Example of hotstart function
Function:
during the specified hot-current time (Hti),
the welding current I
1
is increased to the
HotStart current HCU.
To activate the hotstart function, the HotS -
tart current HCU must be > 100.
Settings examples:
HCU = 100
The HotStart current corresponds to the set welding current I
1
.
The hotstart function is not activated.
HCU = 170
The HotStart current is 70% higher than the set welding current I
1
.
The hotstart function is activated.
HCU = 200
The HotStart current is twice the set welding current I
1
.
The hotstart function is activated, the HotStart current is at its maximum.
HCU = 2 x I
1
Anti-stick func -
tion
As the arc becomes shorter, the welding voltage may drop so far that the rod electrode will
tend to stick. This may also cause the rod electrode to burn out.
Electrode burn-out is prevented by activating the anti-stick function. If the rod electrode be -
gins to stick, the power source immediately switches the welding current off. After the rod
electrode has been detached from the workpiece, the welding process can be continued
without any problems.
The anti-stick function can be activated and deactivated in the "Set-up menu - level 2" sec -
tion.
