E308L-16 Stainless Steel Rod: Amperage, Settings & 304 Welding Guide
The standard stainless steel stick rod. Runs 30 to 160 amps on AC or DCEP, rated for flat, horizontal, vertical up, overhead. Amperage chart by diameter below.
E308L-16 is the go-to stick electrode for welding 304 and 304L austenitic stainless steel. The L designates low carbon content (0.04% max), which prevents carbide precipitation in the heat-affected zone and maintains corrosion resistance. The -16 suffix means it runs on AC or DCEP with a smooth, quiet arc. Slag is heavy and self-peeling. Bead appearance is excellent with fine ripples. This is the rod you reach for on food service equipment, chemical tanks, pharmaceutical piping, and any 304 stainless fabrication.
What This Means in Practice
E308L-16 means: E (electrode) + 308 (308 stainless filler chemistry) + L (low carbon, 0.04% max) + 16 (rutile coating, AC or DCEP). The 308 chemistry matches 304 base metal because the filler is intentionally slightly over-alloyed.

Amperage by Individual Diameter
3/32 E308L-16 Amperage
Set 3/32 E308L-16 to 30 - 60 amps. Run AC or DCEP. This is the smallest available size. Best for vertical-up and overhead where you need a small, controllable puddle. Start around 45A.
1/8 E308L-16 Amperage
Set 1/8 E308L-16 to 50 - 90 amps. Run AC or DCEP. This is the most commonly used E308L-16 size. Start at 70A for flat work, drop to 50-63A for vertical-up.
5/32 E308L-16 Amperage
Set 5/32 E308L-16 to 75 - 120 amps. Run AC or DCEP. High fill rate in flat position. Drop 10-15A if you see undercut at the toes.
3/16 E308L-16 Amperage
Set 3/16 E308L-16 to 100 - 160 amps. Run AC or DCEP. Largest available diameter. High deposition for flat and horizontal fillet welds on thick plate. Requires 100A minimum to run properly.
E308L-16 Suitability Scores
How well this electrode matches common applications. Not a quality rating. all AWS-certified electrodes meet their specification.
What Is E308L-16 Good For?
304 and 304L stainless steel fabrication and repair.
Food processing equipment, kitchen equipment, pharmaceutical tanks, dairy piping.
Any application requiring matching stainless filler with corrosion resistance equivalent to the base metal.
Where E308L-16 Falls Short
Only for 304/304L stainless, do not use on 316 (use E316L) or on dissimilar metals (use E309L).
Must run at lower amperages than carbon steel rods to prevent overheating and warping.
Stainless does not dissipate heat quickly, so interpass temperature control matters.
Higher cost per pound than carbon steel consumables.
E308L-16 Under the Hood
The Arc
Smooth, stable arc with a medium crackle. The rutile-based coating produces a consistent arc that is forgiving of arc length variations. Easier to run than most stainless rods.
Technique
Drag at 10-15 degrees. Move faster than you would with carbon steel rods. Stainless holds heat longer, so faster travel prevents overheating and distortion. Keep interpass temperature below 350F.
The Puddle
Bright, fluid puddle that looks distinctly different from carbon steel. The molten stainless has a glassy appearance. The slag is thin and light, peeling off easily. The bead has a characteristic golden to straw color when properly shielded.
When It Goes Wrong
If the bead turns gray or black instead of golden/straw color, your arc is too long and atmospheric contamination is reaching the puddle. Shorten up. If the bead discolors to dark blue or purple, you are overheating the joint. Move faster or let it cool.
Which Size E308L-16 to Use
| Rod Diameter | Material Thickness | Application |
|---|---|---|
| 3/32" | 1/16" to 1/8" | Thin stainless sheet and tubing |
| 1/8" | 1/8" to 1/4" | Standard stainless fabrication |
| 5/32" | 1/4" and up | Heavier stainless plate |
What the Spec Sheet Leaves Out
E308L-16 is the stainless rod you reach for on 304 and 304L stainless steel. The L means low carbon, which prevents sensitization (chromium carbide precipitation) in the heat-affected zone. Sensitization leads to intergranular corrosion, which eats stainless from the inside out. On food-grade, pharmaceutical, or chemical processing equipment, E308L-16 is not optional. It is the minimum requirement.
Bottom Line
This rod was made for structural work. E316L-16 covers what E308L-16 cannot.
Setup & Safety Reference
How to Store E308L-16
Stainless rutile (-16) electrode. Keep sealed and dry.
Max Atmosphere Exposure: 8 hours before reconditioning
Reconditioning Temperature: 300-350°F for 1-2 hours
Stainless rutile (-16) electrode. Keep sealed and dry. If exposed to moisture, bake at 300-350F for 1-2 hours. Less moisture-sensitive than low-hydrogen rods but still benefits from dry storage.
Preheat & Interpass Temperature for E308L-16
Preheat is generally not required for austenitic stainless steel. Excessive preheat can cause sensitization and reduce corrosion resistance.
| Base Metal Thickness | Minimum Preheat (°F) |
|---|---|
| all thicknesses | Not required |
Maximum interpass temperature: 350°F

E308L-16 Questions
What base metal does E308L-16 match?
E308L-16 matches 304 and 304L austenitic stainless steel. The L designation means low carbon (0.03% max), which reduces carbide precipitation and intergranular corrosion in the heat-affected zone.
Can E308L-16 be used on carbon steel?
No. For joining stainless to carbon steel (dissimilar metals), use E309L-16 instead. E308L-16 is only for stainless-to-stainless joints.
What polarity for E308L-16?
E308L-16 runs on AC or DCEP. DCEP gives better arc stability and penetration. AC works when DC is not available.
