Automatic Spot Welding Equipment and How Welders Work
Automatic spot welders have become increasingly popular among construction workers due to many reasons. In today’s tough economic times more of us than ever are seeking to perform cheaper and more effective welding jobs. When you are working on an auto shop floor, you already know that your workdays tend to be very limited. Your energies are primarily spent on making sure the shop is stocked with the needed tools and supplies that will keep you going throughout the day and into the evening. The addition of an automatic welding system to the shop floor allows for an increase in efficiency and reduces your chance of missing a weld, especially if you happen to be working late into the night.
One of the first things most new shop owners and operators learn is that using a typical hand held torch combined with a standard ball point pen or pencil is simply not enough to allow one to weld on heavy parts. Most welds require a high heat even beyond the melt stage that takes several minutes to reach. This creates a problem for most new wearers because most welders rely on a tip dresser to assist them in the joining process. Using a tip dresser helps to increase the welder’s ability to join pieces of metal with ease and reduces their chance of missing a weld or causing excessive heat damage to the workpiece.
Automatic welding machines also often incorporate other features that help the operator to complete the welding process more efficiently and more accurately. Many times automatic welders include automatic torch control. This feature allows the operator to slow down or speed up the flame in order to control the amount of heat that is generated and used on the welding machines torch. The increased control allows the operator to make precise adjustments to the torch settings without taking his eyes off the work.
The most commonly used type of Automatic welders is the Continuous Flow Auto Welding machine. These welds are used in a wide variety of industries such as automobile repair, aircraft manufacturing and oil drilling. In these applications, there are typically two types of electrodes. The first set of electrodes is commonly called the feed welds. These electrodes are placed over the work piece to which the hot gases will be directed. The second type of electrodes is called the gas feed welds, and these electrodes are placed directly on the workpiece.
The use of tumblers in automatic spot welding equipment is common in many types of welding. The tumbler acts as a force multipoint device that combines the arc energy with the mechanical energy of the tumbler. Because it is a mechanical system, the tumbler allows the welder to maintain a steady arc and the tumbler also allows the welder to complete the arc without having to regulate the flow of gas into the torch or interrupt the torch prematurely. Due to the tumbler’s mechanical advantage, the welder can maintain a consistent, long life span when welding with this equipment.
The welds that are produced by Automatic Spot Welding equipment come in two types, the Direct Feed and the Indirect Feed welds. The difference between these two types of welds is that the Indirect Feed welds use a continuous feed mechanism where the filler metal is fed over the welds while the direct feed uses a semi-automatic mechanism wherein the filler metal is fed over the welds by a mechanism that causes the filler metal to be pushed to the welds. The two types of electrodes that Automatic Welding machines use have a great effect on the quality of the welds that are completed. It is important that the welder use the correct electrodes for the job at hand. Automatic welders will commonly need to be calibrated and may even have additional settings that need to be adjusted based on the material being welded and the manufacturer’s recommendations.
