Waveform Control Technology

Just as computer companies recognize the importance of providing their customers with multi-functional equipment, Lincoln Electric realizes that our customers want the power to choose what fits them best. As companies broaden their product offerings, this desire has turned into necessity.

In the past, different equipment has been required for different welds. Customers often needed several models of welding equipment to perform a variety of welding procedures.

Waveform Control Technology revolutionizes the way welding equipment is chosen. Waveform Control Technology welding systems support 8 processes, over 80 weld procedures, and the option to fine-tune or develop new welding programs. Waveform Control Technology is available in semi-automatic, hard automation, or robotic systems. We’ve put the power of choice back into the hands of the operators. Choose wisely. Choose Waveform Control Technology.

SIMPLIFIED PROCESS SELECTION

Metal transfer modes may be controlled to extend the stable operating range of the welding process.

ADAPTABILITY

Shapes the arc using computer software. A single machine can quickly and easily adapt to:

• A wide range of applications

• Varying materials specifications

• Varied weld positions

• Appearance requirements

WELD QUALITY

Optimized metal transfer reduces spatter and improves arc stability.

PRODUCTIVITY

Higher deposition rates are possible at heat input equal to or less than traditional CV processes.

CUSTOMIZABLE

Output parameters may be adjusted for given welding waveform conditions and joint design to meet weld specifications and production rates.

Alterations to the waveform can be made during the weld,

using software created by Lincoln Electric.

The future of welding is here.

What

is Waveform Control?

Waveform Control Technology is the ability to customize waveform output. It is the ability to choose a weld program from a pre-defined set of programs, and to manipulate the parameters of that program to best fit your application.

Lincoln Electric strives to understand the customer’s needs in order to make the job easier. That is why Waveform Control Technology was designed: to empower the people who use the equipment, our customers.

Waveform Control Technology allows the user to choose from a library of pre-programmed weld “modes” that have been developed by expert welders. Then, Waveform Control Technology offers the opportunity to change those

values, within a programmed range, to find the combination of wire feed speed, voltage, current, and arc control that the application requires.

But Lincoln has even taken it one step further. Waveform Control Technology also provides the ability

to use a single source to perform Stick, TIG, MIG/MAG, Flux-cored, and Submerged Arc welding procedures. With a Waveform Control Technology product, the days of configuring different systems to make different welds are over.

How

Waveform Control Works

There are many physical forces that affect the welding arc and the transfer of metal from the electrode to the weld puddle. Surface tension, magnetic, and aerodynamic forces are the most significant. The welding current directly affects the magnetic and aerodynamic forces in the welding arc. The welding current and surface tension forces can be balanced to control metal transfer within the arc.

High-speed electronics monitor the electrical signals from the welding arc and make appropriate changes to the current waveform. The electronics must be fast, accurate, and rugged to control the arc and withstand the harsh welding environment.

Waveform Control Weld Programs

Equipped with our most up-to-date welding programs, Waveform Control Technology systems suit the majority of welding applications. The flexibility of choosing from a variety of welding programs not only increases productivity, but also promotes consistently high-quality welds.

Power MIG 300, Invertec V350-PRO, and Power Wave welding systems are all Waveform Control Technology systems. They come fully loaded with a software library that is accessible from the user interface. With the Power Wave, software programming enables the flexibility of uploading the weld programs to a PC, or Ethernet and DeviceNet applications (hard automation).

The programs listed in the following tables were developed by Lincoln Electric.* It is important to note that, although we attempted to provide a broad operating window for each program, they were developed using Lincoln consumables. Therefore, Lincoln Electric cannot guarantee that these procedures will operate at optimum level when used with non-Lincoln Electric electrodes.

A mode number is assigned to each weld program. The following lists include the most commonly used weld programs, and are grouped according to material. Find the mode number for your material and program specifications, then select that mode number on the welding system user interface.
