Rising the Bar for Efficiency
Owner Mike Urena knows that in roofing, time and quality go hand in hand. His focus as a business leader is clear: make work easier, faster, and more effective for his crews.
“As a business owner, we always look for ways to improve efficiency,” Mike says. “Whenever you can find a way to do things faster, that’s what you do.”
Armoured Exteriors had built its reputation on residential and smaller commercial projects — restaurants, sunrooms, and similar jobs where hand welders were ideal. But as the company expanded into larger commercial roofs, the team realized it needed a solution built for scale.
A Smarter Investment for Bigger Jobs
That’s where the Leister VARIMAT 500 came in. With more open roof area to weld, relying solely on hand tools was no longer practical. The automatic welder quickly proved to be a game-changer.
“The VARIMAT 500 has been a key part of allowing us to complete roofs faster and more efficiently,” Mike explains. “It’s a real asset to our company.” Beyond speed and performance, the tool also improved crew well-being. By reducing the physical strain of manual welding, it’s helped make large-scale projects safer and more manageable.
Simply to Learn, Easy to Trust
Leister provided hands-on training, ensuring every technician knew how to operate the VARIMAT 500. For some, it was their first experience with an automatic welder — and the reaction was instant.
“They were excited to see the huge difference between hand welding and automatic welding,” Mike says. “The setup and testing process is straightforward, and performing test welds is quick and easy.”
