Product Introduction
| Electrode Diameter (mm) | Welding Position | Current Range (A) | Voltage Range (V) | Welding Speed (mm/min) | Deposition Rate (kg/h) | Recommended Polarity | Core Operational Points |
|---|---|---|---|---|---|---|---|
| 2.5 | Flat Welding (1G) | 60-90 | 23-25 | 100-140 | 0.6-0.8 | AC/DCEN (DC Electrode Negative) | Higher current increases penetration, suitable for slightly thicker plates (1.5-3mm); lower current suits thin plates (0.5-1.5mm) to reduce burn-through. |
| 2.5 | Vertical (3G)/Overhead (4G) | 60-80 | 23-24 | 80-120 | 0.5-0.7 | AC/DCEN | Use short arc operation (arc length 1-2mm). For vertical welding, maintain 60-70° angle between electrode and base metal; for overhead welding, keep arc stable to prevent molten pool sagging. |
| 3.2 | Flat Welding (1G) | 90-130 | 24-26 | 120-160 | 0.9-1.2 | AC/DCEN | Suitable for 3-5mm plates. Optimal weld formation at 110-120A, with spatter rate controllable below 3%. |
| 3.2 | Vertical (3G)/Overhead (4G) | 80-100 | 23-25 | 100-140 | 0.8-1.0 | AC/DCEN | Use zigzag electrode manipulation for vertical welding, with swing amplitude not exceeding 3x electrode diameter; reduce swing and move quickly for overhead welding. |
| 4.0 | Flat Welding (1G) | 150-200 | 24-26 | 140-180 | 1.3-1.5 | AC/DCEN (DCEN preferred) | Suitable for 5-8mm plates. Multi-pass welding recommended: 150-170A for root pass, 180-200A for filling passes. |
| 4.0 | Vertical (3G)/Overhead (4G) | 140-170 | 24-25 | 120-150 | 1.2-1.4 | DCEN (recommended)/AC | For vertical welding, current should not exceed 160A to avoid oversized molten pools; for overhead welding, increase arc voltage to 25V to enhance slag coverage protection. |
| 5.0 | Flat Welding (1G) | 200-250 | 25-27 | 160-200 | 1.8-2.2 | AC/DCEN | Only recommended for flat welding, used for 8-12mm thick plates. Preheating to 80-120°C required; interpass temperature controlled below 250°C. |
