WY20 · batch-marked tip
WY20 Yttriated Tungsten Electrode (approx. 2% Y2O3)
Yttria-doped electrodes hold a tight, concentrated arc at high DC current with low tip erosion — the choice for precision and critical-joint work where arc wander is not acceptable.
WY20 is a made-to-order line for us: we confirm diameter, length, tip marking and date before you commit, so your procedure documentation matches what arrives.

Tip colour per ISO 6848.

Where WY20 earns its place
Critical DC joints
Thin-wall tube, aerospace-adjacent assemblies, automated heads with tight arc-length windows: yttria’s stable emission keeps the arc where the program puts it.
High-current endurance
Where WL20 tips would need frequent re-dressing, WY20 holds geometry longer at equal amperage.
Ordering honestly
Because it is made to order, we quote WY20 with an explicit production date and marking scheme. No phantom stock, no substitution surprises.
Alternatives to compare
If your current range is medium rather than extreme, WL20 often covers the job from stock — ask and we will say so plainly.
Real stock, photographed as shipped
No studio renders. These are the tube boxes, labels and cartons that leave our Baoji packing room — the same ones your incoming inspection will open.
