If you are in the market for welding machinery and accessories, perhaps automatic spot welders are the perfect equipment for you. These machines are perfect for industrial applications and when you need them, they can make welding a breeze. Automatic spot welders on sale nowadays are readily available both for purchase and also on rental. Many of the newer models are built with long life in mind. They can literally last a lifetime.
The basic model is the straight-line electric puddle welder which has the ability to weld in wet or dry locations. The second is the wet/dry weld which is made up of a heater that automatically adjusts temperature on the welding arc. It comes in handy in applications where a welder needs to be nearby but cannot get too close to a wet or moist area. And finally there is the gas welders which has a filler metal feed that feeds metal into the hopper via tubing. All three of these equipment models have their own distinct advantage. Their primary selling points are ease of operation, power capacity and portability.
Welder electrodes come in many shapes and sizes and there are also many different types. There are electrodes made from both steel and copper and all three come in different degrees of resistance to heat. There are also electrodes made out of different types of plastics. The most popular are stainless steel, copper and nickel. When purchasing automatic spot welding equipment for sale, it is important to know which type of electrodes will work best for the job you need to complete.
When working with any type of welding electrodes, it is important to ensure they are clean and free of debris before starting to work on a specific work piece. It is common for welders to use tungsten oxide, lead, sulfur and flux cored electrodes. These three are the most commonly used and are available in a wide range of different sizes. Most people however will work with either two types of electrodes:
Once the electrodes are charged and ready to go, the welder will connect them to a welding gun and start the process. Most people prefer to start their work by starting in a separate work piece, such as a puddle or a weld puddle. If you want to start your weld puddle, ensure that you have two types of electrodes – a pair that are the same size should do the trick, otherwise use one of your smaller conductors. When connecting the electrodes to the gun, ensure that they are loose enough that they can move around the gun without rubbing up against each other.
The next step is to place the tumbler into the work piece. This will be done by turning the tumbler to the side so that it points towards the work piece you are working on. Now place the tumbler over the weld area and place the gun over the weld and squeeze the trigger for the tumbler to rise up to eye level. It will take about thirty seconds to rise the tumbler to eye level before squeezing the trigger again.
