Press Welder: ERE Spot Projection Welders
Specifications | Options | Drawings
• Single Phase • Press Type
One of our most rugged welders, the ERE, RWMA Size 2, gives you simplified versatility and dependability, allowing you to switch from spot to projection welding with an absolute minimum of changeover time. Taylor-Winfield quality is reflected throughout. In addition, we stock a complete inventory of replacement parts and in-stock components can be shipped within 24 hours of order receipt. When you buy from Taylor-Winfield, you get sound technical advice, competent service and continued performance backed by single source responsibility.
