Viladepot MIG200 3-in-1 Welding Machine User Manual

1. 서론

The Viladepot MIG200 is an advanced Inverter MIG welding machine that combines three essential welding functions: MIG, Lift TIG, and MMA (Manual Metal Arc) welding. This versatile machine is suitable for welding various materials, including carbon steel, stainless steel, copper, and titanium.

It features IGBT high-frequency soft switch technology, ensuring high efficiency, a compact design, and portability. The advanced control system significantly enhances welding performance, providing easy arc starting, stable arc, high performance, minimal spatter, stable current, high reliability, and excellent weld-seam shaping.

Key Welding Modes:

• No Gas MIG: Utilizes flux-cored wires that generate their own shielding gas upon heating, eliminating the need for an external gas supply. This makes it ideal for outdoor use and welding thicker materials.
• MMA (Manual Metal Arc): Employs welding rods. An arc is formed when the electrode strikes the metal, melting both the electrode and the base metal. This process provides shielding gas and forms a protective slag layer over the weld. MMA is highly versatile, performs well outdoors, and is commonly used for maintenance, repair, and construction tasks.
• 리프트 TIG: Uses a tungsten electrode. The arc is initiated by touching the tungsten electrode to the metal and then lifting it. This method minimizes tungsten contamination and offers better control compared to scratch-start TIG welding. It is perfect for precision welding of thin materials like stainless steel and other metals (excluding aluminum), producing high-quality, clean welds.

7. 유지관리

Warning: All maintenance, service, and cleaning work must be performed with the power removed. Make sure you have unplugged the power cord before opening the casing.

7.1 Safety Points for Maintenance

The welding machine is equipped with overcurrent and overheat protection circuits. If the grid voltage, output current, or internal temperature exceeds the set standard, the machine will automatically stop. However, excessive use (e.g., excessive voltage) can still damage the machine. Pay attention to the following:

• 좋은 환기: Ensure the ventilation area is not covered or blocked, and maintain a distance of at least 0.3 meters from surrounding objects. Good ventilation is crucial for the machine's performance and service life.
• 과부하를 피하십시오: Do not exceed the allowable load duration (refer to the nameplate parameters). Overloading significantly shortens the welder's life and can cause burns. The load continuation rate is the current welding time within a 10-minute cycle (working time + rest time = 10 minutes). For example, 30% duty cycle at 200A/28V means 3 minutes of work followed by 7 minutes of rest.
• Forbidden Voltage 너무 높음: 전원 공급 장치 볼륨tage must be within the specified range (refer to technical parameters). While the machine has an automatic voltage compensation circuit, exceeding the allowable voltag그러면 손상될 거예요.
• No Pipe Thawing: 파이프 해동을 위해 용접기를 사용하는 것은 금지되어 있습니다.
• 적절한 접지: The back of each welding machine has a grounding screw. Before use, connect a cable with a cross-section greater than 2.5mm² to reliably ground the machine casing, preventing static electricity or electrical leakage accidents.
• 과부하 보호: If the machine enters a protection state due to exceeding the standard load duration or high temperature, the yellow indicator light on the front panel will illuminate. Do not unplug the power supply; allow the cooling fan to continue operating until the light turns off and the temperature returns to normal.

7.2 정기 유지 관리

• Dedust Regularly: Use dry, clean compressed air to clean the system. In smoky or severely polluted environments, dedust daily. Ensure compressed air is delivered at the required pressure to avoid damaging internal components.
• Check Internal Contacts: Inspect internal contact areas, especially plug-in joints and components, to ensure tight connections. Reinforce any loose contacts. If rust or oxidation occurs, use sandpaper to remove the oxide film before reconnecting.
• 습기를 피하세요: Prevent water and moisture penetration. If this occurs, dry the inside of the welder and perform a megger insulation test (insulation between connection joints, and between joints and casing). Welding can only resume if no errors are detected.
• 저장: If the welder is not used for a long period, seal it in its original packaging and store it in a dry condition.

7.3 Before Maintenance Warning

Blind experiments and imprudent overhauls can lead to increased failures and difficulties in proper maintenance. Electronic equipment with exposed live parts can be dangerous. Any direct or indirect contact can cause electric shocks, potentially leading to death!
