Using Metal-Cored Wire with Pulsed MIG to Weld Galvanized Steel

High strength galvanized steel is an excellent material to help automotive manufacturers build lighter-weight vehicles, but it can present some challenges that make it difficult to weld.

Industry Standards Are Evolving Faster Than Ever

Fuel economy mandates are dictating significant design changes to new vehicles and trailers. To comply with these changes, shops must learn new techniques while training technicians to weld aluminum in addition to steel. To reduce the already expensive overhead costs auto body and repair facilities endure, it is critical that the welding machine provides versatility and timesaving features.
For auto body shops or tractor repair facilities to effectively keep up with the new demands being driven by fuel economy mandates and remain profitable, they must invest in easy to use equipment that is capable of welding both steel and aluminum.

Ways to Get the Most Out of Your MIG Gun Consumables

Nozzles should be cleaned at least every other welding cycle in a robotic welding operation to prevent spatter buildup that can lead to poor gas shielding or cause short-circuiting between the contact tip and nozzle. Heavy-duty consumables are recommended for high-temperature robotic welding applications. If the robotic welding operation calls for a heavy-duty retaining head, pair it with heavy-duty contact tips. Always check the torques of the body tube and end fittings regularly to prevent loose fitting cables that can cause overheating and lead the robotic MIG gun to prematurely fail.
Here are a few of the best practices that every welding operator should know when it comes to choosing and maintaining nozzles, contact tips, retaining heads and gas diffusers, and cable.

New Arc Process for More Efficient Welding

A new algorithm uses the high processing power, large memory, extremely fast system bus and highly dynamic wire feed speed of the latest MIG/MAG power source platform to ensure an extremely stable arc with minimal spatter.

Field of Dreams

High Tech Welding has gained 25 to 30 percent in productivity in its field repairs since it began using the Multimatic 200 a year ago. The portability and multiprocess capabilities of the unit are at the heart of those benefits.
Take a look at how Wisconsin fabricator High Tech Welding uses a portable all-in-one multiprocess power source to gain versatility and increase their welding productivity by 25 to 30 percent on field repair and fabrication jobs.

What You Must Know About Robotic Welding

Lloyd Steed of Tregaskiss identifies the key factors that must be understood to manage a profitable and productive robotic welding operation that really gains a competitive edge and makes the most out of its investment.

Ergonomic Wand, Carbon Fiber Brushes for MIG and TIG Weld Cleaning

The Surfox Wand is articulated to allow a greater range of motion. 
It is compatible with the company’s carbon fiber brushes with segmented sleeves that are used for cleaning MIG welds. The segmented sleeves can be trimmed away with a pair of long nose pliers, up to three times,to get more life out of each brush. The triangular brush is used for cleaning larger surface areas, whereas the cylindrical sleeve brush is used for tight corners and spot welds. The new wand also remains compatible with tungsten inserts and high conductivity cleaning pads.
The Surfox Wand from Walter Surface Technologies features a quick-change system for accessories to clean larger and hard-to-reach areas at an optimal rate.

Welding Showcase

With the 9100XXi ADF from 3M, welders have a new level of visibility and control. They’ll have a vibrant, crisper view of the workpiece with a greater field of colors. With these improved optics, welders may experience better control of the weld puddle and more precise set-up and finishing operations. It also may make it easier to distinguish the colored control panels on welding machines.
Here is some of the latest welding equipment and accessories to help your shop become more competitive.

Multi-Process Welding in a Smaller Package

Ideal for withstanding harsh environments, the compact Dimension 650 multi-process welder from Miller Electric offers an unbeatable combination of durability, output, efficiency and capability with exclusive protection against “dirty power” commonly found on jobs to prevent power fluctuations from affecting performance or reliability.
The Dimension 650 from Miller Electric provides both power-intensive output for heavy welding and carbon-arc gouging, as well precision arc characteristics designed for thin-metal welding.
