메모: An electrode holder and TIG torch are not included and must be purchased separately for MMA and TIG Lift welding, respectively.
4. 설정 및 설치
Before beginning any setup, ensure the welder is switched off and disconnected from the main power supply.
4.1 전원 연결
- Connect the welder to a 230V single-phase power supply. The machine is designed to operate within a voltage range of 230V +/- 15%.
- Ensure the power outlet is properly grounded and capable of supplying the required current (16A fuse recommended).
- The Bester 190C is compatible with sufficiently powerful generators.
4.2 용접 케이블 연결

- 지구 Clamp: 접지선을 연결하세요amp cable to the appropriate terminal on the front panel. Attach the clamp 공작물에 단단히 고정하여 양호한 전기 접촉을 보장합니다.
- MIG-MAG 토치: Connect the MIG-MAG torch to its designated connector on the front panel. Ensure it is firmly seated.
- MMA/TIG (Optional): If using MMA or TIG Lift, connect the electrode holder or TIG torch to the appropriate terminals (positive or negative, depending on polarity requirements for the specific process and electrode/filler material).
4.3 Gas Connection (for MIG-MAG and TIG)
- Connect the gas hose from your shielding gas cylinder (e.g., Argon/CO2 mix for MIG, pure Argon for TIG) to the gas inlet on the welder.
- 가스 누출을 방지하기 위해 모든 연결부가 단단히 조여져 있는지 확인하십시오.
- Set the gas flow rate according to your welding process and material requirements using a flowmeter on the gas cylinder regulator.
4.4 Wire Loading (for MIG-MAG)
- 와이어 스풀 보관함을 엽니다.
- Place the wire spool (max 5 kg, 200 mm diameter) onto the spindle, ensuring it rotates freely.
- Feed the welding wire through the guide tube and into the drive rollers.
- Close the drive roller tension arm and adjust the tension. The wire should feed smoothly without slipping or deforming.
- With the torch pointed away from yourself and others, press the trigger to feed the wire through the torch liner until it exits the contact tip.
- The welder supports wire diameters from 0.6 mm to 1.0 mm.
5. 사용 설명서
The Bester 190C offers three welding processes: MIG-MAG, MMA, and TIG Lift.
5.1 공정 선택
- 용접기의 전원 스위치를 켜십시오.
- Use the mode selection buttons on the front panel to choose your desired welding process: MIG-MAG, MMA, or TIG Lift. The selected mode will be indicated on the digital display.
5.2 매개변수 조정
- MIG-MAG: Adjust the welding current (wire feed speed) and voltage using the dedicated knobs. Refer to welding charts for recommended settings based on material thickness and wire type. The machine allows for easy polarity inversion.
- MMA : 용접 전류를 조정하십시오.amperage) based on the electrode type and diameter.
- TIG Lift: Adjust the welding current. TIG Lift arc starting requires touching the tungsten electrode to the workpiece and then lifting it slightly to initiate the arc.
5.3 고급 기능
The Bester 190C includes features to enhance welding performance:
- 아크 포스: Automatically adjusts the welding current to prevent the electrode from sticking during MMA welding, improving arc stability.
- 핫 스타트 : Provides an initial boost of current at the start of MMA welding to ensure easy arc ignition.
- 안티-스틱: Reduces the current if the electrode sticks to the workpiece during MMA welding, making it easier to detach and preventing overheating.
6. 유지관리
정기적인 유지보수는 용접기의 수명 연장과 최적의 성능을 보장합니다. 유지보수를 수행하기 전에는 항상 용접기의 전원을 차단하십시오.
- 청소: Periodically clean the exterior of the machine with a dry, soft cloth. Use compressed air to blow out dust from inside the machine, especially around cooling vents, but ensure the air is dry and oil-free.
- 케이블 검사: Regularly inspect all welding cables, power cords, and gas hoses for cuts, abrasions, or damage. Replace damaged components immediately.
- 토치 유지보수: For MIG-MAG, regularly clean the contact tip, gas nozzle, and check the wire liner for blockages or wear. Replace consumables as needed. For TIG, inspect the tungsten electrode and sharpen or replace as necessary.
- Drive Rollers (MIG-MAG): Clean the drive rollers and ensure they are free of wire debris. Check for proper tension.
