Proper Care and Maintenance for Welding Machines

The preventive care and maintenance of the welding equipment are two of the most important factors that allow extending the useful life of the equipment, as well as the execution of strong and high-quality welds.

On the other hand, the constant care and maintenance of the welding machine will result in significant savings of time and money, as they will avoid damage to the machine and errors in the execution of the welding.

Although there are several types of welding machines, there are some standard criteria that must be managed for the maintenance and preventive care of any welder. Below, then, we detail what care and maintenance we need to take into account to preserve our work tool.

General Preventive Care for a Welding Machine

The care of the welding machine, as well as any other work equipment, is mainly based on simple actions that must be performed before, during and after use. So, how to do good general maintenance of the welder?

Before starting the execution of the work:

  • The first action to be performed is to read and understand the user manual corresponding to the welding equipment. Be sure to follow all the steps in the user's manual before operating the welder.
  • You must verify that the welding machine is connected to the mains with the correct voltage.
  • Welding equipment must be located in a safe place where no object can accidentally fall on it.
  • Check that all the wiring of the welding machine is in good condition before starting work during the execution of work.
  • Keep your workplace tidy and clean. You must avoid contact with the tool with any source of liquid while it is in operation.
  • Keep any flammable objects out of reach of the welding spot at the end of the work.
  • Be sure to turn off and disconnect the equipment from the power source.
  • Keep the welder in a dry and tidy environment.
  • Visually inspect equipment components for overheating, loose connections, obstructions on fan blades, and proper operation.
  • Another task that is part of preventive care for a welding machine is its cleaning. For equipment that is used in work areas with a high concentration of dust and especially metal particles, cleaning of the welding equipment must be performed daily. In the case of machines that are used in a cleaner working environment, cleaning can be done monthly.
  • To carry out the cleaning process, you must first disconnect the engine from the electrical connection and lift the welding equipment cover. To remove dirt from the welder, apply clean, dry compressed air to its components. Care and maintenance for electrode welding equipment. This type of welder is not very demanding regarding maintenance; however, some additional recommendations to the general care should be taken into account when talking about electrode welding.

In addition to the internal components of the machine, this type of welding equipment has the electrode clamp and the mass clamp, which do not require meticulous care, but should be evaluated to verify the state of wear they present, and replace them when necessary.

Another element to take into account are the electrodes; these must be kept in a dry place and protected from moisture. The idea is to place them in a closed, dry and strong container that protects them from possible blows and dents.

Care and maintenance for MIG/MAG welding equipment. This type of welders that are applied for MIG/MAG welding has many more peripheral elements, which require a little more attention at the time of carrying out the maintenance of the equipment, given the number of components that it possesses.

The pinch rollers and the gun guide: as the welding wire passes through these elements, it is possible that in its path it carries dirt or residues from the work area, which can accumulate inside. Therefore, it is recommended to clean these elements, using compressed air, dry and clean, on a weekly basis.

Another option for cleaning the rollers is to remove the rollers and clean them using a wire brush. To check and clean the rollers you must first turn off the winder.

The welding wire: it must be cut to the correct length. If this is too short, the powder can accumulate between the retaining head and the coating, generating problems with the winder. It is also essential to keep the welding wire completely clean, to avoid contaminating other components of the equipment and also to obtain a perfect weld.

The pistol guide: it must protect the pistol from any object that may fall on it or the pistol cable. Also, avoid dragging these items.

The nozzle of the gun: it must always be kept free of dirt or dust, to allow the correct flow of the gas and the proper execution of the weld. Also be sure to store the nozzle in a safe place to avoid dents or other damage.

The diffuser: this is another of the components that must be checked and must be kept free of any obstruction. To clean the diffuser, remove the cone and use a wire brush to remove all dirt.

Contact tips: to protect the condition of the welding tips, it is recommended to avoid contact with the working material. Every time the tip contacts the workpiece, the tip is damaged. The contact tips over time will need to be replaced, so it is essential to be attentive to the time of change so that it does not affect the welding work.

The gas hose: it is essential to make sure that the hose is never bent to keep it in the best possible condition. You should also perform constant inspections of the hose to rule out possible leaks.

Gas bottle: this is one of the components that require essential attention. You should verify that the bottle is always firmly attached to the wall or welding machine. You must prevent the container from falling and causing an accident. Once your work is finished, it is recommended to remove the regulator and place a screw cap preferably on the bottle, this to prevent any leakage and to maintain the safety valve system.

Care and Maintenance for Inverter Welding Equipment

For the care of this type of inverter welding machines, it is sufficient to follow a few recommendations during use and for regular maintenance.

Before and during the use of the welder:

  • Check that the voltage and frequency of the welding correspond to the voltage and frequency of the network available in the workplace, before making any electrical connection.
  • Protect the power cable of the machine from external agents such as oils, cutting elements and heat. Arrange the wire so that it will not be disturbed or exposed to deterioration while working.
  • While the welder is in operation, never obstruct its ventilation grilles, this will help maintain service values.
  • To support the excellent condition and safety of this type of welding machine, it is highly recommended that it be serviced on a regular basis.
  • Note: After disconnecting the machine from the power supply, you must wait 5 minutes for the capacitor to discharge to a safe voltage (less than 36 V).

Daily Inspection

  • Before starting your work, make sure that the knobs, front and rear switches are easily operated. If one is not administered correctly, repair it or replace it immediately.
  • Check that the indicator lights light up correctly.
  • Make sure that the fan works properly and does not generate knocks, otherwise do not use the welding machine until the fan is repaired.
  • Observe if the quick connectors are loose or preheated. Also, make sure that the cables keep their insulation intact, never work with repaired cables or without their insulating coating.
  • After turning off the welding machine, check internally for crackling, whistling or any peculiar odor. If some of these situations arise and you do not understand why, contact the professional service.

Monthly Maintenance

  • With the use of dry compressed air, clean the inside of the welding machine. It is the primary objective of eliminating the accumulated dust from the primary voltage transformer, radiator, IGBT module, inductance, covers, and PCB.
  • Check for loose or missing screws, and tighten or replace.

Maintenance Every Three Months

  • If the model of your welder has a led viewer, verify that the reading is the same as when measuring with an amperometric clamp.

Annual Maintenance

  • You must measure the insulation impedance between the primary circuit, the sheet metal box, and the PBC if the reading is less than one, the insulation may be damaged and requires replacement or reinforcement by drying.
  • Please note that any repair that involves the disassembly of the welding machine must be done by professional personnel.
