Gasless 180A MIG Welder & 200A Portable MMA Inverter Welding Machine from China Suppliers and Factory
Detailed Information
IGBT Inverter Gas Shielded Welding Machine
GMAW welding machine can perform melting electrode welding without gas protection. mainly uses the positive and negative polarity exchange,at the same time the use of FLUX core welding wire, and can use co2,as well as manual welding ,simple scratch argon arc welding function.
The rated Duty cycle refers to the amount of welding that can be done within an amount of time. It is easiest to look at your welding time in blocks of 10Minutes and the Duty Cycle being a percentage of that 10 Minutes. If welding at 155 Amps with a 60% Duty Cycle, within a 10 Minute block of time you can weld for 6 Minutes with 4 Minutes of cooling for the welder.
Operating methods
- After correct installation, turn on the power switch and push the power switch in the "ON" position. Then, the power indicator light will be on and the fan inside the welder will start rotating.
- According to the actual situation of use, the adapter is connected to the corresponding position,and the ground wire is firmly connected to the workpiece.
- According to the diameter of the welding wire, select the diameter of the contact tip of the welding gun.
- According to the thickness and process of the workpiece to be welded, cooperate with the "voltage adjustment" knob and "current adjustment" knob to the corresponding position.
- "Auto" mode can be selected, at this time it is a unified adjustment, only the current needs to be adjusted, and the voltage is automatically matched.
- In the "manual" mode, the current and voltage need to be adjusted separately, and the parameters can be manually matched to achieve a good welding process.
Main Features
- All movements adopt the latest and mature IGBT full-bridge inverter technology.
- IGBT inverter technology, less welding spatter and beautiful welding seams.
- Complete undervoltage, overvoltage and current protection, safe and reliable.
- Accurate digital display of current and voltage preset, easy and intuitive operation.
- High pressure and slow wire feeding to start the arc, the arc will not burst the wire, and the arc will be closed to remove small balls.
- Constant voltage output characteristics, CO2 welding, one machine for multiple purposes.
- Humanized, beautiful appearance design, more convenient to operate.
- Three-proof design for key parts, suitable for various harsh environments, with stable and reliable operation.

Frequently Asked Questions
What functions does this IGBT Inverter Gas Shielded Welding Machine offer?
This GMAW welding machine supports melting electrode welding without gas protection using positive and negative polarity exchange with flux core wire. It also supports CO2 welding, manual welding, and simple scratch argon arc welding.
How does the Duty Cycle affect my welding process?
The Rated Duty Cycle dictates the operational time within a 10-minute block. For example, a 60% Duty Cycle at 155 Amps allows you to weld continuously for 6 minutes, followed by 4 minutes of cooling for the welder.
What is the difference between "Auto" and "Manual" modes?
In "Auto" mode, a unified adjustment is used where you only adjust the current and the voltage matches automatically. In "Manual" mode, you adjust current and voltage separately to manually match parameters for your specific welding process.
What are the primary power and installation requirements?
The machine requires an input voltage of AC180-420V 50/60Hz, an input cable of ≥4mm² (length ≤3m), a 63A power switch, and an output cable of ≥25mm² (length ≤20m).
What ambient conditions should be maintained for safe operation?
The machine should be operated within a temperature range of -10℃ to +40℃. Ensure that the air inlet and outlet are not blocked, avoid direct sunlight exposure, pay attention to dust prevention, and fix the gas tank firmly in a cool place.
