Frequently asked questions
What makes WY20 different from lanthanated?
Yttrium oxide gives an especially concentrated arc and strong tip stability at high temperatures. It is chosen for demanding, high-value work rather than everyday general fabrication.
Which polarity does WY20 use?
DCEN mainly. For AC applications, WP, WL20 or WZ8 are normally better suited.
Can you supply certificates with WY20?
Yes — certified analysis and export documents are provided on request with each shipment. Ask Tockson when you request a quote.
