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.
Five Best Practices for Multi-Material Welding in Manufacturing
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.

When competing for time-critical jobs, saving even a few minutes with each changeover can make a significant difference and reduce operator exposure to trip and fall hazards. Investing in technology that allows welders to easily change processes with the push of a button at the weld joint can save substantial time, increase weld quality and improve operator safety.
Being nimble to meet project timelines is important to Sigma Thermal. Take a closer look at how their investments in new pipe welding equipment and technologies increased their productivity while keeping quality at the forefront.
Do you need faster travel speeds, reduced spatter levels and improved control over arc starts to boost efficiencies or improve your MIG weld quality? With some training and a little practice, pulsed MIG welding can drive the improvements you need. Here are some factors to consider whether it is a good alternative for your operation.
The need to weld many different material types and use different welding processes is increasing on the jobsite and in the shop. The ability to weld most any material – anywhere – with one lightweight, portable welding system that delivers industrial-level output can provide significant benefits for productivity, efficiency, and profitability.
Thermal Dynamics Automation’s new QuickPierce function speeds the piercing time on 400-amp cutting systems. Their cost calculator demonstrates long-range savings you can realize, thanks to improvements that extend the life of 400-amp consumables.
Four Magnum PRO Curve HDE semiautomatic welding guns from Lincoln Electric provide the best of both worlds: They deliver the highest duty cycle in their class and maximize operator comfort with a new ergonomic design.
Lincoln Electric’s Dual Maverick 200/200X is two welders powered by one diesel engine with two outputs, allowing two or more welders to work at the same time. Output remains steady even during arc stops and starts in dual mode.
