Welding Electrode J421 - A Reliable Choice for Alloy Steel Welding

The welding electrode J421, also known as AWS A5.1 E6013, is a rutile type electrode suitable for welding low carbon steel structures. It is especially effective for welding thin plate steel with short discontinuous welds and the requirement of a smooth welding pass. This electrode offers excellent welding performance with a stable arc, little spatter, easy slag removal, and reignition ability.

Applications:

• Low carbon steel structure welding
• Welding of thin plate steel with short discontinuous welds

Characteristics:

• Can be used with both AC and DC power sources
• Suitable for all-position welding
• Stable arc
• Minimal spatter
• Easy slag removal
• Reignition ability

Attention:

In general, there is no need to re-dry the electrode before welding. However, if it becomes damp, it should be re-dried at 150°C-170°C for 0.5-1 hour.
