Deep Penetration AC/DC vs Fill-Freeze Production Rod
E6011 cellulose AC/DC rod for field work vs E6012 iron-powder rod for production flat welding.
Key Differences
| Attribute | E6011 | E6012 |
|---|---|---|
| Penetration | Deep, aggressive | Light, shallow |
| Deposition Rate | Lower | Higher - iron powder 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 |

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 iron powder 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.
