I live in the USA. I drove truck for15 years. Then I had to switch careers.I went into building dental x ray machines. Took a basic electric course in college. Left the x ray company to work on assembling cell phone towers electrical controls. I then Left their to learn welding. I am a state certified welder fabricator. So for the past 17 years I have been building food grade and chemical grade tanker trucks. I now am on my WA journey and want to learn to help others here .
