The CK T3327GC2 ceriated tungsten is a 2% ceriated, gray-tip TIG electrode in the 3/32 inch by 7 inch size. Retailer pages list it for both AC and DC welding and recommend it for low-amperage and precision work on steel, stainless steel, nickel alloys and titanium. It is a good non-radioactive general-purpose pick for thin material and easy starts, but it is not the usual choice for high-amperage DC work.

What Ceriated Tungsten Is Good For
Ceria is added to the tungsten to make arcs start easily and stay steady at low current. That makes ceriated electrodes a common choice for thin sheet, small parts and precision work. They are not radioactive, unlike thoriated electrodes.
Ceriated is often used on DC, and many welders also run it on AC for light work. For heavy-duty AC aluminum or high-amperage jobs, other electrode types may suit better.
Which CK 3/32 Electrode Should You Pick?
CK sells the same 3/32 x 7 inch size in several compositions. Use this table to compare them, then read each review.
| Part | Type | Typical use |
|---|---|---|
| T3327GC2 | 2% ceriated (gray) | Low-amp starts, thin material, AC and DC |
| T3327GL2 | 2% lanthanated (blue) | Non-radioactive all-rounder, AC and DC |
| T3327GT2 | 2% thoriated (red) | Mostly DC; contains thorium |
| T3327GTM | LaYZr rare earth (chartreuse) | All-purpose, AC and DC |
How to Check It Fits Your Setup
- Collet size: you need a 3/32 inch collet and collet body or gas lens.
- Length: 7 inch electrodes suit standard torches; check that the length works with your back cap.
- Amperage: check the manufacturer’s current chart for 3/32 inch tungsten and match it to your machine and process.
- Pack quantity: confirm how many electrodes are in the pack before comparing prices.
- Grinding: a dedicated tungsten grinder, such as the one in our SONNLER tungsten sharpener review, keeps the taper consistent.
Pros and Limitations
Pros
- Non-radioactive 2% ceriated composition
- Suited to easy starts at low amperage
- Works on AC and DC per retailer pages
- Pre-ground tip is ready to use
Limitations
- Not usually chosen for high-amperage DC work
- Pack size and price vary between sellers
- You still need to regrind the tip as it wears
Using Tungsten Safely
- Grind with dust extraction or in a ventilated space, and wear eye protection.
- Grind so the marks run along the length of the electrode.
- Store electrodes in a tube so the tips are not chipped.
- Keep the electrode clean, and regrind if it is contaminated by touching the work or filler.
Frequently Asked Questions
What is the CK T3327GC2?
It is a 2% ceriated, gray-tip TIG tungsten electrode in the 3/32 inch by 7 inch size, according to retailer product pages.
Is ceriated tungsten radioactive?
No. Ceriated tungsten is a non-radioactive alternative to thoriated tungsten. You should still use dust control when grinding any tungsten.
Can I use it for AC and DC?
Retailer pages list it for both AC and DC TIG welding. Many welders prefer other electrode types for heavy AC aluminum work, so check your machine settings and the manufacturer’s guidance.
How does it differ from lanthanated and LaYZr tungsten?
All are non-radioactive options. Ceriated is known for easy starts at low amperage, while the lanthanated T3327GL2 and the LaYZr T3327GTM are positioned as broader all-rounders.
Final Thoughts
The CK T3327GC2 is a straightforward 2% ceriated electrode for low-amp and precision TIG work. Confirm the pack quantity, then choose the composition that matches your metals and current.
