The Importance of Welding Machine Maintenance

Welding Machine Maintenance

Following a regiment of appropriate and thorough maintenance procedures allows a welding machine to run safely and dependably for a long time. Improper, incomplete or totally neglected maintenance can not only result in equipment failure, but it can also lead to serious hazards including severe injury or even death. With some forethought and basic planning, welding machine maintenance is extremely easy.

Electrical Systems

Electricity plays a significant role in welding, as it is the primary power source for most welding processes, oxy-acetylene gas welding being the only exception. The dangers of electricity are huge, and the consequences of accidents resulting from problems with electricity include debilitating injury or death. These risks necessitate regular inspection of all electrical components incorporated in your welding machine. This includes the following routine practices:

  • Disconnect all of the power units and blow out or vacuum the machines interior at least once every six months.
  • Check and clean (with a wire brush) the wire feeder and drive rolls (replacing if necessary) at least once every three to four months. In addition, inspect and cleaning (or replacing if necessary) the inlet and outlet guides.
  • Arrange for a technician to service the welding gun and liner assembly at least once a year.
  • Inspect all of the electrical cables at least once a month for signs of wear, including cracks and breaks, immediately replacing any cables with excessively worn or damaged insulation.
  • Inspect electrical safety equipment on a monthly basis to ensure circuit breaks and interlocks are functioning properly.

Shielding Gas Cylinder Maintenance

Always store shielding gas cylinders in a cool and dry environment. Also, make sure to keep them in an upright position. Inspect and test regulators and valves at least once every six months to make sure there are no leaks or breaches that are causing incorrect pressure readings.

The hoses need to be coiled up for storage. This will prevent damage from prolonged kinks that occurs when hoses are improperly stored or stepped on when left on the ground. Any creaked or damaged hoses require replacement immediately.

Routine Maintenance Schedule

The following are routine maintenance schedules by the hours:

8 Hours Maintenance

  • Wipe up oil and fuel spills right away
  • Check the fluid levels (oil and fuel)
  • Service the air filter

50 Hours Maintenance

  • Service the air filter element
  • Clean and tighten the weld terminals

100 Hours Maintenance

  • Chang the oil
  • Change the oil filter
  • Change and tighten the battery connections
  • Clean the cooling system

200 Hours Maintenance

  • Replace the unreadable labels
  • Replace the fuel filter
  • Check the valve clearance

250 Hours Maintenance

  • Check and clean the spark arrestor

500 Hours Maintenance

  • Tape or replace cracked cables
  • Clean/set injectors

1000 Hours Maintenance

  • Blow out or vacuum the inside of the equipment. Make sure to do this monthly during heavy service.


Creating and staying on top of a regular welding machine maintenance schedule allows you to not only ensure your equipment works when you need it most and lasts for many years to come, but also operates at peak performance, guaranteeing your safety.
