Product Description
Product Description
XLNT MMA300-3B IGBT ARC Inverter Welding Machine
The XLNT MMA300-3B is a dual-voltage IGBT ARC inverter welding machine designed for heavy welding, fabrication, repair and maintenance applications. It provides a published adjustable welding-current range of 50-180A and supports a listed 220V/380V 15% input.
The machine is listed with 85% efficiency, a 0.93 power factor, Class F insulation and IP21 protection. It is supplied with a 3-metre earth-clamp cable and a 3-metre electrode-holder cable. The current product page positions it for workshops, industrial welders and fabricators.
50-180A Adjustable Welding Output
The XLNT MMA300-3B provides a published output-current range of 50-180A.
The correct current setting depends on:
- Electrode diameter
- Electrode type
- Base-metal thickness
- Joint design
- Welding position
- Material condition
- Required penetration
- Electrical-supply stability
- Duty-cycle limitation
The supported electrode sizes and electrode types are not currently stated. These should be confirmed before adding an electrode-selection chart.
300A Model Name Requires Clarification
The website names the product as a 300A ARC welding machine, but its technical specification lists only 50-180A output.
Recommended wording:
Model Positioning: 300A
Published Technical Output Range: 50-180A
Do not state that the machine delivers 300A unless the manufacturer‚rating plate and documentation confirm it.
220V/380V Dual-Voltage Input
The machine supports a listed input voltage of 220V/380V ±15% at 50/60Hz. The supplied image lists a rated input current of 20A, while the website identifies the machine as dual-voltage.
Before installation, verify:
- Whether voltage selection is automatic or manual
- Whether 220V operation is single-phase
- Whether 380V operation is three-phase
- Input-current requirement for each voltage
- Recommended MCB or MCCB
- Plug and socket rating
- Input-cable size
- Earthing requirement
- Power-cable length
The machine should not be connected until its voltage and phase configuration are confirmed from the physical rating plate.
Rated Input Current
The supplied specification image lists:
Rated Input Current: 20A
Confirm whether this applies to:
- 220V operation
- 380V operation
- Both voltage modes
- A particular welding-current setting
Dual-voltage machines may have different input-current requirements at each voltage.
Listed 4.5 kVA Capacity
The live website lists a rated capacity of 4.5 kVA.
The supplied image appears to show ‚4.5KVA which is likely a formatting issue. Use:
Rated Capacity: 4.5 kVA
Confirm the value from the physical rating plate before giving electrical-installation recommendations.
80/70V Listed No-Load Voltage
The supplied image lists:
Output No-Load Voltage: 80/70V
The image does not explain whether:
- 80V applies to 220V input
- 70V applies to 380V input
- The values refer to different operating modes
Recommended temporary wording:
Listed No-Load Voltage: 80/70V — operating-mode relationship to be confirmed
No-load voltage is present while the machine is powered on, but no arc is being produced. Avoid touching exposed terminals, electrodes or conductive welding components.
Listed 40% Duty Cycle
The supplied specification image lists a load duration of 40%, which should be presented as:
Listed Duty Cycle: 40%
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 output current used for testing
- The test temperature
- The applicable technical standard
- The required cooling period
Do not claim 180A or 300A at a 40% duty cycle unless officially confirmed.
Listed 85% Efficiency
The XLNT MMA300-3B has a listed efficiency of 85%. This is also displayed in the website product highlights.
The applicable testing standard is not stated. Avoid comparing the efficiency directly with other machines unless they were tested under equivalent conditions.
0.93 Power Factor
The supplied image and website list a power factor of 0.93.
This value is useful for professional buyers and electrical-installation planning.
IGBT Inverter Technology
The live product page identifies the machine as an IGBT inverter welder and highlights stable arc output.
IGBT inverter construction supports a more compact design compared with many traditional transformer-type welding machines.
Do not add the following functions unless verified:
- Hot start
- Arc force
- Anti-stick
- VRD
- Thermal overload protection
- Lift TIG
- Digital voltage display
Digital Welding Control Panel
The supplied product image appears to show:
- Digital display
- Welding-current adjustment
- Status indicators
- Front output connectors
Confirm whether the display shows:
- Selected current
- Actual welding current
- Voltage
- Error codes
- Thermal warning
Until verified, use:
Digital Welding Control Panel
ARC and MMA Welding Applications
The product URL and title identify it as an ARC welding machine, while the model name uses MMA300-3B.
Suitable terminology may include:
- ARC welding machine
- MMA welding machine
- Stick welding machine
- Manual electrode welder
- Inverter welding machine
Do not advertise MIG or TIG welding functions unless separately confirmed.
Suitable for Heavy Welding
The live page lists heavy welding as one of the main use cases.
Actual suitability depends on:
- Verified maximum output
- Electrode size
- Electrode type
- Material thickness
- Electrical supply
- Duty cycle
- Welding procedure
Avoid describing it as a 300A heavy-duty welder until the physical output rating is verified.
Suitable for Fabrication
Fabrication is another listed application.
The machine may be used for suitable:
- Workshop fabrication
- Equipment repair
- Steel bracket welding
- Gate and grill work
- Agricultural-equipment repair
- General metal maintenance
- Fabricated assemblies
Suitable for Maintenance Work
Maintenance work is also listed as an intended application. The product is positioned for workshops, industrial welders and fabricators.
Compact 7kg Construction
The supplied specification image lists:
Net Weight: 7kg
Dimensions: 320 √ó 160 √ó 280mm
This supports easier handling and transportation between workshops and repair locations.
Confirm whether the dimensions refer to:
- Machine dimensions
- Carton dimensions
- Shipping dimensions
IP21 and IP21S Protection
The website lists IP21 ingress protection, while the supplied image includes both IP21S shell enclosure rating and IP21 housing protection.
Recommended temporary wording:
Housing Protection: IP21
Shell Enclosure Rating: IP21S, as shown in supplied specification
Confirm whether both ratings apply to the complete machine.
IP21 does not mean the machine is waterproof. Protect it from rain, direct water spray, standing water and wet workshop floors.
Class F Insulation
The supplied image lists Class F insulation.
Include this in the technical specifications, but do not use it to claim a specific maximum operating temperature without official documentation.
3m Earth-Clamp Cable Included
The website and supplied image confirm an earth clamp with a 3-metre cable.
Connect the clamp to clean, bare metal near the welding area. Remove paint, rust, scale, grease or contamination where necessary.
3m Electrode-Holder Cable Included
The package also includes an electrode holder with a 3-metre cable.
Inspect the holder, insulation, terminals and cable before every use. Do not operate the machine if the cable is cut, melted, exposed or damaged.
How to Use
