Product Description
Product Description
XLNT MMA300-1B IGBT ARC Inverter Welding Machine
The XLNT MMA300-1B is a compact IGBT ARC inverter welding machine designed for repair welding, fabrication, maintenance, indoor welding and suitable outdoor welding applications.
The live product page promotes wide-voltage input, IGBT inverter technology, smart fan cooling, a compact body and an energy-saving inverter system. It is positioned for workshops, maintenance teams and industrial users.
The supplied specification image lists an adjustable welding-current range of 40-230A, 220V/380V ±15% input, 50/60Hz frequency, 85% efficiency, 0.89 power factor, Class F insulation and IP21 housing protection.
Although the website promotes an output of up to 300A, the supplied technical specification reaches only 230A. Therefore, 300A should be treated as the model or marketed amperage until the physical rating plate confirms the actual output.
40-230A Adjustable Welding Output
The supplied technical image lists an adjustable output-current range of 40-230A.
The appropriate welding-current setting depends on:
- Electrode diameter
- Electrode type
- Base-metal thickness
- Joint preparation
- Welding position
- Material condition
- Required penetration
- Electrical-supply stability
- Verified duty cycle
- Operator technique
The compatible electrode sizes and electrode types are not stated. These should be confirmed before adding an electrode-selection chart.
300A Model Positioning
The live product page displays an output claim of up to 300A. However, the supplied technical table lists 40-230A.
Recommended catalogue wording:
Marketed Model Amperage: 300A
Published Technical Output Range: 40-230A
Do not describe the machine as producing a verified 300A welding output unless supported by the physical rating plate or manufacturer documentation.
220V/380V Dual-Voltage Input
The supplied image lists an input voltage of 220V/380V ±15% with a frequency of 50/60Hz. The live page also promotes a wide-voltage input range of 220-380V.
Before connecting the machine, confirm:
- Whether 220V operation is single-phase
- Whether 380V operation is three-phase
- Whether voltage selection is automatic or manual
- Input-current requirement at each voltage
- Recommended MCB or MCCB
- Required supply-cable size
- Plug and socket rating
- Earthing requirements
- Power-cable length
The machine should only be connected after checking the voltage and phase configuration on the physical rating label.
Rated Input Current Requires Verification
The supplied image appears to list a rated input current of 220A.
Because this value may be a catalogue or decimal-formatting error, it should not be published as a confirmed specification.
Use:
Rated Input Current: Verify from physical rating label
Do not recommend a circuit breaker, socket, plug or supply cable until the correct input current is known.
Listed 80/70V No-Load Voltage
The supplied specification lists an output no-load voltage of 80/70V.
The available information does not explain whether:
- 80V applies to the 220V input mode
- 70V applies to the 380V input mode
- The figures represent different operating conditions
Recommended temporary wording:
Listed No-Load Voltage: 80/70V; operating conditions to be confirmed
No-load voltage is present when the machine is powered on, but no welding arc is active. Avoid touching exposed terminals, electrodes or conductive welding components while the machine is energised.
Duty Cycle Requires Confirmation
The supplied specification image shows both a 60% rated load duration and a separate load-duration value of 40.
Because these figures conflict, use:
Duty Cycle: To be confirmed from physical rating label
The final duty-cycle specification should ideally state:
- Duty-cycle percentage
- Welding current used for testing
- Test temperature
- Required cooling period
- Applicable testing standard
Listed 85% Efficiency
The supplied technical image lists an efficiency of 85%.
The live product page also promotes the machine as using an energy-saving inverter system.
Avoid direct efficiency comparisons with other welding machines unless all products were tested under the same standard and operating conditions.
0.89 Power Factor
The supplied specification image lists a power factor of 0.89.
This specification is useful for electrical planning and can be included after checking it against the physical machine label.
IGBT Inverter Technology
The live product page confirms IGBT inverter technology. It also promotes a compact body and energy-saving inverter design.
Do not add the following functions unless individually verified:
- Hot start
- Arc-force control
- Anti-stick
- VRD
- Lift TIG
- Automatic voltage selection
- Thermal-overload protection
Smart Fan Cooling
The live product page lists a smart fan cooling system.
Smart fan cooling may help manage internal temperature during suitable welding operations. Keep all ventilation openings clean and unobstructed.
Confirm whether the fan:
- Runs continuously
- Activates according to temperature
- Continues operating after welding
- Includes an overheating indicator
Digital Welding Control Panel
The supplied product image appears to show a digital display and welding-current adjustment control.
Until the functions are confirmed, use:
Digital Welding Control Panel
Confirm whether the display shows:
- Selected welding current
- Actual welding current
- Voltage
- Error codes
- Thermal warning
- Protection status
Compact 8.5kg Construction
The supplied image lists:
Net Weight: 8.5kg
Dimensions: 470 x 220 x 320 mm
The built-in handle and compact design support easier movement between workshops, maintenance areas and suitable job sites.
Confirm whether the listed dimensions refer to the machine or shipping carton.
Suitable for Repair Welding
Repair welding is listed as one of the main applications on the live page.
The machine may be used for compatible repairs involving:
- Gates and grills
- Metal brackets
- Machinery frames
- Workshop equipment
- Agricultural equipment
- Fabricated assemblies
- General steel fixtures
Actual suitability depends on the electrode, metal thickness, output setting and verified duty-cycle rating.
Suitable for Fabrication
Fabrication is another listed application. The machine can be considered for compatible workshop fabrication and general metal-joining work.
Do not promote it for safety-critical structural welding unless its output, electrode compatibility and welding procedure are formally approved.
Suitable for Indoor and Outdoor Welding
The live page lists both indoor welding and outdoor welding as intended use cases.
For outdoor use:
- Protect the machine from rain and moisture
- Use a stable electrical supply
- Maintain proper earthing
- Use correctly rated cables
- Keep ventilation openings unobstructed
- Protect the power and welding cables from damage
IP21 protection does not make the machine waterproof.
IP21 and IP21S Protection
The supplied specification image lists:
Shell Enclosure Rating: IP21S
Housing Protection Grade: IP21
Confirm whether both ratings apply to the complete machine.
Keep the welding machine protected from:
- Rain
- Direct water spray
- Standing water
- Wet floors
- Damp storage
- Conductive metal particles
- Excessive grinding dust
Class F Insulation
The supplied image lists Class F insulation.
Include this in the technical specifications, but do not use it to claim a particular maximum operating temperature without official manufacturer documentation.
