XLNT ARC 400IC 400A Industrial ARC Inverter Welding Machine
The XLNT ARC 400IC is a high-output industrial inverter welding machine designed for heavy-duty ARC welding, fabrication, maintenance and professional workshop applications. It provides a listed adjustable output-current range of 30-400A, allowing the operator to choose an appropriate current according to the electrode, base-metal thickness, joint design and welding requirement.
The machine operates on a listed 415V ±15% electrical input at 50/60Hz. It has a rated input current of 44.7A, a listed 60% duty cycle, 85% efficiency, 0.93 power factor, Class F insulation and IP21 housing protection.
The live product page identifies industrial welders, maintenance teams and fabricators as the main users and lists heavy-duty welding, maintenance work and fabrication jobs as its primary applications.
30-400A Adjustable Welding Output
The XLNT ARC 400IC provides a listed welding-current range of 30-400A.
The correct current setting depends on:
- Electrode diameter
- Electrode type
- Base-metal thickness
- Joint preparation
- Welding position
- Material condition
- Required penetration
- Electrical-supply stability
- Duty-cycle limitation
- Operator technique
The machine's supported electrode diameters and electrode types are not currently published. These should be confirmed before adding an electrode-selection chart.
400A Maximum Listed Welding Current
The machine is marketed as a 400A ARC welding machine, and the supplied specification image lists an output-current range reaching 400A.
Recommended catalogue wording:
Maximum Listed Welding Current: 400A
Do not claim continuous 400A welding unless the manufacturer supplies a duty-cycle chart that clearly states the allowable operating duration at 400A.
415V Industrial Electrical Input
The XLNT ARC 400IC requires a listed 415V ±15% electrical supply.
This voltage generally indicates an industrial installation, but the physical rating label must confirm whether the machine requires three-phase power before connection.
Before installation, verify:
- Phase configuration
- Input-cable size
- Earthing requirement
- Recommended MCB or MCCB
- Industrial plug and socket rating
- Isolation-switch requirement
- Power-cable length
- Maximum input current
- Supply voltage stability
This machine should not be connected to a normal 220V household socket.
Electrical installation should be completed or checked by a qualified electrician.
Rated Input Current of 44.7A
The supplied specification image lists a rated input current of 44.7A.
This is an important electrical installation specification. However, confirm whether 44.7A represents:
- Rated input current at maximum output
- Maximum input current
- Current drawn at the stated duty cycle
- Current per phase
- Current under a specified test condition
Do not recommend an MCB, MCCB or supply-cable size based only on this number without checking the physical rating plate and installation manual.
65V No-Load Voltage
The supplied specification lists a no-load voltage of 65V.
No-load voltage is present when the machine is switched on but an arc is not being produced. Operators must avoid contact with exposed terminals, electrode holders and conductive welding components while the machine is energised.
The rated output voltage is not stated and should be added after verification.
Listed 60% Duty Cycle
The XLNT ARC 400IC has a listed duty cycle of 60%.
Duty cycle indicates how long the machine may weld within a defined test period before cooling is required.
The available information does not state:
- The current at which the duty cycle was tested
- The ambient test temperature
- The applicable testing standard
- The required cooling period
Use:
Listed Duty Cycle: 60%
Do not publish “400A at 60% duty cycle” unless official documentation confirms that exact rating.
Listed 85% Efficiency
The welding machine has a listed efficiency of 85%.
This specification can be included in the technical table, but direct comparisons with other welding machines should be avoided unless all machines were tested under the same technical standard and conditions.
0.93 Power Factor
The ARC 400IC has a listed power factor of 0.93.
This is useful information for industrial electrical planning and should be retained in the product specifications.
Digital Welding Control Panel
The supplied product image appears to show a digital control panel with separate displays and adjustment controls.
Confirm whether the controls provide adjustment for:
- Welding current
- Arc-force setting
- Hot-start current
- Hot-start duration
- Electrode diameter
- Welding mode
- Error codes
- Thermal warning
Until the functions are verified, use the general wording:
Digital Welding Control Panel
Do not claim specific hot-start, arc-force or anti-stick functionality based only on the appearance of the control panel.
ARC and MMA Welding Applications
The machine is identified as an ARC welding machine. Confirm whether the manufacturer also officially classifies it as an MMA or stick welding machine.
If confirmed, suitable terminology may include:
- ARC welding machine
- MMA welding machine
- Stick welding machine
- Manual electrode welder
- Industrial inverter welder
Do not advertise MIG or TIG welding functionality unless separately verified.
Heavy-Duty Industrial Fabrication
The ARC 400IC is designed for higher-output fabrication and maintenance applications where a compatible industrial electrical supply is available.
Potential uses include:
- Heavy metal fabrication
- Machinery-frame welding
- Industrial maintenance
- Workshop production
- Equipment repair
- Structural component fabrication
- Construction-site maintenance
- Agricultural-equipment repair
- Industrial steelwork
Suitability depends on the electrode, material thickness, welding procedure, duty cycle and electrical installation.
Maintenance and Repair Welding
The live page lists maintenance work among the intended applications.
The adjustable output may support compatible repair work involving:
- Industrial equipment
- Machinery frames
- Metal structures
- Workshop fixtures
- Construction equipment
- Steel brackets
- Fabricated assemblies
Certified structural or safety-critical welding must follow an approved welding procedure and applicable inspection requirements.
Compact 16.5kg Industrial Body
The supplied specification image lists a machine net weight of 16.5kg and dimensions of 545 x 350 x 460 mm.
Although it is lighter than some transformer-based industrial welders, controlled lifting is recommended. Use the carrying handles correctly and consider two-person handling when moving the machine across uneven working areas.
Confirm whether the listed dimensions refer to:
- Machine dimensions
- Carton dimensions
- Shipping-package dimensions
IP21 Housing Protection
The welding machine has a listed IP21 protection rating.
IP21 does not mean that the machine is waterproof. Keep it protected from:
- Rain
- Standing water
- Direct water spray
- Wet workshop floors
- Damp storage
- Excessive grinding dust
- Conductive metal particles
Keep the ventilation openings clean and unobstructed during use.
Class F Insulation
The supplied specification lists Class F insulation.
This specification should remain in the technical table, but it should not be used to claim a particular maximum operating temperature unless the manufacturer provides supporting documentation.
Welding Accessories Require Confirmation
The supplied specification table does not list any included accessories. The live page only states ‚customizable accessories, which is too vague for a professional welding-machine listing.
Before publication, physically verify whether the package includes:
- Electrode holder
- Electrode-holder cable
- Earth clamp
- Earth-clamp cable
- Welding connectors
- Power cable
- Industrial plug
- Remote controller
- Welding mask
- Wire brush
- User manual
- Warranty card
Do not show any accessory as included until the carton is checked.
