I want to talk about welding safety. The first thing you want to make sure is that you have an appropriate space to do your work. You want to have a clean, dry shop. Water and welding don't mix. You want to make certain that you have a nice cement floor, or dirt. Some of the best studios I've had in the past have been simple sheds outdoors with a dirt floor.
You want to make sure you have adequate electricity. Most welding machines take either 220 or 240 volts. You shouldn't mess around with that yourself. You should make sure that you get a qualified electrician involved if you need to.
You want to make sure that you have adequate ventilation. In our shop, because we're in a closed environment, we used what's called a point ventilation system. This exhausts most of the fumes directly at the welding source. In a simpler setup, if you're outdoors you're going to have plenty of natural ventilation, but you always want to make sure you have some kind of exhaust fan. Keep the doors open.
You also want to make sure that your work space is clear of any kind of flammable materials - no paper, no books, no lumber. You want to have that space as clear and dry as possible. If you do have an accident you want to make sure that you have an appropriate fire extinguisher close at hand.
Of course, you want to have good lighting. Good lighting makes for good work and a safe work place. Your gas bottles, we have here an oxygen and acetylene set up, it's very important that these bottles are secured to the wall or to a designated bottle cart.
Before you start working every day you should check your connections, gauges, and torches for leaks and/or cracks in the hoses. You want to make sure in your work space that your welder is in a clean and dry location. Water and dust are the enemy of machinery. It's also good practice to make sure that your welder is unplugged when not in use.
