E6011 cellulose AC/DC rod for field work vs E6012 titania rod for production flat welding.
Which One Should You Use?
Pick E6012 if:
Runs on AC, DCEN, 40-350A range. E6012 full amperage chart
Key Differences
| Attribute | E6011 | E6012 |
|---|---|---|
| Penetration | Deep, aggressive | Light, shallow |
| Deposition Rate | Lower | Higher - heavy titania coating |
| Dirty Metal | Excellent | Poor - clean metal only |
| Positions | All positions | Flat and horizontal preferred |
| Arc Character | Forceful, digging | Soft, quiet |
| Flux Type | Cellulose potassium | Rutile sodium |
| Slag | Thin, papery | Heavier, fills freeze pattern |
| Polarity | AC, DCEP | AC, DCEN, DCEP |

| Setting | E6011 | E6012 |
|---|---|---|
| Polarity | AC, DCEP | AC, DCEN |
| Positions | flat, horizontal, vertical-up, vertical-down, overhead | flat, horizontal, vertical-up, overhead |
| Penetration | deep | medium |
| Coating | high cellulose potassium | high titania sodium |
| Amps at 3/32" | 40-85A | 40-90A |
| Amps at 1/8" | 75-130A | 80-140A |
| Amps at 5/32" | 100-180A | 110-190A |
How E6011 and E6012 Work Together
E6011 is the general-purpose repair rod that handles all positions and dirty metal. E6012 is the production rod for flat and horizontal position where deposition rate matters. E6012 fills joints faster thanks to its heavy titania coating, but it has much less penetration and cannot handle contaminated surfaces. Think of E6011 as the versatile field rod and E6012 as the shop production rod.
Common Mistake With Deep Penetration AC/DC
Using E6012 for repair work on rusty equipment. E6012 needs clean metal to produce sound welds. Its fill-freeze arc does not burn through contamination. For dirty metal, use E6011 or E6010.
Practical Differences
| Factor | E6011 | E6012 |
|---|---|---|
| Fume Level | High (0.8-1.5 g/min) | Medium (0.4-0.8 g/min) |
| Common Brands | Fleetweld 35LS, Hobart 335A | Fleetweld 7, Hobart 12A |

E6011 vs E6012: Common Questions
Which is better, E6011 or E6012?
Wrong question. They solve different problems. Key differences: Penetration: E6011 has deep, aggressive, while E6012 has light, shallow. Deposition Rate: E6011 has lower, while E6012 has higher - heavy titania coating. Dirty Metal: E6011 has excellent, while E6012 has poor - clean metal only. The comparison table on this page breaks down each trade-off.
Can I substitute E6011 for E6012?
Only if the specs allow it. E6011 runs on AC/DCEP, E6012 on AC/DCEN. Your machine decides. Penetration differs: E6011 is deep, E6012 is medium. Coating chemistry is different (high cellulose potassium vs high titania sodium), so the arc and slag behave differently.
Can I use both E6011 and E6012 on the same joint?
E6011 is the general-purpose repair rod that handles all positions and dirty metal. E6012 is the production rod for flat and horizontal position where deposition rate matters. E6012 fills joints faster thanks to its heavy titania coating, but it has much less penetration and cannot handle contaminated surfaces. Think of E6011 as the versatile field rod and E6012 as the shop production rod.
