Question

use the spec sheet for the hobart 610 - e6010 electrode to answer the following questions.

what type of current should it be used with?

dcep
scen
dcep or dcen
none of these

Explanation:

Identify the electrode classification

Using the AWS Electrode Classification knowledge point, the electrode specified is E6010. In the AWS classification system for shielded metal arc welding (SMAW) electrodes, the last digit "0" indicates the type of coating and the compatible welding current.

Determine the compatible current type

Using the Welding Polarity and DCEP knowledge points, an E6010 electrode has a high-cellulose sodium coating. This specific coating is designed to operate exclusively on direct current electrode positive (DCEP) to achieve deep penetration and a stable arc.

Answer:

• DCEP (Correct answer)
• SCEN
• DCEP or DCEN
• None of these
