Automatic changes between wire and gas can be accomplished by placing two feeders equipped with a switching unit onto one Yaskawa Electric robot and one digital welder. Through the use of a motor equipped with an encoder, the setting of the amount of wire retraction or feeding is made possible. Setting the amount of retraction and feeding to the same values will result in a constant length of wire protrusion, allowing you to immediately start welding.

Features

• High-speed automatic wire changes
  High-speed automatic changes between equal-diameter and unequal-diameter wires (*1) are made possible. At the same time, two types of shielding gases can be changed.
• Space-savings around the arm
  A space-saving configuration has been accomplished through the use of a newly developed special cable and a dedicated torch.
• A single digital welder supports various types of welding It can change between short-circuiting and pulse welding of course; it also supports aluminum and SUS welding. Signals from the robot controller enable changes in wires and welding conditions.
  (*1: APC is required for unequal-diameter wire changes.)
