TIG Tungstens - RE4 (Rare-Earth) AC/DC
The high-performance, All-metal tungsten! Weldclass RE4 purple-tip TIG Tungsten electrodes are suitable for both DC (Steel, Stainless steel etc) and AC (Aluminium) TIG welding. Maintains tip shape, reliable arc striking, low burn off rate, long service life and smooth/stable arc.
Also Known As:
Rare-Earth Style TIG & GTAW Welding Tungsten Electrodes, replaces Thoriated, Zirconiated, Witstar, Lanthanated and other electrodes
WC-05192 79.08
KEY FEATURES
- Universal: "All metal" Tungsten Suitable for DC (Steel, Stainless steel etc) and AC (Aluminium)
- Convenient: Replaces virtually all other types of Tungstens, including; Thoriated (red tip) & Zironiated (white tip)
- Safe: Unlike Thoriated (red tip) tungstens, does Not contain radioactive elements = No special safeguards required for use, storage or transport
- High Performance: Maintains tip geometry, reliable arc striking, low burn off rate, long service life and smooth/stable arc
APPLICATION INFO:
- DC welding of mild steel, stainless steel, copper and chrome molly
- AC TIG welding of: Aluminum alloys and Aluminum bronze
WHAT ELSE?
- A Hazard-Free (non-radioactive) Replacement for Thoriated electrodes
- Also replaces Zirconiated, Lanthanated and other electrodes
- Purple (Turquoise) Colored Tip
- Contains additives/combinations of "rare-earth" oxides, scientifically balanced to provide optimum arc characteristics and wear life
- Compared to other tungsten formulas: Requires less energy to start, Runs cooler, Longer Electrode Life, Greater current capacity (ability to use a smaller-diameter electrode for the same job or use higher current for a similar-sized electrode)
Material Thickness vs Amps vs Tungsten Size
Because of the many variables in any given TIG welding application, there is no single formula to say "for X thickness you need X amps".
The many factors that influence this include; material being welded, type of tungsten elecrode used, type of weld joint, weld position, operator technique, skill and/or experience, required strength or quality of the weld joint, etc.
However, here is a rough guide for TIG welding of steel, stainless or aluminium:
| Material Thickness* | Suggested Tungsten Size* | Amps Required* |
| <1mm | 1.0mm | 10-30A |
| <2mm | 1.6mm | 30-80A |
| 2-3mm | 2.4mm | 80-150A |
| 4-5mm | 3.2mm | 150-200A |
*This is a general guide only and should not be used as specific advice for any particular application

Not sure if it's me or these rods but I seem to be able to weld better with these rods and the tip seems to stay intact. I mainly weld aluminium and have also tried other brands with Ceriated / lanthanated / zirconiated but having differing quality/tip problems.
