Cooling unit monitoring
Time from when the flow sensor is triggered until the "no | H2O" service code is output.
For example, if there are air bubbles in the cooling system, the cooling unit will not cut
out until the end of this preset time.
Unit s
Setting range 5 - 25
Factory setting 10
IMPORTANT! Every time the power source is switched on, the cooling unit carries out
a test run for 180 seconds.
HF ignition
High frequency ignition: Time interval between the HF pulses
Unit s
Setting range 0.01 - 0.4 / OFF / EHF (start with external arc starters, e.g.
plasma welding)
Factory setting 0.01
NOTE!
If there are problems with sensitive equipment in the immediate vicinity, increase
the HF ignition parameter to a maximum of 0.4 s.
The special HF ignition indicator lights up on the control panel provided that a value
has been specified for the HF ignition parameter.
If the "HF ignition" setup parameter is set to "OFF", no high frequency ignition takes
place at the start of welding. In this case, welding starts with touchdown ignition.
CAUTION!
Risk of injury due to shock caused by electric shock
Although Fronius devices comply with all relevant standards, high-frequency ignition
can transmit a harmless but noticeable electric shock under certain circumstances.
▶
Use prescribed protective clothing, especially gloves!
▶
Only use suitable, completely intact and undamaged TIG hosepacks!
▶
Do not work in damp or wet environments!
▶
Take special care when working on scaffolding, work platforms, in forced posi-
tions (out-of-position welding), in tight, difficult to access or exposed areas!
rPI ignition
Reversed polarity ignition
Unit -
Setting range ON / OFF
Factory setting OFF
IMPORTANT! The rPI ignition function
- is only available on the MagicWave power source
- is not recommended for welding light-gauge sheets
