Key specifications
Welding current range: 20A to 300A
Welding type: Manual metal arc (MMA)
Technology: Inverter-based power source
How to use
Ensure the work area is clean, well-ventilated, and free from flammable materials before starting. Connect the electrode holder and the earth clamp to the appropriate terminals on the welder according to the polarity requirements of the chosen electrodes. Plug the power cord into a suitable electrical outlet and switch on the device. Adjust the current control knob to the desired amperage level based on the thickness of the metal and the electrode diameter. Position the earth clamp securely on the workpiece, strike the arc using the electrode, and maintain a consistent angle and travel speed while welding.
What to consider before purchase
Verify that your power supply matches the electrical requirements of the welder
Consider the maximum metal thickness you plan to weld to ensure the 300A upper limit meets your project demands
Ensure you have the necessary safety equipment, including a welding helmet, gloves, and protective clothing
Usage recommendations: Always wear appropriate personal protective equipment, including a certified welding helmet and heat-resistant gloves, during operation. Operate the machine in a dry environment and allow adequate ventilation space around the housing to prevent overheating during extended use.
