Welding and Manufacturing
PSPQ’s HUB Trailer parked along side our power intake lines to prove their system would condition my power through Power Faction correction and Harmonic Filtering

The welds on all our new construction was stronger than I had ever seen, especially when we x-rayed the welds, which is required for our line of work in the certification process under government inspection. The guys at PSPQ explained that we had higher quality welds because of the efficiency of the clean power supply. This resulted in fewer re-welds after X-Rays of the welds showed a lower failed rate due to the previous poor power quality.
I was shocked to see that we maintained our 3 shifts of welding, grinding and polishing all done with less electricity; and our motors were all running cooler due to the difference the PSPQ systems had made. I held my iPad tablet in our conference room and I could see our customized dashboard at a glance, remotely monitoring all the motors running in our 3 plant facilities. I even got notifications on my mobile device in real time.
American Welding Story
My grandfather started this welding and fabrication shop after coming back from World War II. We’ve been serving the aerospace industry ever since — three generations of hard work, precision, and pride. These days, we’re building parts that end up on everything from satellites to jet engines, so there’s no room for error. Weld quality has to be perfect every time.
Lou’s Initial Skepticism
I’ll be honest — when they first told me power factor and electrical harmonics could be affecting our weld quality, I was skeptical. I’ve been doing this a long time, and I always figured if the lights were on and the machines were running, we were good to go. But the PSPQ team walked me through the data. They showed me how voltage instability and poor power factor could cause fluctuations in arc behavior, especially with some of our more sensitive TIG and robotic setups.
Still, talk is talk — so I asked them to prove it.
Our welding equipment ran optimally.
They hooked up their monitoring equipment and recorded a week’s worth of data from our main panel. The results were hard to argue with. Our power factor was dragging well below 0.75 at peak load, and we were seeing harmonic distortion at 5% in the waveform that lined up perfectly with the times we were having weld issues.
