Oferta
HYW ER70S-2 TIG Welding Rod — 5 lb is a premium triple-deoxidized solid carbon-steel filler rod in 36-inch cut lengths, supplied in a 5 lb tube. Containing zirconium, titanium, and aluminum deoxidizers, it produces exceptionally clean, porosity-free welds even over rust and mill scale — the preferred filler for high-quality root passes on pipe and out-of-position GTAW.
Key Features
- › Triple-deoxidized (Zr, Ti, Al) for superior, porosity-free welds
- › Excellent over rust, mill scale, and less-than-clean base metal
- › Premium choice for X-ray quality pipe root passes
- › Bright, controllable puddle for precise out-of-position welds
- › Copper-coated, straightened 36" rods supplied in a 5 lb tube
Ideal Applications
- › Pipe and tube root passes (X-ray quality)
- › Pressure vessels and code-governed fabrication
- › Out-of-position GTAW on carbon and low-alloy steel
- › Boiler, refinery, and power-generation work
- › General precision mild-steel TIG welding

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.
