Andy Monk of Bernard Welding Equipment shows how to greatly reduce downtime spent changing contact tips and troubleshooting weld defects by carefully choosing MIG gun consumables and carrying out a regular inspection and maintenance schedule.

Our three-part series continues with landscape design fabricator Kris Kesler of Bobé Water & Fire Features combining high-tech computer modeling with time-tested techniques to engineer a freestanding waterfall fireplace.

To produce a clean, slag-free weld without having to continually stop welding to replace the electrode in your specific application, it helps to understand the role of shielding gas, the different shielding gases available and their unique properties. In this primer, Andy Monk of Bernard Welding Equipment explains each of these.

Lufer Industria is using sub-harmonic vibration technology to reduce part manufacturing process costs by more than 90 percent and stress relieving time by 97.5 percent.

This bridge fabricator relied on a solid electrode in its submerged arc welding process until a composite metal-cored electrode improved its welding travel speed by 40 percent a sub-arc bridge fabrication application.

On display: New tools that could help reduce your costs and make your welding operations more competitive.

For welding applications that demand excellent weld penetration, high productivity rates and good low temperature impact strength, this general fabrication welding wire for mild or low alloy steels can be used in all positions with either 100 percent CO2 or a 75 percent Ar/25 percent CO2 shielding gas mixture.

This showcase of new electrodes and filler metals displays the latest advancements that could make your welding processes more competitive.

Leave the generator and extension cords behind. The Trek 180 from Hobart Welding Products (Appleton, WI) is a portable MIG welding system that operates off its self-contained battery or 115V power, welds 24 ga up to ¼ in mild steel in a single pass, and recharges off an automotive power inverter or 115V receptacle.
