Troubleshooting Guide
- Machine Not Powering On: Check power source (380V), fuses, and internal connections.
- Electrode Sticking: Increase current, ensure good ground, and use dry rods.
- Excessive Spatter: Reduce amperage, verify correct polarity, and maintain short arc length.
- Poor Penetration: Increase current, reduce speed, or use correct electrode type.
- Overheating: Let the unit cool, clean vents, and respect duty cycle limits.
- Arc Cutting Out: Tighten all cable connections and inspect holder and internals.
Recommended Stick Welding Settings
| Electrode Type | Electrode Size | Amperage Range | Polarity | Application Notes |
|---|---|---|---|---|
| E6013 | 2.5 mm | 70 – 100 A | DCEP | Light fabrication, thin steel |
| E6013 | 3.2 mm | 100 – 130 A | DCEP | General steel welding |
| E6013 | 4.0 mm | 140 – 180 A | DCEP | Medium-thickness sections |
| E6013 | 5.0 mm | 180 – 220 A | DCEP | Thicker plate work |
| E7018 | 3.2 mm | 110 – 140 A | DCEP | Structural, pressure vessels |
| E7018 | 4.0 mm | 150 – 190 A | DCEP | Heavy structural steel |
| E7018 | 5.0 mm | 190 – 240 A | DCEP | High-strength applications |

Quick Welding Tips
- Keep arc length equal to rod diameter for best control.
- DCEP is standard for general-purpose rods (6013, 7018).
- Use lower amps and smaller rods for thin metals.
- Bevel thick steel and use multi-pass with 4.0 or 5.0 mm rods.
- Store electrodes in dry conditions to prevent moisture damage.
FAQs
Which welder is best for beginners?
Stick (ARC) welders like the EWELDS315 are suitable for beginners due to their simplicity, portability, and affordability.
Why does my electrode stick?
This can happen due to low amperage, poor grounding, or using damp electrodes. Increase current and ensure clean, dry materials.
What causes weld spatter?
Excessive amperage or incorrect polarity can lead to more spatter. Adjust current and ensure correct settings for electrode type.
What size welding cable should I use?
For high current machines like the EWELDS315, use heavy-duty welding cables (at least 25mm² or larger depending on length).
What safety precautions should I take when welding?
Always wear a welding helmet, gloves, long sleeves, and ensure proper ventilation. Disconnect power before maintenance.
