Manufacturer reference configurations

Compare published specifications for each configuration, then select a reference or enter your own requirements. Supply and the final configuration are confirmed in the quotation.

20 documented configurations. Review one specification at a time; your custom requirements are retained.

E7018-1 H4R · 2 × 300 mm

One documented SMAW configuration. Verify base-metal grade, welding procedure and supply pack before quotation. Published current or gas information applies to this reference only.

Your specification

Configure your product requirement

Enter the capacity and site requirements you need. Your selections carry into the RFQ and remain editable before submission.

Essential operating requirements
Additional dimensions and application details
Equipment identification

Identify the equipment for this application. Add nameplate photos or the equipment specification in the RFQ attachments step.

Next: contact details, quantity and delivery. Leave unknown requirements blank and request help in the RFQ.

Applications

Fabrication, repair and industrial maintenance; final filler selection depends on base-metal grade, joint design and the qualified welding procedure.

Selection guidance

Choose the classification, then the documented diameter and length pair. E6018 (mod.) remains distinct from an unmodified E6018 request. For E6010, the source distinguishes normal DC+ operation from DC- root-pass operation. Enter your base-material grade, joint, position and qualified procedure separately.

Technical notes

Published sizes are specific reference executions. Packaging, batch certificates and delivery availability are confirmed with the quotation. Requirements for another grade or size remain visible separately.
