Available Sizes & Recommended Amperage
| Diameter | Recommended Amperage |
|---|---|
| 1/16" (1.6 mm) × 36" | 70 – 110 A |
| 3/32" (2.4 mm) × 36" | 100 – 160 A |
| 1/8" (3.2 mm) × 36" | 120 – 210 A |
Recommended amperage ranges are general guidelines; optimal settings vary with base-metal thickness, joint design, tungsten selection, and welding position. Store filler rod in a dry location to prevent oxidation and ensure clean welds.
