Self Shielded Flux-Cored Wire vs. 7018

Self Shielded Flux-Cored Wire vs. 7018

It’s All About Productivity Yes, the stick process still has its place in the welding world.  But for structural applications where 7018 is still ubiquitous, it’s highly inefficient. 7018 is 65% efficient, meaning 35% of what you buy doesn’t go into the weld. It...
Wire Feeders: Voltage Sensing Wire Feeder

Wire Feeders: Voltage Sensing Wire Feeder

A voltage sensing,  or “across-the arc” wire feeder is very popular and very misunderstood, so let’s start from the beginning. What is a feeder? What is it?  A feeder, usually in a suitcase or pelican box, that can run on a constant voltage (CV) power...
Constant Voltage for Wire Processes

Constant Voltage for Wire Processes

Not All Constant Voltage is Equal Constant Voltage (CV) is the most common output for wire processes, but both Miller and Lincoln sometimes use the term loosely. The Miller Bobcat volt-amp curve (Figure 1), for example, looks nothing like a traditional CONSTANT...
All Position Welding Productivity Maximized

All Position Welding Productivity Maximized

All Position Welding Productivity with Dual Wire Feeders Dual wire feeders have never really caught fire, in part, because fabricators see the price and don’t see the justification. Connected to ROI, there may be some misunderstanding with regard to in-position...
Pulsed MIG: To Pulse or not to Pulse?

Pulsed MIG: To Pulse or not to Pulse?

The Many Advantages of Pulsed MIG In the coming years, the strongest companies will prevail. Those companies will likely have a strong history of cost reduction by way of improved efficiencies and output. Manufacturers and fabricators that rely on labor-intensive arcs...
Electrode Diameter & Current Density

Electrode Diameter & Current Density

Myth Exposed: Electrode Diameter and Current Density Selecting the correct wire diameter for MIG, Submerged Arc (SAW), and Flux Cored Arc (FCAW) welding can be a challenge. That is because there are two (often misunderstood) statements associated with electrode...
