Calibrating of the source in MMA, ARC GOUGING and TIG mode
-
Set the current setting to the minimum value.
-
No-load state voltage of the source should equal 56V +/- 10%.
-
Using the RP 5 assembly potentiometer set the load current for the output voltage of
approx. 20.5V to the value of approx. 20A.
-
Set the current setting to the maximum value.
-
Using the RP4 potentiometer located on the CH21 board set the maximum value of the
welding current: 400A/36V for ORIGOArc 410, 650A/44V for ORIGOArc 650 and
800A/44V for ORIGOArc 810.
Checking the HOT START function
-
Set the current setting to 100A, while the ARC FORCE and HOT START knobs to the
minimum value.
-
Switch on the 0.24
Ω
load on the resistor (100A) in a stepwise manner. A stepwise
increase of the welding current up to 100A should take place.
-
Set the HOT START potentiometer to the maximum position. Switch on the 0.24
Ω
load on
the resistor (100A) in a stepwise manner. Value of the welding current increased by 50%
<147A, 153A> should be included in the time interval <2.4s, 2.6s> and then fall to the
value of 100A.
Checking the ARC FORCE function
-
Set the current setting to 50A, while the ARC FORCE knob to the maximum value and the
HOT START knob to the minimum.
-
Increase the source load. Below the threshold of 18.7V, the welding current value should
increase to the value included in the range of <174A,180A>.
-
Set the ARC FORCE knob to the minimum value, the value of the output current should
fall to the set value, i.e. 50A.
Checking the ANTISTICK function
Checking the ANTISTICK function in MMA mode
-
Switch the source to MMA mode and set the welding current to the value of 50A. Set HOT
START and ARC FORCE knobs to the minimum value.
-
Load the source. Below the threshold of 4.5V, the current should fall to the value of 10A
with the delay within the range of <1.7s, 1.9s>. This value should be set using the RP6
potentiometer.
