4. Persediaan
4.1. Sambungan Kuasa
Connect the welder to a suitable 240V (or 110V/220V compatible) power outlet. Ensure the power supply matches the welder's requirements to prevent damage.
4.2. Pemasangan Wayar
The MIG250 supports various welding wire types and diameters, including 0.6mm, 0.8mm, 0.9mm, and 1.0mm solid wire, as well as 0.8mm and 1.0mm aluminum wire. It can accommodate 1kg or 5kg spools of filler wire.
- Buka petak kili wayar.
- Letakkan gelendong wayar pada gelendong, pastikan ia berputar dengan bebas.
- Thread the welding wire through the wire feed mechanism, ensuring it passes through the correct groove on the feed roller for the chosen wire diameter.
- Close the compartment and adjust the wire tension as needed.

4.3. Gas Connection (for MIG with Gas)
For MIG welding with gas (MIG CO2 or MIG MIX), connect the gas hose from your gas cylinder to the gas inlet on the welder. Ensure all connections are secure and leak-free. Use appropriate shielding gas for your welding application (e.g., CO2 for steel, Argon/CO2 mix for stainless steel).
4.4. Obor dan Tanah Clamp Sambungan
Connect the MIG torch to the designated MIG torch output. Connect the ground clamp cable to the ground terminal and securely attach the clamp ke bahan kerja, memastikan sentuhan elektrik yang baik.
5. Mod Operasi
The HITBOX MIG250 offers multiple welding processes. Select the desired mode on the control panel.
5.1. Kimpalan MIG (Gas/Tanpa Gas)
MIG welding is suitable for various metals including iron, stainless steel, alloy steel, carbon steel, cadmium metal, cadmium-copper metal, and aluminum-magnesium metal. The current range for MIG welding is 30-180A, with a voltage adjustment range of 11-26V.
- MIG CO2: Uses CO2 shielding gas for welding steel.
- MIG MIX: Uses a mixed shielding gas (e.g., Argon/CO2) for various metals.
- Flux Cored (Gasless MIG): Uses flux-cored wire, eliminating the need for external shielding gas.
- Mod 2T/4T: Select 2T for short, intermittent welds or 4T for longer, continuous welds.
- Kawalan Induktans: Adjust the inductance effect to fine-tune the arc width and improve weld quality.
5.2. ARC/MMA Welding
The MMA mode supports welding with electrodes from 1.6mm to 4.0mm in diameter, with a current range of 30-180A. Common electrode types like 6013 and 7018 are supported.
- Fungsi VRD: The built-in VRD (Voltage Reduction Device) enhances safety by reducing the open-circuit voltage when not welding.
- Anti-Stick Process: Prevents the electrode from sticking to the workpiece, ensuring smoother arc initiation.
5.3. Angkat Kimpalan TIG
The Lift TIG mode offers a current range of 20-180A. This machine uses a scratch-start (Lift TIG) ignition method.
- Fungsi VRD: The VRD light illuminates in Lift TIG mode to prevent the tungsten needle from sticking to the workpiece.
- Obor TIG: A TIG torch is not included and must be purchased separately. Gas for TIG welding must be connected directly to the TIG torch, as there are no dedicated gas connections for TIG on the machine.
6. Penyelenggaraan
Penyelenggaraan tetap memastikan umur panjang dan prestasi optimum pengimpal anda.
- Pembersihan: Periodically clean the welder's exterior and internal components (if accessible and safe to do so) to remove dust and debris. Use compressed air for internal cleaning.
- Pemeriksaan Kabel: Regularly inspect all welding cables, torches, and ground clamps for cuts, fraying, or damage. Replace damaged components immediately.
- Sistem Suapan Kawat: Check the wire feed rollers and liner for wear. Clean any debris from the wire feed path to ensure smooth wire delivery.
- Nozzles and Contact Tips: Replace MIG nozzles and contact tips as they wear out to maintain consistent arc performance.
- Storan: Simpan mesin kimpal di persekitaran yang bersih dan kering apabila tidak digunakan.
