1. Pengenalan
This manual provides essential information for the safe and effective operation of your HITBOX MT2000 200A 4-in-1 Multi-Process MIG Welder. Please read this manual thoroughly before operating the machine and retain it for future reference.
The HITBOX MT2000 is a versatile welding machine supporting multiple processes: Gas MIG, Flux Core MIG (Gasless MIG), Lift TIG, and Stick (MMA) welding. It is designed for various applications, from home DIY projects to outdoor repairs and light industrial use.
2. Maklumat Keselamatan
AMARAN: Kimpalan boleh berbahaya. Sentiasa patuhi langkah berjaga-jaga keselamatan untuk mencegah kecederaan atau kematian.
- Sentiasa pakai peralatan pelindung diri (PPE) yang sesuai, termasuk topi keledar kimpalan dengan pelindung matahari yang betul, pakaian tahan api, sarung tangan kimpalan dan kasut keselamatan.
- Pastikan pengudaraan yang mencukupi untuk mengelakkan terhidu asap kimpalan.
- Lindungi orang ramai daripada sinaran arka dan percikan api.
- Jangan sekali-kali mengimpal berhampiran bahan mudah terbakar.
- Pastikan mesin kimpalan dibumikan dengan betul.
- Putuskan sambungan kuasa sebelum melakukan sebarang penyelenggaraan atau menukar aksesori.
- Jangan sentuh bahagian hidup elektrik.

4. Persediaan
4.1 Sambungan Kuasa
- The welder supports both 110V and 220V power inputs. Use the provided 110V to 220V adapter if necessary.
- Ensure the power source matches the machine's requirements and is capable of handling the welding current.
4.2 Pemasangan Wayar (MIG/Teras Fluks)
- Open the wire feeder compartment.
- Letakkan gelendong wayar pada gelendong, pastikan ia berputar dengan bebas.
- Feed the welding wire through the guide tube and into the drive roller mechanism.
- Secure the drive roller tension arm. Adjust tension as needed; too tight can deform the wire, too loose can cause slipping.
- Ensure the correct drive roller groove (0.030" or 0.039") is aligned with your wire diameter.
- Tutup petak.

4.3 Obor dan Tanah Clamp Sambungan
- Kimpalan MIG: Connect the MIG gun to the appropriate connector on the front panel. Connect the ground clamp kepada benda kerja.
- Angkat Kimpalan TIG: Connect the TIG torch (WP17V TIG torch required, not included) to the negative (-) terminal. Connect the ground clamp ke terminal positif (+).
- Kimpalan Kayu (MMA): Sambungkan pemegang elektrod ke terminal positif (+) dan penutup pembumianamp to the negative (-) terminal for most electrodes (e.g., E6013). For E7018 electrodes, reverse the polarity (electrode holder to negative, ground clamp to positive).

5. Mod Operasi
The HITBOX MT2000 features a large color display for easy setting adjustments and mode selection.

5.1 MIG Welding (Gas & Gasless)
- Kawalan Sinergik: Ideal for beginners. Select the welding wire diameter, and the machine automatically adjusts recommended current and wire feeding speed for both 110V and 220V operations.
- Gas MIG: Requires shielding gas (e.g., CO2 or Argon/CO2 mix) for cleaner welds. Connect the gas hose to the machine and gas cylinder.
- Flux Core MIG (Gasless): Uses flux-cored wire that produces its own shielding gas, eliminating the need for an external gas cylinder.

5.2 Angkat Kimpalan TIG
- Requires a separate WP17V TIG torch and shielding gas (typically Argon).
- Initiate the arc by touching the tungsten electrode to the workpiece and then lifting it slightly.
5.3 Kimpalan Kayu (MMA).
- Use appropriate welding electrodes for your material and application.
- The machine features Hot Start, Arc Force, and Anti-stick functions for improved arc ignition and stability.
6. Ciri-ciri Perlindungan
The HITBOX MT2000 is equipped with multiple protection mechanisms to ensure safety and extend machine lifespan:
- Perlindungan lebihan arus: Mencegah kerosakan akibat tarikan arus yang berlebihan.
- Overvoltage Perlindungan: Perlindungan terhadap voltage lonjakan.
- Perlindungan Terlalu Panas: Shuts down the machine if internal temperatures become too high.
- Perlindungan Lebihan: Protects components from sustained heavy loads.
- Voltage Fluctuation Compensation: Ensures stable performance even with inconsistent power supply.

7. Penyelenggaraan
Regular maintenance ensures optimal performance and longevity of your welder:
- Keep the machine clean and free from dust and debris. Use compressed air to clear ventilation openings regularly.
- Inspect all cables and connections for damage before each use. Replace worn or damaged parts immediately.
- Check the MIG gun liner and contact tip regularly for wear and replace as needed to ensure consistent wire feeding.
- Ensure the drive rollers are clean and free of wire shavings.
