663 Self Shielding Mild Steel Flux Core Mig Wire .045X33LB

• Self shielded — no gas required, great for windy conditions
• Outstanding out-of-position characteristics
• Referred to as the 7018 wire
• Low spatter — less cleanup
• Easy to use
For best results remove any base metal contamination (dirt, grease, rust, scale, etc.). Most materials can be welded without preheating; however, some materials are best welded with preheat because of the base metal composition. USE DCSP. For best results chip slag between passes and slow (air) cool. A leading gun angle (backhand technique) increases penetration for multipass welds. A lagging gun angle (push technique) decreases penetration for thin materials and out-of-position welds.
