DC TIG Pulse Operation with Remote Current Controller Connected:
EMP 205 machine supports following different Remote Current Controllers supplied by ESAB.
1.
Foot Pedal
2.
Remote Hand Pendant
3.
Remote Thumb Controller (separate or as part of TIG Torch assembly)
When Remote controller is connected to EMP 205 machine using 8-pin receptacle on the front panel, the background
current calculations are different than that with regular TIG torch with trigger. Without Remote controller the background
current value is the set percentage times the user set current but with Remote controller it is the set percentage times the
Remote controller set current.
Example:
Basic Mode:
If user sets current as
I
peak
(A) = 100
The default settings for other parameters in basic mode are
Background (%) = 50
Peak Time (%) = 50
Hz/PPS (Pulses Per Second) = 2.0
I
min
(A) = 5
The calculated value of
I
back
(A) = 50A (I
peak
* 50% = 100 * 0.5)
This means if the Remote controller set to all the way then,
I
peak
= 100A
I
back
= 50A
but if user sets the Remote controller to half way then,
I
peak
= 50A
I
back
= 25A
and if user sets the Remote controller to three-fourth way then,
I
peak
= 75A
I
back
= 37A
