Horizontal Mig Weld

Determine the thickness of your material to be welded and check your welder’s recommended settings on the inside panel. We use these as a loose guide, finding we normally like to run a bit more heat and a bit less wire speed than what’s spec’d. Attach your ground clamp and position your nozzle. For a horizontal MIG weld, hold the nozzle at a 10- to 20-degree angle to the work and push into the weld to keep a flow of shielding gas out in front of your weld puddle to better combat porosity. For deeper penetration, reverse the nozzle direction and pull the puddle.
