3.7.5 Fast information buttons
There are two shortcut buttons on the control panel that use can use to display important
information on screen.
• F1 (CHANNEL INFO) button displays the basic data recorded to the selected channel.
• F3 (WF#) displays active and selected wire feed unit, and allows a new wire feed unig
selection. KempArc Pulse TCS allows up to 7 wire feed units to be connected to one
power source.
NOTE! Only one wire feed unit can be active at any one time and must be selected before it will
operate.
4. ABOUT TANDEM MIG/MAG WELDING
4.1 WHAT IS TANDEM MIG/MAG WELDING?
Tandem MIG/MAG welding is a high speed double-wire welding process, where two filler
wires are fed simultaneously into the weld pool. Both filler wires are controlled by their own
power sources. The welding gun is equipped with two contact tips, which are electrically
insulated from each other. This allows filler wires to have different electrical potentials.
Tandem welding has always been considered a productive yet challenging welding process,
where it is difficult to find the right parameter settings to reach a good balance between fast
welding speed and welding accuracy.
In KempArc Pulse TCS, however, the two filler wires are controlled by Kemppi's tandem control
system (TCS), which allows independent and very accurate control of the welding wires. The
operation of each filler wire is adjusted dynamically during the welding according to various
control parameters and the weld pool shape. This makes it possible to achieve a fast and easy
system setup and exceptionally high welding productivity.
