PORTABLE SOLUTIONS
of across the arc models and adding a control cable, while enjoying all the benefits. These include productivity gains - work faster, reduce movement, and minimise rework; safety - reduce the chance for injury by reducing the number of cables underfoot; and quality - meet WPS specifications more easily with greater operator control.
True Voltage As is common in many outdoor welding applications including structural steel, shipbuilding, offshore, and so on the operator can be located hundreds of feet away from the power source. All that cable can create a difference in voltage, or voltage drop, between the power source and the weld. For example, 24 volts is set on the welding power source. However, due to electrical resistance through long
cables, only 20 volts are actually available at the arc. This would result in a cold weld. Lincoln Electric’s True Voltage
Technology (TVT) calculates this drop and gives you the true voltage you set by adjusting the power source to compensate for the voltage drop. In the example above, 24V is preset at the LN-25X. TVT senses there is a 4 volt drop due to long weld cables and compensates by increasing the welder output to 28V. The result is the desired 24 volts available at the welding arc.
CrossLinc Technology Enabled Equipment CrossLinc technology compatible feeders and power sources from Lincoln Electric carry an X in their
