注記： An electrode holder and TIG torch are not included and must be purchased separately for MMA and TIG Lift welding, respectively.
4. セットアップとインストール
Before beginning any setup, ensure the welder is switched off and disconnected from the main power supply.
4.1電源接続
- 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 溶接ケーブルの接続
図4: The Bester 190C Welder with the MIG torch and earth clamp properly connected to the front panel terminals, ready for operation.
- アースClamp: アース線を接続するamp cable to the appropriate terminal on the front panel. Attach the clamp ワークピースにしっかりと固定し、良好な電気的接触を確保します。
- MIG-MAG Torch: 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.
- ガス漏れを防ぐために、すべての接続がしっかりと締まっていることを確認してください。
- 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)
- ワイヤスプールコンパートメントを開きます。
- 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.
- 駆動ローラーのテンションアームを閉じ、張力を調整します。ワイヤーは滑ったり変形したりすることなくスムーズに送られます。
- 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. 操作手順
The Bester 190C offers three welding processes: MIG-MAG, MMA, and TIG Lift.
5.1 Process Selection
- 主電源スイッチを使用して溶接機の電源をオンにします。
- 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 パラメータ調整
- 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： 溶接電流を調整する（amp電極の種類と直径に応じて、電流値（電流範囲）が決まります。
- 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つの高度な機能
The Bester 190C includes features to enhance welding performance:
- アークフォース： Automatically adjusts the welding current to prevent the electrode from sticking during MMA welding, improving arc stability.
- ホットスタート： Provides an initial boost of current at the start of MMA welding to ensure easy arc ignition.
- アンチスティック: Reduces the current if the electrode sticks to the workpiece during MMA welding, making it easier to detach and preventing overheating.
6. メンテナンス
定期的なメンテナンスは、溶接機の寿命を延ばし、最適な性能を維持するのに役立ちます。メンテナンスを行う前に、必ず溶接機の電源プラグを抜いてください。
- クリーニング： 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.
- ケーブル検査: Regularly inspect all welding cables, power cords, and gas hoses for cuts, abrasions, or damage. Replace damaged components immediately.
- トーチのメンテナンス: 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.
