CONVERTING TO A POWER WAVE PROCEDURE

An easy approach to making a conversion to a Power Wave AC/DC 1000™ procedure is to use this table as a general guide and follow these steps:

1.Start with the existing variable voltage DC positive procedure as the reference procedure.

2.Move to AC balanced square wave mode and use the reference travel speed and voltage.

3.Adjust frequency from 30 to 90 Hz. (stop if the current value begins to drop).

4.Shift the AC balance to 25%,

a.Increase voltage 2-3 volts,

b.Increase travel speed 1.2 times reference value.

5.Add 5 to 10% negative (minus) offset,

a.Increase voltage an additional 1-2 volts,

b.Raise travel speed to 1.3 times reference speed.

This will yield a good starting point for converting a DC+ fillet welding procedure. Fine tuning these steps will yield the maximum increase with equal or improved weld appearance.

Easy Welding Procedure Setup

The Power Wave AC/DC 1000™ system is the easiest system ever produced when it comes to changing from one welding procedure to another.

No need to move (change) welding cables even when changing polarity or changing from constant current to constant voltage.

No need to internally reconnect power carrying taps or bus bars, hence, in many instances no need for a maintenance electrician.

Control all output functions on the control panel.

Fully supported by Lincoln’s Power Wave Submerged Arc Utilities software where demanding applications require activity reporting or even remote procedure verification (see Nextweld NX3.20 brochure).The heart of the system is the Power Wave AC/DC 1000™ featuring:

Balanced input line-draw even when welding with AC.

High 86% electrical efficiency contributes to keeping energy charges low.

95% power factor assures minimizing excess ampere draw from the supply lines.

Continuous output rating 1000 amperes assures the system is ready-to-go full time.
