DEKO 135A-MIG 3-in-1 Inverter Arc Welder Instruction Manual

1. Safety Information

Always prioritize safety when operating welding equipment. Failure to follow safety guidelines can result in serious injury or death.

• Personal Protective Equipment (PPE): Always wear a welding helmet with appropriate shade, flame-resistant clothing, welding gloves, and safety shoes.
• Ventilation: Ensure adequate ventilation to avoid inhaling welding fumes, which can be hazardous.
• Fire Hazards: Keep flammable materials away from the welding area. Have a fire extinguisher readily available.
• Electrical Safety: Ensure the welder is properly grounded. Do not operate in wet conditions. Inspect cables for damage before use.
• Arc Rays: Welding arc rays can cause eye and skin burns. Protect yourself and bystanders.
• Hot Parts: Welded materials and equipment parts remain hot after welding. Handle with care.
• Overload Protection: The DEKO 135A-MIG welder includes over-current, over-voltage, overheating, and overload protection. If these activate, allow the machine to cool down before resuming operation.

3. Kit Contents

Your DEKO 135A-MIG welder package includes the following items:

• 1 x DEKO 135A-MIG Welder
• 1 x MIG Welding Torch (2 meters)
• 1 x Earth Clamp (2.1 meters)
• 1 x Flux-Cored Wire Spool
• 1 x Electrode Holder (2.1 meters)
• 1 x Nozzle
• 1 x 1.0/0.39 inch Nozzle
• 1 x Instruction Manual

4. Setup

4.1 Connecting Cables (MMA/Stick Welding)

1. Connect the electrode holder cable to the positive (+) terminal on the welder. Insert the connector and twist to secure.
2. Connect the earth clamp cable to the negative (-) terminal on the welder. Insert the connector and twist to secure.
3. Attach the earth clamp securely to the workpiece or welding table to ensure a good electrical connection.
4. Insert the welding electrode into the electrode holder.

4.2 Loading Flux-Cored Wire (MIG Welding)

1. Open the side panel of the welder to access the wire feed mechanism.
2. Place the flux-cored wire spool onto the spool holder. Ensure it rotates freely.
3. Thread the wire through the wire guide and into the drive roller mechanism.
4. Adjust the tension on the drive roller to prevent slipping or crushing the wire.
5. Close the side panel.

5. Operation

The DEKO 135A-MIG welder offers three primary welding modes: MIG (Flux-Cored), MMA (Stick), and Lift TIG.

Figure 5.1: The DEKO 135A-MIG supports MIG, Stick, and Lift TIG welding modes.

5.1 Selecting Welding Mode

Use the function selection button on the control panel (refer to Figure 2.3, item 1) to cycle through the available welding modes: MIG, MMA, or Lift TIG.

5.2 Adjusting Parameters

Once the mode is selected, use the adjustment knobs (refer to Figure 2.3, items 2 and 3) to set the appropriate voltage, current, or wire feed speed according to your material and welding requirements. The digital display (Figure 2.3, item 4) will show the selected values.

5.3 Welding Process

Ensure proper PPE is worn and the workpiece is securely clamped and grounded. Initiate the arc according to the chosen welding process. Maintain a steady hand and consistent travel speed for optimal weld quality.

5.4 Supported Materials

The DEKO 135A-MIG welder is capable of welding a wide range of metals, including:

Figure 5.2: Examples of metals that can be welded with the DEKO 135A-MIG: Cast Iron, Mild Steel, Sheet Metal, Stainless Steel, Square Pipe, and Metal Cage.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your DEKO 135A-MIG welder.

• Cleaning: Remove dust from the machine twice a month using compressed air. Ensure the machine is unplugged before cleaning.
• Cable Inspection: Periodically check all cables (electrode holder, earth clamp, power cord) for cuts, fraying, or damage. Replace damaged cables immediately.
• Nozzle and Contact Tip: For MIG welding, regularly clean or replace the nozzle and contact tip to ensure proper wire feed and gas flow.
• Storage: Store the welder in a dry, clean environment when not in use.

7. Troubleshooting

If you encounter issues with your DEKO 135A-MIG welder, consider the following common troubleshooting steps:

• No Power: Check the power connection, ensure the main switch is ON, and verify the power outlet is functional.
• No Arc: Ensure the earth clamp has a good connection to the workpiece. Check the electrode holder connection and that the electrode is properly inserted. For MIG, check wire feed and contact tip.
• Poor Weld Quality: Adjust welding parameters (current, voltage, wire speed) according to the material thickness and type. Ensure the workpiece is clean and free of rust or paint.
• Overload/Overheat Indicator: If the overload or overheat indicator lights up, stop welding and allow the machine to cool down. Ensure proper ventilation around the welder.
• Wire Feeding Issues (MIG): Check for tangled wire, proper tension on the drive rollers, and a clean contact tip/nozzle.

If problems persist, contact DEKO customer support for assistance.
