VANTAGE

520 SD
REMOTE CONTROL
The VANTAGE
®
520 SD is equipped with a 12-pin and a 14-pin
connector. To enable remote control capabilities, the
LOCAL/REMOTE switch must be in the REMOTE position.
For the DOWNHILL PIPE or CC-STICK weld mode selector switch
positions, remote setting of the preset arc current is set through the 12
pin connector or the 14 pin connector depending on the setup menu
setting (12 pin connector is the factory default setting). The OUTPUT
CONTROL knob is used to set the maximum arc current preset range
for the remote input. The left display will show the arc current preset.
For the TOUCH START TIG weld mode selector switch position,
remote setting of the preset arc current is set through the 12 pin con-
nector (typically using a foot Amptrol). The OUTPUT CONTROL knob is
used to set the maximum arc current preset range for the remote
input. The left display will show the maximum setting for the arc
current preset range as set by the OUTPUT CONTROL knob.
EXAMPLE: When the OUTPUT CONTROL on the welder is set to
200 amps, the arc current preset range on the remote control will
preset over the range from minimum to 200 amps, rather than the
full minimum to maximum preset arc current range. Any preset
arc current range that is less than the full range provides finer arc
current preset resolution for more fine tuning of the output.
For the ARC GOUGING weld mode selector switch position, remote set-
ting of the preset arc current is set through the 12 pin connector. The
remote input sets the arc current preset over the full range from mini-
mum to maximum. The left display will show the arc current preset.
For operation with a control cable wire feeder:
With the CV-WIRE weld mode selector switch position and the
WELD TERMINALS ON switch in the REMOTE position, remote
setting of the preset arc voltage is set through the 14 pin connec-
tor. The remote input sets the arc voltage preset range from
10.0V to 45.0V. The right display will show the arc voltage preset.
For operation with an across the arc wire feeder (for example,
an LN-25 PRO):
With the CV-WIRE weld mode selector switch position and the
WELD TERMINALS ON switch in the ON position, remote setting
of the preset arc voltage is set through the 12 pin connector. The
remote input sets the arc voltage preset range from 10.0V to
45.0V. The right display will show the arc voltage preset.
For the ARCLINK weld mode selector switch position, remote
capability is possible only with an ArcLink compatible digital
remote control through the 12 pin connector.
NOTE: To connect accessories with a 6 pin connector, use the
included 12-pin to 6-pin adaptor (K2909-1).

WELDING TERMINALS
®
The VANTAGE
520 SD is equipped with a toggle switch for selecting "hot"
welding terminals when in the "WELD TERMINALS ON" position or "cold"
welding terminals when in the "REMOTELY CONTROLLED" position. When in
ArcLink, the output of the weld terminals is controlled by the mode selected.
WELDING OUTPUT CABLES
With the engine off, route the electrode and work cables through the
strain relief bracket provided on the front of the base and connect to the
terminals provided. These connections should be checked periodically
and tightened if necessary.
Listed in Table A.2 are copper cable sizes recommended for the rated cur-
rent and duty cycle. Lengths stipulated are the distance from the welder to
work and back to the welder again. Cable sizes are increased for greater
lengths primarily for the purpose of minimizing cable voltage drop.

** Tabled values are for operation at ambient temperatures of 104°F (40°C) and below. Applications above
104°F (40°C) may require cables larger than recommended, or cables rated higher than 167°F (75°C).
PULSE WELDING
When pulse welding, always use 4/0 cable. The cables must be sized
based upon the peak current of the pulse waveform, not the average
current. Do not coil the electrode or work cable. Limit the combined
length of the electrode and work cable to 60 feet. Undersized cables,
coiled cables and long lengths all increase cable inductance and
lower pulse welding performance.
CABLE INSTALLATION
Install the welding cables to your VANTAGE
1. The engine must be OFF to install welding cables.
2. Remove the flanged nuts from the output terminals.
3. Connect the electrode holder and work cables to the weld output terminals.
The terminals are identified on the case front.
4. Tighten the flanged nuts securely.
5. Be certain that the metal piece you are welding (the "work") is properly
connected to the work clamp and cable.
6. Check and tighten the connections periodically.
