1. はじめに
This manual provides essential information for the safe and effective use of ESAB OK 43.33 Rutile Electrodes. These electrodes are designed for welding common steels and general fabrication, offering stable arc characteristics and good weldability in all positions. Please read this manual thoroughly before use to ensure proper operation and safety.
2. 安全に関する注意事項
警告：溶接作業は危険を伴います。怪我や死亡事故を防ぐため、必ず安全上の注意事項を守ってください。
- 目と顔の保護: アーク光線や火花から目や顔を保護するために、必ず適切な遮光フィルター付きの溶接用ヘルメットを着用してください。
- 呼吸器の保護: Ensure adequate ventilation or use a respirator to protect against welding fumes and gases.
- 防護服: 火傷や感電を防ぐために、耐火性の衣服、手袋、安全靴を着用してください。
- 電気安全: Ensure welding equipment is properly grounded. Do not touch live electrical parts. Inspect cables for damage before use.
- 防火： 溶接エリアから可燃物を遠ざけてください。消火器をすぐに使えるようにしておいてください。
- 作業エリア: Keep the work area clean, dry, and free of obstructions.
- 応急処置： Know basic first aid procedures for burns and electric shock.
3. セットアップ
- 溶接機器の準備: Connect the welding machine according to the manufacturer's instructions. Ensure all cables (electrode holder cable, ground cable) are securely attached and in good condition.
- グラウンドClamp: 地面を取り付けるclamp firmly to the workpiece or a clean, bare metal surface close to the weld area to ensure a good electrical connection.
- 電極の選択: Select the appropriate ESAB OK 43.33 electrode diameter (2.5 mm) for your application and welding current.
- ワークピースの準備: Clean the welding area of any rust, paint, oil, or other contaminants that could affect weld quality. Bevel thick sections if necessary.
- 換気： Ensure proper ventilation in the welding area to disperse fumes.
4. 操作手順
- 現在の設定： Set the welding current on your machine according to the electrode manufacturer's recommendations for the 2.5 mm diameter. Typical current ranges are provided on the electrode packaging.
- Arc Striking: Strike the arc by lightly scratching the electrode tip against the workpiece, similar to striking a match. Once the arc is established, lift the electrode slightly to maintain a short arc length.
- 電極角度: Maintain an electrode angle of approximately 70-80 degrees to the workpiece in the direction of travel.
- 移動速度： Maintain a consistent travel speed to ensure uniform bead width and penetration. Too fast a speed results in a narrow, convex bead; too slow a speed can lead to excessive heat input and a wide, flat bead.
- Welding Positions: ESAB OK 43.33 electrodes are suitable for welding in all positions (flat, horizontal, vertical up/down, overhead). Adjust technique and current slightly for different positions as needed.
- スラグ除去: After completing a weld pass, allow the weld to cool slightly, then remove the slag using a chipping hammer and wire brush.
5. メンテナンス
- 電極の保管： Store ESAB OK 43.33 electrodes in a dry environment, preferably in their original sealed packaging, to prevent moisture absorption. Moisture can lead to porosity in welds.
- 設備検査: Regularly inspect your welding machine, cables, and electrode holder for wear or damage. Replace any damaged components immediately.
- クリーニング： Keep welding equipment clean and free of dust and debris.
6。 トラブルシューティング
| 問題 | 考えられる原因 | 解決 |
|---|---|---|
| Poor Arc Striking | Low current, damp electrode, poor ground connection | Increase current, dry electrodes, ensure good ground connection |
| 溶接部の気孔 | Damp electrodes, insufficient shielding, contaminated workpiece | Dry electrodes, check arc length, clean workpiece thoroughly |
| 過度のスパッタ | Too high current, long arc length | Reduce current, maintain short arc length |
| Lack of Penetration | Too low current, too fast travel speed | Increase current, reduce travel speed |
| アンダーカット | Too high current, incorrect electrode angle, too fast travel speed | Reduce current, adjust angle, slow down travel speed |
