How can we save energy in welding?

There are many different ways to save resources in welding, including the resource-conserving production of welding machines, the use of long-lasting, repairable, and recyclable equipment, opting for multiprocess machines and equipment, and the optimized application of wear parts. But is there much scope for reducing electricity consumption?

How much energy does a welding machine use?

In terms of the electricity costs of the individual machine, this may seem rather negligible. But with countless welding machines in use around the world, the higher consumption of 255 kWh per year does make a difference in terms of overall energy consumption, the required power plant capacities, and the energy costs.

Why should you use a modern welding machine?

Beyond this, it’s advisable to set modern welding processes on the machine. These can make welding simpler, higher quality, and usually more energy-efficient too: the cleaner the work of the welding specialists, the less rework required, and the lower the overall energy consumption.

How does a welding process affect energy consumption?

Welding processes that ensure higher welding speeds with the same or improved arc stability also have a positive effect on energy consumption. A good example of this is the Pulse Multi Control (PMC) welding process.

Is a welding torch energy-efficient?

Unfortunately, this is not always particularly energy-efficient—in many older welding machines, the coolant constantly circulates at the same speed, regardless of how much energy is introduced into the arc and therefore how much heat is generated at the tip of the welding torch.

How much electricity does an inverter welding machine use?

The results were clear: the older inverter welding machine consumes 255 kWh more electricity per year. In terms of the electricity costs of the individual machine, this may seem rather negligible.
