Hey. They ain't that bad.
You are getting penetration.
Just practice steady movement of the rod.
Clean your metal well first. It can help.
Read about the ideal angle to hold your rod to the work. Not vertical, not too shallow.
One of the biggest factors for beginners is a user friendly rod. Our instructor bought us Oerlikon Overcord rods. They were great. Match the rod dia to the thickness of the plate. Just read up. Same for power setting, read up and set according to the rod, plate and type of joint. Then experiment with more and less amps to see how the weld changes.
Secret is to understand how changing something changes rhe weld. Trial and error is a good teacher but systematically change one thing and learn its effect.
It's a craft skill. You'll be great. Just put in 10-20 hours of structured practice.
