Pulse duty cycle
% Pulse is the ratio between set current and background current in a pulse cycle. In
order to control the energy of the arc and the size of the weld pool, pulse duty cycle is
adjustable by setting the percentage of the set current in a pulse cycle.
For example: If the pulse duty cycle is set to 50%, the time of the set current and the
background current will be distributed equally in the pulse cycle. If the pulse duty
cycle is set to 90%, the time of the set current will be 90% of the pulse cycle and the
background current will only be 10%.
Pulse frequency
The amount of pulse cycles in a time period. The higher the frequency, the more
pulse cycles per time period. When the pulse frequency is set low, the weld pool will
have time to partially solidify between each pulse. If the frequency is set high, a more
focused arc can be obtained.
Remote current
This is used to set the current for the foot pedal or remote control device.
In DC TIG mode, the minimum remote current is set by initial current and the maximum remote current
is limited by local set current. For example, in local mode set the "initial current" to 50 A and set the
"set current" to 200 A then switch to remote mode. The current range in remote mode is set from 50 A
to 200 A. the initial current (minimum current in remote mode) can be set on local mode and remote
mode but the set current (maximum current in remote mode) only can be set in local mode.
In Pulse TIG mode, the ratio between background and set current are the same as in local mode. For
example, if in local mode, the background current is set to 50 A, the set current is set to 100 A, and the
ratio is 0.5. Adjusting the set current or background current in remote mode, the ratio will keep the
same. By adjusting either of them, the other one will change accordingly.
