Manual Arc Welding (111)

Manual Arc / MMA Welding World

The indestructible method for construction sites, installation, and extreme weather. Works without a gas cylinder—even underwater.

Electrode & Current Calculator

Determine the ideal amperage based on the core diameter and insulation.

Electrode core diameter:
Enclosure Type:
Recommended Welding Current:~ 117 A

Note the polarity: Alkaline electrodes are almost always connected to the positive terminal (+); cellulose electrodes depend on the type!

Master's Requirement: Post-weld drying of basic electrodes (E7018)

Alkaline coatings attract moisture! For seams subjected to dynamic stress (cranes, bridges), it is ESSENTIAL to dry them in an oven at 300°C–350°C for 2 hours to prevent hydrogen cracking.
