1) Stabilizing output voltage
Feedback control of output current and voltage is used to stabilize
output with input voltage change.
For stabilizing output voltage in the case of insufficient or excessive
output occurs compared with setting value, changing duty cycle(phase
angle) enables voltage to be constant and results in stable output.
2) Stabilizing Wire feed rate
Controlling wire feeding in a constant speed with input power change keeps
arc stability and output current constantly.
3. Special Features of ProPAC Model
3.1 Output power stability with input power voltage change

( WFS stability with cable length)
▣ Stabilizing feed rate with long cable usage
Change of control cable length and/or load
current of feed motor can lead voltage
drop occurs in the control cable and
resulting in feed rate drops.
▣ Preventing welding wire slipping
*. Responding time and life
1) Relay : Responding time -- 30mS, Contact point life -- 100,000 times
2) MOS-FET: Responding time -- 0.2 ㎲, Contact point life -- Semi-permanent
*. Calculation of wire slipping length
Condition)1.2mm 350A WFR 15.8m/min
1) Relay : Responding time - 30mS � max. 7.8mm
2) MOS-FET: Responding time - 0.2 ㎲ � 0.000005mm
In order to prevent wire slipping after
welding, fast responding (150,000 times
faster than common relay) MOS-FET is used
to stop wire in the shortest time and can
be used semi-permanently.

� voltage is compensated for the amount
of voltage drop and the range of feed rate
change is minimized, and finally output
current will be stabled.
3. Special Features of ProPAC Model
3.2 Stability of Wire Feed Speed
-28-
Long cable usage can cause malfunction of welder or unstable output due to magnetic
field(Noise) around Single Cable. However, ProPAC Model is designed not to be affected by
Noise with 120m Single Cable, therefore stable welding can be performed.
◇ Calculation of output power in shipyard
1) Welding Condition : FCW(1.4mm) 450A
-.Suitable welding voltage: 0.05 × 450A + 18V = 40V
2) Voltage drop with cable length
Shipyard condition
-. Single Cable 60sq 50m + Extension Feeder 30m : Total 80m
-. Voltage drop on cable : 12V
3) welding power demand : 52V
※ Since it is maximum output power condition, input voltage
drop will cause output voltage drop
※Think about…
3.3 Stable welding power with 120m long cable length
3. Special Features of ProPAC Model
▣ High power welding in shipyard
▣ Stable welding with 120m long cable usage
Since ProPAC 600 model has a higher power, 600A 52V (100% Duty Cycle), compared to
competitor, long cable can be used without the lack of power.
