Sometimes that just more practical to handle welding work in the ar instead the the convenience of your shop.
You are watching: How many watts does a welder use
Today’s generators and also welders are much more powerful and also portable, make it much easier than ever to weld at remote locations, but what dimension generator because that welding is right for you?
Get the appropriate Amperage Value
Depending ~ above the welder, friend may discover a handful of different amp ratings, or simply one.
Look because that the I1max number. It’s the best rating to use because it to represent the maximum rated it is provided current. You may see this described as the best “inrush” or “surge” existing draw top top startup.
Using the specs Lincoln gives us:
20 amps x 120 volts = 2400 watts
But I’ve seen Lincoln to represent say this welder requires, at a minimum, a 3000 watt generator. And 3000 watts divided by 120 volts offers us 25 amps, which is likely closer come the I1max rating because that this machine.
The encourage circuit breaker size might be too small to calculate complete operating wattage. A correctly operating circuit breaker is designed v a time delay and most likely wouldn’t trip due to the fact that of a quick 25 amp surge.
But this would reason a difficulty on a generator with a rise rating that 2400 watts.
Finally, don’t make the mistake of utilizing output amperage figures such as I2 or duty bike amperage.

“Dirty” vs. Clean strength Generators for Welders
Welder inner power sources loss into 2 distinct design categories, each handling incoming current in different ways to produce weldable power output.
With technology to produce efficient welding strength with lot smaller transformers, inverter welders frequently weigh less than fifty percent of timeless welders. They attain a an extremely stable output many thanks to capacitors that store high voltages.
But these advanced electronics require quality intake power.
Many generators develop excessive voltage and also frequency fluctuations well-known as “dirty power”. It’s measured as a percentage of full Harmonic Distortion, or THD. Dirty power have the right to quickly damage sensitive electronic devices or shorten service life through cumulative damage.
Particularly sensitive room older inverter welders using metal-oxide semiconductor field-effect transistor (MOSFET) technology.

Newer machines based upon insulated-gate bipolar transistors (IGBT) fare better, yet still call for a clean strength generator through 5% or less THD.
