Why choose WL20 from Midwest Tungsten Service — 2% lanthanated, 3/32″ rods, 10-pack and reliable arc starts
What are the benefits? Improved tungsten properties give stable arc control, low electrode erosion, and suitability for AC and DC use.
How long will they last? Electrode longevity depends on current, duty cycle, and technique; typical users report extended service versus pure thoriated types.
Practical considerations: choose correct grind, match amperage to 3/32″ (approx. 100–150 A peak), store dry, and replace when tip deforms to maintain weld quality.
Materials and Welding Applications
Building on the practical advice for WL20 usage and life expectancy, the materials and welding applications for 2% lanthanated (WL20/EWLa-2) 3/32″ electrodes are broad and predictable: these electrodes perform well on aluminum and magnesium alloys in AC, and on steels, stainless steels, copper, nickel, titanium, and their alloys in DC or mixed-polarity setups.
What materials suit WL20?
- Aluminum, magnesium: AC, clean oxide control.
- Steels, stainless: DC-, 3/32″ fits 80–200 A ranges.
- Copper, nickel, titanium: DC or mixed.
How to adapt welding techniques?
– Use 2–4 mm stickout, steady gas flow, appropriate amperage, and proper torch angle.
Tungsten properties enable stable arcs, low contamination, extended life.
Performance in AC and DC TIG Welding
Performance in AC and DC TIG welding for 2% lanthanated (WL20/EWLa-2) 3/32″ electrodes is characterized by stable arc initiation, low erosion rates, and broad amperage flexibility, making them a versatile choice across many applications. The reviewer notes clear AC performance benefits on aluminum, consistent arc tracking at 60–150 A, and dependable DC performance on steels and alloys, with minimal balling at 10–200 A. Practical considerations: tip grind, torch angle, and gas flow.
| Metal | Typical Amps | Observed Behavior |
|---|---|---|
| Al | 60–150 A | Clean, stable arc |
| Steel | 10–200 A | Tight bead control |
| Ni | 20–180 A | Low erosion rate |

Frequently Asked Questions
What Grit or Tip Shape Do the Electrodes Arrive With?
They arrive as pre-cut WL20 electrodes with a pointed tip suitable for general TIG work; electrode types include 2% lanthanated rods, and tip preparation typically requires light grinding to achieve desired fine point or truncated shape.
Can These Electrodes Be Reground for Pointed Tips?
Straightaway: yes — as a rule of thumb, they can be reground to pointed tips. Following proper regrinding techniques preserves electrode longevity; care, correct angles, and gentle cooling keep performance consistent and extend usable life.
Are These Electrodes Compatible With Plasma Cutting Torches?
No — they are not compatible with plasma cutting torches. The responder notes compatibility concerns: TIG tungsten is designed for torch performance in TIG systems, not plasma cutting, and using it in plasma torches can impair performance and safety.
Do They Come in Other Pack Sizes or Bulk Options?
Like a tool chest filled with choices, the company offers varied pack sizes and bulk options: single packs, 10-packs, larger multi-packs, and bulk quantities for professionals, accommodating different budgets and usage rates with reliable WL20 tungsten selections.
Is There a Recommended Storage Method to Prevent Contamination?
Yes. They recommend dry, sealed packaging and clean, low-humidity storage to prevent contamination; electrode storage in labeled, airtight containers or desiccant-lined cases keeps tips pristine, minimizing handling and exposure to oils, dust, and moisture for best performance.
Conclusion
Midwest Tungsten Service WL20 electrodes deliver reliable 2% lanthanated performance for 3/32″ TIG use, with stable arc starts, low erosion, and consistent results on aluminum and stainless steel. Are they worth it? Yes: packs of 10, made in the USA, batch certificates for traceability, and clear safety documentation. Practical tip: expect predictable life under typical AC/DC settings, but match amperage and grinding profile to application — a small change makes a big difference.
