Stick electrode current is selected from more than the AWS class. Diameter, coating, manufacturer, polarity, position and the electrode’s specific product formulation all matter. This table collects Lincoln Electric ranges for three named products classified in the E70 family: Fleetweld 47, IronArc 7018 MR and Jetweld 1. It is a starting reference for those products, not a universal setting chart for every E70XX electrode.

E70XX stick welding current ranges

Read the product and polarity columns together

Each row pairs one manufacturer product with its AWS classification, diameter, current type and minimum/maximum range. Fleetweld 47 is listed as E7014 and uses AC or DC electrode negative in its own data sheet; the rows here report the AC band in the selected manufacturer source. IronArc 7018 MR is listed as E7018 H4R with separate AC and DC-positive ranges, so both appear as distinct entries. Jetweld 1 is listed as E7024-1 and the table gives the AC range provided for its offered diameters.

Diameter is the nominal electrode diameter in millimetres. Current is amperes. A larger diameter commonly accepts a higher range, but do not interpolate between rows: the product manufacturer publishes ranges for specific sizes, and some sizes or polarities may not be available. If the electrode packaging, class suffix, product name or regional sheet differs, use the matching current product document.

Choosing a starting setting

First identify the exact electrode in the shop and confirm that it matches the approved welding procedure. Then choose the diameter and current type allowed for the weld position and joint. A setting within the published band is only a starting point; joint geometry, base metal thickness, fit-up, travel speed and machine characteristics influence the final setting. Follow the procedure’s qualified parameters when one applies. Do not raise current simply because an arc feels difficult to maintain until electrode condition, polarity, lead connections and technique have been checked.

Why E70XX is not one interchangeable range

The E70 prefix indicates a classification family, while the remaining digits and suffixes add requirements about position, coating, chemistry, diffusible hydrogen or other characteristics. A cellulosic electrode, an iron-powder electrode and a low-hydrogen electrode can behave differently even when their deposited weld metal strength class appears similar. Manufacturers also test and recommend current for particular formulations. That is why this reference keeps the product name and exact class visible instead of collapsing all values into one E70XX range.

For example, the IronArc E7018 H4R sheet gives AC bands of 80–120 A at 2.4 mm, 100–160 A at 3.2 mm and 130–220 A at 4.0 mm. The same product’s DC-positive ranges are 70–110, 90–160 and 120–220 A. Those paired numbers are not a license to substitute another E7018 brand or hydrogen suffix. Check the package and current product sheet before applying them.

Limits and safe use

Welding current recommendations do not define the complete welding procedure. Confirm the required process, base metal, preheat/interpass controls, joint preparation, position, travel direction, filler classification and acceptance criteria. Low-hydrogen electrodes may require controlled storage and handling; follow the product instructions and governing code. Use appropriate eye, skin, respiratory and electrical protection, and have a qualified welding professional approve settings where the work is safety-critical.

The listed bands are manufacturer data, not calculated values. Empty or unsupported size/polarity combinations are intentionally omitted. If the chosen product is not Fleetweld 47, IronArc 7018 MR or Jetweld 1, consult its own technical sheet rather than treating this table as an all-brand E70XX chart.

When a published range is broad, the qualified procedure may set a narrower operating window. Maintain the correct electrode storage and condition, especially for low-hydrogen products, and do not assume that changing diameter leaves the procedure unchanged. Record the product, class suffix, size, current type and actual machine setting in the welding documentation when traceability is required.
