Welding Guidelines (Continued)
PUSH VS PULL TECHNIQUE
The type and thickness of the work piece dictates which way to point the gun nozzle. For thin materials (18 gauge and up), the nozzle should point out in front of the weld puddle and push the puddle across the workpiece. For thicker steel, the nozzle should point into the puddle to increase weld penetration. This is called backhand or pull technique (See Figure 11).
