Mig welding in tight places. We are welding rotors for a micro hydro electric turbine. The rotor looks a lot like a heavy duty squirrel cage fan but the spaces between the blades is tight. The space is less than 3/4 inch and the blades are curved like on a squirrel age fan. My M-15 mig gun can fit in but there is no room to angle it to weld in the corners. Now we bend our stick rods and weld around the corner. I would sure like to use the mig if possible. Have thought of trying to bend the tip to throw the wire off to the side or add a finger to the end of the tip to bend the wire side ways after it is out. Any body out there who has ideas? AlG
