Does Marijuana Cure Glaucoma? | Marijuana

In the 1970s, a man named Robert Randall who suffered from glaucoma sued the federal government because they had conducted studies showing that marijuana could relieve the pressure, the intraocular pressure from the eye. That is to say they federally funded studies done at UCLA showed when you actually used a medical device, the pressure […]

What You Need to Deep-Fry Foods | Deep-Frying

Great, so you can use a vast amount of different implements to fry at home. I mean we obviously have the mother of all fryers here, which commercially we use. This, you can pan fry an egg and nothing else. These two are perfect for pan frying. You don’t want to deep fry in them. […]

What Is Flux? | Soldering

Flux is a very important part of soldering. Flux is necessary to reduce the oxides that tend to form whenever you have hot metals in contact with the air. In electronics, we use a rosin-core solder or a mild solder or water-soluble solder. Make sure that you choose something that’s not plumbing flux or acid-core […]

Soldering vs. Brazing vs. Welding | Soldering

So soldering is useful for electronics and joining copper metal. And it’s a process wherein the base metal stays solid and doesn’t melt. The solder itself melts, but the copper stays solid. In that way it’s very, very similar to brazing, which is another technique in that the base metal also stays solid. Now, brazing […]

How to Properly Move & Feed the Rod | Welding

Two of the most common mistakes beginners find is either moving your welding rod too quickly across the seam, or too slowly. I’ll demonstrate both. [pause] Here you can see two good welds flanking a weld that was done too quickly. A good weld, and good speed is indicated by a good spacing between these […]

How to Properly Fit & Clamp Pieces | Welding

Ninety percent of all welding is really down to fitting. If pieces are fit and cut carefully, the welding process is a snap. If they’re fit poorly, or there are large gaps, it can consume a lot of time, welding rods, and patience to get a good weld. I’m going to go through and deliberately […]

What Is Welding? | Welding

What is welding? Welding is distinct from other processes that we use to join metal, such as soldering and braising, in which a third material is added as a kind of glue. With welding, we take two distinct materials, two distinct objects. Through the addition of heat we create a molten pool of metal into […]

What Is an Arc Welding Machine? | Welding

What is arc welding? Today I’m going to be talking about and demonstrating shielded metal arc welding that’s sometimes referred to as stick welding. Arc welding creates heat for the welding process through a process of electrical resistance. The arc welding machine builds up electrical potential in the same way that all of you have […]

Common Beginner Mistakes | Welding

I’m going to try to demonstrate some of the most common problems or mistakes that beginning arc welders encounter. One is which the arc will not start, or the arc rod sticks. Neither is cause for panic, and is usually the result of one or two things. Either your voltage is set too low or […]

How to Pick a Welding Rod | Welding

Selecting the right welding rod is critical to the success of your welding job. You see here before me four different kinds of welding rods. They vary in three important ways. One is diameter from 5/32 to 1/8 to 3/32 to numerical number 6013 in this case, 6011 here, and 7014 here. This last set […]
