Covered electrodes can be affected by moisture, broken packaging, contamination and rough handling. Store cartons clear of floors and walls where dampness may collect, protect them from rain or chemical exposure and avoid unnecessary movement of open packets.

Where a product requires controlled baking or rebaking, follow the product-specific instruction supplied by the manufacturer.

General mild-steel fabrication commonly uses E6013-type products, while restrained structures, higher-strength materials, low-hydrogen work, hardfacing, cast iron and stainless applications require more specific selection. Share the material, thickness, joint, position, machine and service condition before finalising the product.

For applicable mild-steel E6013 portfolio products, indicative guidance includes approximately 60–90 A for 2.50 mm, 100–130 A for 3.15 mm, 140–180 A for 4.00 mm and 180–240 A for 5.00 mm electrodes. Machine characteristics, polarity, welding position, thickness, joint design and operator technique affect the final setting.

Low current may produce unstable arc, poor fusion or slag interference. Excessive current may increase spatter, undercut, overheating or burn-through. Check arc stability, bead profile, penetration and slag behaviour before continuing long runs.

For porosity, arc instability, slag inclusion, cracking, poor bead appearance or unusual spatter, share the product, size, visible batch detail, current, polarity, position, base material, preparation, storage history and photographs of the joint, weld and packet label.

• Use suitable ventilation or local exhaust near the arc.
• Keep your head out of welding fumes.
• Wear suitable eye, face, hand, hearing and body protection.
• Do not touch live electrical parts.
• Inspect leads, holders, earthing and the work area before welding.
• Read product labels and safety information before use.

Include the product, size, company name and purpose of the request—purchase, tender, vendor approval, safety file, distributor onboarding or technical review—so the correct document set can be prepared.
