NOTE: Slope function operates with a Remote ON/OFF device only.
1) To start Slope sequence Close remote switch contacts. Once the welding arc is established the
Power Source will maintain initial current setting as long as the remote switch contacts are
closed.
a) In the HF TIG mode, after Preflow time High Frequency is present at the torch. When the
torch is positioned close to the work the welding current will transfer to the work and
establish the arc at the initial current setting.
b) In the Lift TIG mode, after preflow time Lift Start current is present at the torch. When the
electrode is touched to the work and lifted off, the welding arc is established at the initial
current setting.
2) Open Remote Switch – current increases to weld current. Once welding arc has reached weld
current the power source will maintain weld current as long as the remote switch contacts are
open.
3) Close Remote Switch – Welding current decreases to final current setting. Once final welding
current is reached the power source will maintain final current setting as long as the remote
switch contacts are closed.
4) Open Remote Switch – Welding arc stops and post flow begins.
6.02.02 Slope Mode with repeat sequence
The repeat function is operated during the down slope cycle of the Slope Sequence and is active
through the down slope period only. During the down slope period by opening the Remote Switch
contacts the current will increase back to weld current. Within the Down Slope period the repeat
function can operated as many times as desired. To continue slope cycle and end slope sequence
close remote switch contacts and allow weld current to reach final current setting. Once final current
setting is reached opening the Remote Switch again will turn off the welding arc and post flow
begins.
