Drawing of an electrode holder welding with a covered electrode, with slag covering the bead

The easiest process to take to the field, explained from the covering to qualification.

The covered electrode still welds where the wind blows the gas away and no wire feeder can reach: construction sites, pipelines, repairs and erection. This course covers the power source, what the covering does, how to read a classification, storing low-hydrogen rods, settings, positions and the defects of the process.

A free theory course from the Steel Knowledge Hub of Indumor.

Who it is for

Welders, technical school students and site supervisors. You do not need to know how to weld to start.

Method

The same as the MIG-MAG course: one principle per lesson, shop numbers and a self-test at the end.

Pace

The eleven new lessons and both appendices are published; lesson 2 is the history of electric welding. The TIG course comes next.
