117A
90A
Example of HotStart function
Mode of operation:
The welding current is raised to a specific value for 1.5 seconds. This value is around 30%
higher than the set welding current
Example: 90 A was set on the adjuster.
The HotStart current is 90 A + 30% = 117 A
IMPORTANT!
If the welding current is set to 192 A or higher, the HotStart current is limited to 250
A.
SoftStart function
The SoftStart function is intended for basic electrodes. Ignition takes place at a low welding
(used with basic current. Once the arc is stable, the welding current continues to rise until it reaches the
process) welding current command value.

Example of SoftStart function
Anti-stick func- As the arc becomes shorter, the welding voltage may drop so far that the rod electrode will
tion tend to stick.
The anti-stick function prevents the electrode from burning out. If the rod electrode begins
to stick, the power source switches the welding current off after 1 second. After the rod
electrode has been lifted off the workpiece, the welding operation can be continued without
difficulty.

Benefits:
- Improved ignition properties, even
when using electrodes with poor igniti-
on properties
- Better fusion of the base material du-
ring the start-up phase, meaning fewer
cold-shut defects
- Largely prevents slag inclusions
Benefits:
- Improved ignition properties for elec-
trodes that ignite at low welding cur-
rents
- Largely prevents slag inclusions
- Reduces welding spatter
