1. Introduktion og overview
The Sealey MIGHTYMIG150 is a professional-grade compact MIG welder designed for both gas and gasless operation, offering excellent performance for a variety of welding tasks. This unit is versatile and can be easily switched between gasless and gas modes by a simple change of polarity and the addition of a Gas Conversion Kit (Model No. 120.802032, sold separately).
This manual provides essential information for the safe and efficient use of your MIGHTYMIG150 welder. Please read it thoroughly before operation.
2. Sikkerhedsoplysninger
WARNING: Welding can be dangerous. Always follow safety precautions to prevent injury or damage.
- Personligt beskyttelsesudstyr (PPE): Always wear appropriate PPE, including a welding helmet with proper shade, flame-resistant clothing, welding gloves, and safety shoes. Protect bystanders with welding screens.
- Ventilation: Ensure adequate ventilation to remove welding fumes, which can be hazardous. Work in a well-ventilated area or use fume extraction equipment.
- Elektrisk sikkerhed: Ensure the power supply is correctly rated for the welder (230V). Do not operate in damp conditions. Inspect cables and connections for damage before each use.
- Brandforebyggelse: Keep flammable materials away from the welding area. Have a fire extinguisher readily available. Hot metal and sparks can cause fires.
- Bue stråler: Arc rays can cause eye and skin burns. Never look at the welding arc without proper eye protection.
- Røg og gasser: Avoid breathing welding fumes and gases. They can be harmful to your health.
- Arbejdsområde: Hold arbejdsområdet rent og frit for rod. Sørg for et stabilt fodfæste.
3. Pakkens indhold
Ved udpakning skal du kontrollere, at alle følgende varer er inkluderet:
- Sealey MIGHTYMIG150 Welder Unit
- Comfort Grip Non-Live Torch (2.1 mtr)
- Earth Cable (1.8 mtr)
- Gas Hose (1 mtr)
- Flux Cored Wire (0.45 kg)
- 1 mm kontaktspids
Note: A power plug is not supplied and must be fitted by a qualified person according to local regulations.
4. Opsætningsvejledning
4.1. Indledende opsætning
- Unpack the welder and place it on a stable, level surface.
- Sørg for, at tænd/sluk-knappen er i 'OFF'-positionen.
- Tilslut jord clamp to the designated terminal on the front panel.
- Connect the welding torch cable to the 'TORCH' connection point.
- Install the wire spool (0.9kg gasless or 0.7kg mild steel wire reels only) into the wire feed mechanism, ensuring it feeds smoothly through the guide tube and into the torch liner.
- Fit the appropriate contact tip to the torch.
4.2. Gasless Mode Setup
The unit is set up ready for gasless mode. For gasless welding, ensure the polarity is set correctly. The flux-cored wire typically requires DC electrode negative (DCEN) polarity. Refer to the polarity diagram inside the wire feed compartment if unsure.

4.3. Gas Mode Setup (Optional)
To switch to gas mode, a Gas Conversion Kit (Model No. 120.802032) is required. Follow these steps:
- Change the polarity to DC electrode positive (DCEP) for solid wire and shielding gas. Consult the polarity diagram.
- Connect the supplied gas hose to the welder's gas inlet and to your gas regulator (not supplied) on the gas cylinder (CO2, Argon, or CO2/Argon Mix).
- Sørg for, at alle gasforbindelser er sikre og lækagefri.
- Use appropriate solid welding wire for gas welding.

5. Betjeningsvejledning
5.1. Tænder
- Ensure all connections are secure and the work area is safe.
- Connect the welder to a suitable 230V power supply.
- Turn the 'POWER' switch to the 'ON' position. The 'POWER ON' indicator light should illuminate.
5.2. Indstilling af svejseparametre
- Strømindstillinger: The MIGHTYMIG150 has multiple power settings (MIN/MAX, 1/2). Select the appropriate setting based on the thickness of the material being welded. Start with lower settings for thinner materials and increase for thicker materials.
- Trådhastighed: Adjust the 'WIRE SPEED' dial (1-10) to control the rate at which the welding wire feeds. A good starting point is to match the wire speed to the power setting to achieve a smooth, consistent arc.
5.3. Svejseprocedure
- Fastgør jordklemmen sikkertamp til emnet, hvilket sikrer god elektrisk kontakt.
- Position the torch nozzle approximately 10-15mm from the workpiece.
- Press the torch trigger to initiate the arc and wire feed.
- Maintain a consistent travel speed and torch angle for a uniform weld bead.
- Slip aftrækkeren for at stoppe svejsningen.

6. Vedligeholdelse
Regelmæssig vedligeholdelse sikrer din svejsemaskines lange levetid og sikker drift.
- Rensning: Regularly clean the welder, especially the wire feed mechanism, to remove dust and debris. Use compressed air to clear ventilation slots.
- Kontakttip: Inspect and replace the contact tip regularly as it wears out. A worn tip can lead to poor arc stability and wire feeding issues.
- Torch Liner: Periodically check the torch liner for blockages or wear. A damaged liner can cause wire feeding problems.
- Jord Clamp: Sørg for jorden clamp is clean and makes good contact with the workpiece.
- Kabler: Inspect all cables for cuts, abrasions, or damage. Replace damaged cables immediately.
- Opbevaring: Opbevar svejsemaskinen et tørt og rent sted, når den ikke er i brug.
7. Fejlfinding
If you encounter issues with your MIGHTYMIG150 welder, refer to the following common troubleshooting tips:
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Ingen strøm til enheden | Strømkabel frakoblet, afbryder udløst, defekt strømafbryder. | Check power cable connection, reset circuit breaker, contact qualified technician if switch is faulty. |
| Tråden fremføres ikke | Wire spool tangled, contact tip blocked, torch liner clogged, wire feed motor issue. | Untangle wire, clean/replace contact tip, clear/replace torch liner, check wire feed motor connection. |
| Poor weld quality / Inconsistent arc | Incorrect power/wire speed settings, poor earth connection, wrong polarity, contaminated workpiece. | Adjust settings, clean earth clamp contact, verify polarity, clean workpiece thoroughly. |
| Termisk overbelastningslampe lyser | Exceeded duty cycle, insufficient cooling. | Allow the unit to cool down. Ensure ventilation is not obstructed. |
If problems persist after attempting these solutions, please contact Sealey customer support or a qualified service technician.
