6. Mod dan Fungsi Operasi

The HBT250P offers multiple welding modes and adjustable parameters for various welding tasks.

6.1. Welding Mode Selection

Figure 5: Detailed Control Panel Functions for Mode Selection.

• MMA (ARC) Welding Mode: For stick electrode welding. Suitable for carbon steel, stainless steel, and cast iron. Welding wire diameter: 2.5/3.2/4.0 mm. Welding thickness: 2-12 mm.
• TIG Welding Mode: For Gas Tungsten Arc Welding. Offers precise control and high-quality welds.
  • AC TIG: Ideal for welding aluminum and its alloys.
  • DC TIG: Suitable for stainless steel, carbon steel, copper, titanium, and other non-ferrous metals.
  • Pulse TIG: Provides better control over heat input, reducing distortion and improving weld quality, especially on thin materials.
  Welding wire diameter for TIG: 1.6/2.4/3.2 mm. Welding thickness for TIG: 1.2-4 mm.

6.2. Fungsi 2T/4T

• 2T (Manual Mode): Press and hold the torch trigger to weld; release to stop. Ideal for short welds.
• 4T (Semi-automatic Mode): Press and release the trigger to start welding; press and release again to stop. Convenient for longer welds, reducing hand fatigue.

6.3. Pelarasan Parameter

The adjustment knob and parameter knob allow fine-tuning of various settings:

• Amppemadaman: Controls the welding current (10-200A for TIG, 20-120A for MMA).
• Kawalan Masa: For pre-flow, post-flow gas, up-slope, and down-slope times in TIG welding.
• Kekerapan: Adjusts the AC frequency for aluminum welding.
• Kitaran Tugas: Controls the balance between peak and base current in pulse welding.
• Baki AC: Adjusts the cleaning action and penetration when welding aluminum in AC TIG mode.

The machine offers continuous adjustment for these parameters, allowing for precise control over the welding process.

7. Penyelenggaraan

Penyelenggaraan berkala memastikan jangka hayat dan operasi mesin kimpalan anda yang selamat.

• Pembersihan: Regularly clean the machine's exterior with a dry, soft cloth. Use compressed air to blow out dust from the cooling vents. Do not use solvents.
• Pemeriksaan Kabel: Periodically check all welding cables, connections, and the power cord for damage, fraying, or loose connections. Replace damaged parts immediately.
• Torch and Clamp Penyelenggaraan: Inspect the TIG torch and electrode holder for wear and tear. Clean or replace consumables (tungsten electrodes, nozzles, collets) as needed. Ensure the earth clamp makes good contact with the workpiece.
• Storan: Store the welding machine in a dry, clean, and well-ventilated area, away from direct sunlight, moisture, and corrosive substances.
• Pemeriksaan Dalaman: For internal cleaning or inspection, it is recommended to consult a qualified technician.

9. Petua Pengguna

• Kawalan Pedal Kaki: For enhanced control over welding current, consider using an optional foot pedal. This allows for hands-free current adjustment during TIG welding.
• Tungsten Electrodes: Always use the correct type and size of tungsten electrode for your material and welding process. Ensure the tungsten is properly ground for optimal arc stability.
• Tetapan Nadi: Experiment with pulse frequency and duty cycle settings to find the ideal parameters for thin materials or when minimizing heat input is crucial.
• Aluminum Welding: When welding aluminum with AC TIG, pay attention to the AC balance setting. A higher cleaning action (more positive half-cycle) helps break up aluminum oxide, while more penetration (more negative half-cycle) increases weld depth.
• Alat Ganti: Keep a small stock of common consumables like tungsten electrodes, ceramic nozzles, and collets to avoid interruptions during welding projects.
