Important reminder:
During the welding and cutting process, the function switch cannot be switched to avoid damaging the machine.
Before cutting, the quick plug connected to the welding pliers must be unplugged to ensure that the pliers are disconnected from the main machine to prevent electric shock.
3. To use this device, a leakage safety switch needs to be installed!
4. Use welding labor protection equipment recognized by the national security supervision department!
The operator must be a special operator with a valid Metal Welding (Gas Cutting) Operation Certificate!
Electric shock - can cause serious injury!
Install the grounding device according to the application standards.
When the skin is exposed, wet gloves are worn, or wet clothes are worn, contact with live parts or welding electrodes is prohibited.
Ensure that you are insulated from the ground and the workpiece.
9. Confirm that your workstation is in a safe state.
Smoke - can be harmful to health!
Keep your head outside the smoke.
During arc welding, use ventilation or extraction devices to avoid inhaling smoke.
Arc radiation - can damage your eyes and burn your skin!
Use appropriate welding masks and filters, wear protective clothing to protect your eyes and body.
Use suitable masks or curtains to protect bystanders from injury.
Fire - Welding sparks may cause a fire. Please confirm that there are no flammable materials near the welding station and pay attention to safety and fire prevention.
Noise - Excessive noise is harmful to human hearing
13. Protect your ears by using ear shields or wearing other hearing protectors.
14. Warn bystanders that noise can potentially harm their hearing.
Fault - seek professional help when encountering difficulties.
If you encounter difficulties during installation and operation, please follow the relevant content of this manual for troubleshooting.
Introduction to DC arc welding machine
This welding machine is manufactured using advanced inverter technology. The inverter power supply uses high-power device V-MOS field-effect transistors to convert the working frequency of 50/60Hz to high frequency (such as 100KHZ or above), then step-down rectification, and outputs a high-power DC source through pulse width modulation technology (PWM). The weight and volume of the main transformer are greatly reduced, and the efficiency is increased by more than 30%. The arc ignition system adopts the principle of high-frequency oscillation. Its characteristics: stable, reliable, lightweight, energy-saving, and no electromagnetic noise.
The characteristics of the hand arc welding machine series are: high efficiency, energy saving, lightweight, and good dynamic characteristics, stable arc, and easy control of the molten pool. Higher no-load voltage and better energy thrust compensation. Widely used, it can be used for high-altitude operations, outdoor operations, indoor and outdoor decoration, etc. Compared with similar domestic products, it has the characteristics of small volume, light weight, easy installation, and easy operation.
