4. Setup
4.1. Connecting the Welding Cables
- Ensure the welder is turned off and unplugged from the power source.
- Connect the electrode holder cable to the positive (+) terminal on the front panel. Twist clockwise to secure.
- Connect the ground clamp cable to the negative (-) terminal on the front panel. Twist clockwise to secure.
- Attach the ground clamp securely to the workpiece or a metal workbench that is in direct contact with the workpiece. Ensure good electrical contact.
- Insert a suitable electrode into the electrode holder.
4.2. Power Connection
- Ensure the power switch on the welder is in the 'OFF' position.
- Connect the welder's power cord to a suitable power outlet (230V, 50/60Hz). Ensure the outlet is properly grounded and can handle the required current.
4.3. Installing the Welding Helmet
Assemble the welding helmet according to its separate instructions. Ensure the protective lenses are clean and correctly installed before use. Always wear the helmet when welding to protect your eyes and face from arc rays and sparks.
5. Operating Instructions
5.1. Basic Operation Steps
- Adjust Welding Current: Turn the control knob (1) to set the desired welding current (amperage) on the LED display.
- Select Electrode Diameter: Based on the adjusted current, the welder will indicate the recommended electrode diameter (2). Ensure you are using an electrode of the correct size.

5.2. Electrode Selection and Current Settings
The ARC 160 is suitable for both basic (alkaline) and rutile (acidic) welding electrodes. Refer to the table below for recommended current ranges based on electrode diameter:
| Electrode Diameter | Recommended Current Range |
|---|---|
| 2.0 mm | 50 - 80 A |
| 2.5 mm | 70 - 100 A |
| 3.2 mm | 110 - 140 A |

5.3. Welding Techniques
The ARC 160's features assist in achieving quality welds:
- Hot Start: Provides an initial surge of current to make arc ignition easier, especially with difficult-to-start electrodes.
- Arc Force: Automatically increases current when the arc length becomes too short, preventing the arc from extinguishing and maintaining stability.
- Anti-Stick: Reduces the welding current if the electrode sticks to the workpiece, allowing for easier removal without damaging the electrode or the machine.
