EPE Spot Projection Welders

• Single Phase
• Press Type EPE, RWMA Size 3 (Sizes 1, 1-A & 5) gives you simplified versatility and dependability.
• It allows you to switch from spot welding 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.

EPE
  • A hardened and ground steel ram, guided by eight anti friction rollers to insure positive alignment, minimize deflection and reduce friction.

  • Spot welders available in 18, 24 and 36 inch throat depths, Projection welders in 12, 18 and 30″.
  • Four inch ram stroke.
  • Air pressure regulators and gauges (with force chart) and air line lubricator.
  • Speed control valves to control ram movement up and down.
  • Air exhaust muffler.
  • Three transformer sizes: 150, 200, 230, 250, and 400 kva operating on either 230 or 460 volts, 60 Hz (not both).
  • Built-in 8 step tap switch.
  • Single stage foot switch.
  • Style #1 upper and lower T-slotted platens. Style #5 upper (2-3/4″ dia) and lower (3″ dia) and lower (3-1/4″ dia at front tapered to 5″ dia at rear) solid round horns with electrodes and holders.
  • Lower horn brace (Only on Style #5 welders of 36″ spot throat depth or more).
