4. Setup
4.1. Power Connection
- Ensure the welding machine's power switch is in the "OFF" position.
- Connect the power cord to a suitable 220V ±15%, 50/60Hz power outlet. Ensure the power source can provide the required 7.2KVA input.
4.2. Cable Connections
- Connect the electrode holder cable to the positive (+) quick connector socket on the front panel.
- Connect the earth clamp cable to the negative (-) quick connector socket on the front panel.
- Securely attach the earth clamp to the workpiece or welding table, ensuring good electrical contact.
- Insert the welding electrode into the electrode holder.
5. Operating Instructions
5.1. Basic Operation
- After connecting all cables and ensuring safety, turn the power switch to the "ON" position. The digital display will light up.
- Adjust the welding current using the "Current Adjusting Knob" according to the electrode size and material thickness. The digital display will show the set amperage.
- Adjust the "Arc Force Regulator" as needed. Higher arc force can prevent the electrode from sticking and improve penetration.
