If you want your metal fabrication shop to expand and offer more services, you must consider investing in welding technology. However, selecting the right welding machine can be difficult and time-consuming. To make it easier for you, we’ve compiled this guide on how to choose the right welding machine for your business. Factors to consider include space constraints and budget restrictions, as well as knowing what type of welds you plan on doing for materials of various types and thicknesses.
Understand Your Needs
Ask yourself what materials you’ll be welding and their thicknesses. These factors can greatly impact your choice of welding technique and equipment.
If you’re working with thick materials, look for a welding machine with strong amperage capabilities and versatile features. On the other hand, if you’ll be working with thin materials, machinery with precise control and low amperage capabilities could be a better fit. Taking the time to understand your needs will help you select the right tools for the job and ensure successful welds.
Type of Welding
Welding is a highly skilled trade that requires an understanding of a variety of techniques. Your shop may use a sophisticated fiber laser tube cutting machine to create precise lengths of pipe. You might also use bending machines to create different components of a piping system. You’ll need a welding machine in the hands of a skilled welder to join those pipes and form necessary configurations for the project. Discussing the different methods of welding with an experienced welder is a good place to start when purchasing welding equipment.
One popular welding technique is MIG, also known as metal inert gas or gas metal arc welding (GMAW). This technique requires welders to use an arc with a consumable wire electrode as the filler material and shielding gas to protect the weld on the metals. The welder can adjust the heat using a foot pedal.
Another technique is TIG, or tungsten inert gas welding, which produces precise and high-quality welds using an arc and a non-consumable electrode made of tungsten with a separate consumable filler plus a shielding gas. Laser welding uses a laser beam to join the materials. Each welding technique has unique advantages, so it is vital to choose the right one based on the type of material you’re working with, its thickness, and the welding position.
Power Source, Amperage, and Voltage
One of the biggest decisions you’ll need to make is whether you want a gas-powered or electricity/battery-powered machine. Electric machines are more precise and reliable than gasoline-powered machines but require a power source at the workstation. Gas-powered machines offer portability but are less reliable and require ventilation. Ideally, you would work outdoors with a gasoline-powered machine, so keep your workspace in mind before making a decision.
The other key factors to consider are the amperage (the volume of electrons in an electrical current) and the voltage (the force or pressure that allows the electric current to flow) for your specific projects. Thick materials require higher amperage and higher voltage than thin materials. Carefully examine the recommended electrical safety precautions when choosing an electric welding machine.
Machine Size
Consider your available space before choosing a welding machine. A small machine may not be able to handle your workload, resulting in long processing times and reduced productivity. On the other hand, a machine that is too large may take up valuable space that you could utilize for storage or other equipment.
Machine Portability
Having a welding machine that you can easily move around can be incredibly beneficial, depending on the type of work you do. If your team of professional welders needs to travel to different job sites, portable welding equipment provides the necessary flexibility. You can select a large stationary welding machine if you’ll be doing most of your welding jobs in-house as part of your fabrication services.
Safety Features
Modern welding machines are equipped with a variety of safety features to prevent accidents and ensure a safe work environment. Unique features, including automatic shut-off systems that kick in if the machine overheats and insulated handles that protect against electrical shocks, give welders peace of mind and help them stay focused on the task at hand.
Other important safety features include low-voltage protection and ground fault interrupters, which prevent electrocution. Built-in fire suppression systems can quickly extinguish flames before they spread. With the advanced safety features on many modern welding machines, you can ensure both safety for your team and efficiency from your welding machinery.
Brand Reputation and Warranty
Welding machinery can be a major investment for a small fabrication shop. When investing in a welding machine, ensure you are getting a product that’s going to last a long time and withstand heavy use. This is why brand reputation is crucial. You want to choose a well-known, respected company with a proven track record to give you the assurance that your investment will be worth it. Combine that with a comprehensive warranty, and you can feel confident that your welding machine will be an asset to your work for years to come.
Maintenance Services
Investigating the maintenance services that come with your welding machine can be a game changer in keeping your equipment running smoothly and efficiently. Sellers frequently provide varying levels of coverage, which could include routine maintenance checks, repairs, and even replacement parts. Taking advantage of these services can save you time and money in the long run. Read the fine print to understand your warranty and maintenance plan.
By taking all of these factors into consideration, you can choose the right welding machine for your business. Welding systems that are well-suited to your daily tasks offer versatility, portability, power, and safety features. In addition, you should take note of the seller and the brand’s reputation, warranty, and service options in case something goes wrong or needs repairs. Mac-Tech can provide a professional perspective on various welding methods and machines that are compatible with the types of metal you work on and the products you create.
