It’s important to push the weld forward and hold the nozzle at a 10- to 15-degree angle to keep the shielding gas out in front of the puddle. You also want to maintain an even, steady hold. Don’t loop your puddle as you would when welding steel. The arrows point to places where we stopped and restarted on our first practice run. Our heat was also a bit low. With aluminum, try to maintain your weld from start to finish with no stopping. As the weld progresses, you’ll need to really speed up as the material rapidly gains heat.
