cycle of 60%. This figure also appears on the current product page.

Duty cycle indicates how long the welding machine can operate during a defined testing period before requiring cooling.

The available information does not state:

• The welding current used during testing
• The ambient test temperature
• The applicable technical standard
• The required cooling duration

Use:

Listed Duty Cycle: 60%

Do not claim ‚400A at 60% duty cycle‚ unless official documentation confirms it.

Listed 85% Efficiency

The MIG welding machine has a listed efficiency of 85%. The live page also highlights 85% energy efficiency.

The applicable testing standard is not published, so avoid direct efficiency comparisons with other welding machines unless all products were tested under equivalent conditions.

0.93 Power Factor

The supplied specification image lists a power factor of 0.93.

This is useful electrical information for industrial customers and electrical-installation planning. It should be retained in the technical specification section.

Digital Welding Control

The live page promotes digital arc control, and the product image appears to show a front control panel with digital display and adjustment controls.

Confirm exactly what the display shows:

• Selected welding current
• Welding voltage
• Wire-feed speed
• Actual operating current
• Error codes
• Thermal warning
• Program or mode settings

Until verified, use:

Digital Welding Control Panel

Avoid claiming real-time current or voltage accuracy without manufacturer confirmation.

Separate Wire-Feeder Configuration

The supplied image appears to show a separate wire-feeder unit connected to the main welding power source.

An external wire feeder can provide practical flexibility when working around large fabrication structures, but the website does not clearly name the feeder under package contents.

Before publication, confirm:

• Whether the wire feeder is included
• Wire-feeder model number
• Number of feed rollers
• Supported wire-spool weight
• Supported wire diameters
• Wire-feed speed range
• Interconnecting cable length
• Feeder input voltage
• Torch connection type
• Euro connector availability

Do not advertise “external wire feeder included” until the actual package is checked.

MIG Welding Torch Included

The current website lists a welding torch under “In the Box.”

Confirm:

• Torch model
• Torch current rating
• Torch cable length
• Cooling type
• Connector type
• Compatible contact-tip sizes
• Compatible gas nozzle
• Duty-cycle rating

The correct replacement consumables should be published once verified.

Earth Clamp Included

The live product page lists an earth clamp in the package.

Connect the earth clamp to clean, bare metal close to the welding area. Paint, rust, scale, oil and contamination may weaken the electrical connection and affect arc stability.

Confirm the earth-clamp cable length, conductor size and current rating.

Connector Cables Included

The live page lists connector cables under the package contents.

These may be interconnecting cables used between the main power source and external wire feeder. Verify:

• Number of cables
• Cable length
• Cable cross-sectional area
• Connector type
• Control-cable configuration
• Gas-hose inclusion
• Maximum current rating

Heavy Industrial Construction

The machine has a listed net weight of 30kg and dimensions of 560 , 290, 530mm. The live page describes it as having a heavy industrial build.

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

Suitable for Heavy Fabrication

Heavy fabrication is one of the primary use cases listed on the product page.

The machine may be suitable for compatible fabrication applications involving:

• Structural assemblies
• Machinery frames
• Industrial equipment
• Workshop fabrication
• Construction components
