Is it hot and humid in your location? If so, I have one very important tip for you. If you are sweating, don't let the rods rest on your bare arms. You will get a buzz. Also, if you find yourself in tight quarters, laying on your side and welding upside down, and you can't figure any other way to press the foot pedal except by using your knee, make sure you're wearing long pants. These are valuable tips. Don't ask me how I know...
