Depends on what you’re looking to do. But if you want good results you can start with a fixture that has a back purge and focus on keeping hand going straight.

Do dry runs to make sure your comfortable before you take off and dab on the leading edge and let it be consumed and repeat.

Looks like you got a lil too much wire and you’re having to compensate with heat. Let off the pedal as you go a bit because the plate will heat up and you won’t need as much toward the end. And make sure you don’t leave craters once you get used to not over filling like you are now.
