Usage Instructions

Use DC+ (preferred) or AC with high OCV. Clean base material thoroughly and bevel thick joints to 60°. Preheat to 200–300°F for thick sections or cold environments. Maintain short arc and steady travel speed. For enhanced performance, PWHT at ~1150°F may be applied based on base metal requirements.
