Manufacturer Sees 75% Less Spatter and Reduced Training Time With Deltaweld® Systems

Miller Deltaweld® and pulsed MIG

When the snow flies, snow removal crews must keep roads clear for emergency vehicles and other drivers. Henderson Products in Manchester, Iowa, plays a critical role in this process.

“We’ve got equipment in every state,” says Kevin Schueller, Henderson manufacturing manager. “Our motto is ‘keep America’s roads safe,’ so when we deliver a product, it needs to be the highest quality.”

A North American leader in the design, manufacture and upfit of multi-purpose equipment for heavy-duty work trucks that specialize in snow and ice control, Henderson aims to deliver reliable and durable equipment that runs every time it’s needed.

Founded more than 75 years ago, the company shifted from producing agricultural attachments to its current status as a leader in snow and ice removal equipment. They sell through independent dealers and directly to government agencies such as state DOTs. At their 175,000-square-foot facility in Manchester, Henderson manufactures a range of products, including dump bodies, snowplows, sand and salt spreaders, anti-ice systems and combination bodies for heavy-duty trucks.

“Our business is very customization driven,” Schueller says. “We pride ourselves on working with customers to provide whatever changes they want and whatever products suit them well. We’re a one-stop shop for turnkey packages.”

Due to the level of customization, Henderson doesn’t have many high-volume orders. This requires flexibility on the part of their welders and welding equipment.

“A lot of times when you look up and down our product lines, you see that everything is different,” says Welding Engineer Thomas Kenny. “Our machines and our welders have to be able to accommodate whatever material is thrown at them, whatever material thickness.”

The versatile machine that Henderson relies on to tackle any job? The Deltaweld® system and Intellx™ wire feeders. The system works on a wide range of materials and thicknesses while reducing post-weld cleanup and training time.

Flexibility for more jobs

Henderson completes fabrication, welding, painting and final assembly at the plant, but welding is a core competency. It’s important that the nearly 80 welders at the facility are producing the same high-quality parts. Normal manufacturing cycle time is a week to 10 days, and the parts are typically mild steel or stainless, ranging from 16 gauge to several inches.

“Having similar welding equipment and new technologies across the board really helps with keeping the quality high,” Kenny says.

As the facility replaces legacy equipment, Miller partners with them to choose welding power sources that best fit Henderson’s needs. The most critical need for Henderson is power sources that are easy to use, offer flexibility for welding different parts and materials, provide strong and stable arcs, and are adaptable for different input power. The facility has about 20 Deltaweld® 350 machines used for pulsed MIG welding.

“It’s really remarkable how easy the machine is to use and identify the correct settings,” Kenny says.

Saving time by reducing spatter

Post-weld cleanup is a time-consuming part of welding. Since switching to the Deltaweld® 350 and pulsed MIG, Henderson has realized a significant reduction in spatter during welding. This cuts the time spent on post-weld grinding and cleaning.

Kenny recalls training welders at another facility on the Deltaweld system. After a while, he stopped the welders to ask how much spatter they were seeing. The welders closely inspected every weld and found only one piece of spatter among all of them.

“It really does produce much less spatter,” Kenny says. “In my cost justifications, I calculate about a 75% reduction in spatter with the Deltaweld and pulsed MIG, and in some cases it’s more than that. When you take that across all of welding cells, that’s huge.”

Reduced training time for welders

Like with many manufacturers, it can be difficult for Henderson to find skilled welders. The company started its own training program with a local community college to train welders in-house. Some people enter the training program with a little welding experience, while others have none.

Using welding equipment that makes it easier for new welders to learn and train means Henderson can get them up to speed and into the production environment faster.

“The Deltaweld® 350s really help us during the training of new welders,” Kenny says. “I can shave a week off that training time because the machine is very adaptive and helps them learn how to weld and achieve a good weld faster.”

Samantha Fleming has been a welder at Henderson for several years. Her typical day involves different types of welds since her job is to repair broken equipment or parts that are under warranty for customers. She has to determine the best way to weld them, and that often involves changing between wires frequently.

The Intellx™ Elite Feeder provides information about the weld and parameter changes, helping her grow as a welder. It also saves her time in making adjustments because the machine confirms the correct ranges.

“It’s actually been teaching me a lot on mistakes I may have been making with settings,” Fleming says. “You turn the knob, and it shows you the diagram of what’s going on inside the weld. It’s foolproof. I really like it.”

Feeder display builds welding knowledge

The Elite feeder’s full-color LCD screen provides graphical information to the operator about what’s happening in the weld as they change settings. If the operator makes a change to wire feed speed settings, for example, the interface shows them if it’s out of the suggested range.

“The welders get so much information just by looking at the feeder interface. As they make adjustments, the screen shows what’s changing inside the weld,” Kenny says. “That’s imperative because I can talk with a welder until I’m blue in the face, but once they have that feeder showing them the information and they stare at it all day, it starts to sink in.”

That has resulted in a lot of newer welders seeking out Kenny for discussion about why certain changes make the weld react in a certain way. Even experienced welders can better understand details of the weld and how the weld is affected by changes they make.

“It really started driving the conversations to develop their knowledge of welding even further,” Kenny says. “It’s amazing how that feeder has helped me share information.”  

Wire feeder versatility for different materials

When Henderson welders switch from mild steel to stainless or from flat, horizontal welding to vertical welding, they typically need to adjust wire feed speed or other settings. Many parts welded at Henderson are large and hard to roll, so operators must adapt quickly and weld in other positions.

That’s where the Intellx Elite wire feeder comes in. The wire feeder provides eight customizable memory settings so operators can touch a button to switch parameters for a specific weld. Memory one could be set to run on 10-gauge steel in the horizontal position, and memory two could be set to run vertical down welds on stainless, for example.

“The beauty of the Elite feeder is it makes it really, really easy to make those adjustments,” Kenny says. “Rather than having to remember what settings are acceptable, operators can push a button and jump into a new part.”

One welding system for every need

Thanks to the Deltaweld® 350 system and Intellx™ wire feeders with pulsed MIG welding, Henderson Products reduced training time for new welders and improved productivity by drastically lowering the levels of spatter produced during welding. The system is a game-changing solution that delivers everything Henderson needs to be competitive and meet customer demands.

“They’re capable of doing everything we need them to do, and they provide us exactly what we want,” Kenny says. “Our efficiency and quality are very important to us. We view our units as very large billboards when they’re going down the road. People driving by will see our product, and we want the welds to look great.”
