Power Sources
A welding power supply provides an electric current for welding. A constant current (CC) machine varies output voltage to maintain a steady current, while a constant voltage (CV) machine fluctuates output current to maintain a set voltage. Shielded metal arc welding (SMAW) and gas tungsten arc welding (GTAW) use a CC source, and gas metal arc welding (GMAW) and flux-cored arc welding (FCAW) typically use CV sources, though constant current is also possible with a voltage sensing wire feeder.

The next generation of welders, guns and torches are prepared to handle your job shop’s application challenges. The latest innovations and advances in MIG/TIG welders, guns and torches link fabricators to a wide range of products to successfully overcome hitches in the fabrication process.
Advances increase both power and performance in arc welding, including the ability for users to cut through thicker material, as well as gain better control at the arc to improve safety and productivity.
Walking back and forth to a vehicle to tweak an engine-driven welder/generator’s control panel takes time. Remote control devices increase productivity by putting the ability to make changes in the palm of the operator’s hand.
To stay competitive, more shops face the challenges of welding many different types of materials. To reduce setup times and help their operators produce high-quality welds, they must move beyond basic options and invest in advanced capabilities that can have a big impact on the bottom line.
The CD-V series includes built-in peak current indication for immediate weld fire confirmation; the TL-V weld heads complement the new power supplies.
Each solution from Yaskawa Motoman is designed for optimizing small- to medium-size part production for medium volume fabrication.
PM aluminum tubing can be located closer to the welding process than laminated tubing, creating a more efficient pneumatic setup.
