Kemppi master 5001 Operation Instructions Manual page 10

Use of arc powered wire feeder
Master 5001 can be connected as power source to an arc powered wire feeder. In that case set
switch S21 of control panel to centre position. Power source operates then on constant voltage
characteristic curves (cv), which provides the best welding properties for arc powered units. Set
voltage is set with potentiometer or with remote control unit, if installed.
Scratch-start/contact TIG
Master 5001 can be used in TIG welding by switching the jumpers of control card to position TIG
(see jumper settings below). TIG welding is selected by setting switch S21 to centre position. Set
value of TIG is selected with control panel or with remote control unit, if installed. When TIG
electrode touches work piece welding current is on so called pilot current, which is 25 A. Current
is raised or reduced to actual welding current by pulling the electrode away from work piece. Note
that there is always voltage in the electrode when unit is set on TIG welding.
