How Many Amps to Weld 1/4 Steel: Finding the Perfect Setting

ByWelderology Team

Welding 1/4-inch steel is a common task in fabrication shops, automotive work, and heavy-duty repairs. However, getting it right requires more than just skill—it demands the correct amperage setting. Using too little current won’t provide sufficient penetration, while excessive amperage can lead to burn-through or distorted metal. Understanding the amp requirements for different welding processes…
