Quick Answer
Check the current range for the exact 2.5 mm E6013 product, not the classification alone. ESAB Weld 6013 lists 50–90 A for its 2.5 mm rod, while ESAB LBL BW E6013 lists 70–90 A. Match the product, polarity and machine to the joint and any controlling welding procedure. Validate a starting setting on a representative test weld.
Key Takeaways
- Two published 2.5 mm E6013 products list different current ranges.
- A 3/32-inch (nominal 2.4 mm) product is not automatically the same SKU as a 2.5 mm rod.
- A manufacturer’s range does not replace an applicable welding procedure or joint trial.
What Do 2.5 mm Product Sheets Say?
ESAB Weld 6013 publishes 50–90 A for its 2.5 × 350 mm product. Its page lists AC and DC+ and a minimum AC open-circuit voltage of 50 V.
ESAB LBL BW E6013 publishes 70–90 A for a separate 2.5 × 350 mm item. Do not average the ranges or treat their overlap as a universal E6013 rule.
For comparison only, Lincoln Fleetweld 37 lists a nominal 2.4 mm (3/32-inch) row with 75–115 A on AC and 70–105 A on DC. That 2.4 mm row must not be relabeled as a 2.5 mm product.
| Named product | Published size and range | Buyer check |
|---|---|---|
| ESAB Weld 6013 | 2.5 × 350 mm; 50–90 A | Confirm AC/DC+ and machine OCV. |
| ESAB LBL BW E6013 | 2.5 × 350 mm; 70–90 A | Verify sheet revision and offered SKU. |
| Lincoln Fleetweld 37 | 2.4 mm; AC 75–115 A, DC 70–105 A | Keep 2.4 mm separate from 2.5 mm. |
Why Can One Nominal Size Need Different Settings?
AWS A5.1/A5.1M classifies covered carbon-steel SMAW electrodes; E6013 does not define one manufacturer’s current schedule. Product construction, polarity, position and joint geometry matter.
For an AC welder, check the proposed rod’s minimum open-circuit voltage as well as its current range. Check actual machine output, leads and permitted travel direction rather than relying only on the amperage dial.
Thin or poorly fitted material can burn through even within a published range; low current can also give sticking or poor fusion. Neither observation authorizes a setting outside the approved procedure.
How Should Buyers Validate a Starting Setting?
Start with the current datasheet for the exact trade name, nominal diameter and length. If the job is governed by a welding procedure specification (WPS), use only settings that it permits.
On representative base metal, joint and position, record the actual machine, polarity, welder, product lot and trial current. Evaluate arc stability, fusion, slag, bead appearance and distortion using the project’s acceptance method.
If a sample fails, inspect fit-up, surface preparation, travel and equipment output before changing the current alone. A good practice bead is not formal procedure qualification.
What Should the RFQ Specify?
RFQ checklist:
- Manufacturer, trade name and SKU: identify which published current row applies.
- E6013 class and nominal 2.5 mm core size: prevent substitution with a 2.4 mm item.
- Rod length and net pack weight: compare identical saleable units.
- Polarity and current range by size: match machine and planned position.
- AC open-circuit-voltage guidance where relevant: screen start-up compatibility.
- Dated datasheet, lot label and sample: tie printed instructions to the delivered product.
Ask the supplier to reconcile any conflicting document revisions before approving a carton label.
Buyer FAQ
Is 70–90 A the universal range for 2.5 mm E6013?
No. A different named 2.5 mm product publishes 50–90 A; use the applicable product sheet and procedure.
Can a 2.4 mm table be used for 2.5 mm rods?
No. Treat those as separate nominal product sizes unless the manufacturer explicitly documents the offered item.
Should every joint use the top of the maker’s range?
No. Select and validate a permitted starting setting for the actual joint and position.
