TANDEM CRUISER™
A-2
GENERAL PHYSICAL DESCRIPTION
The Tandem Cruiser™ is a self propelled, modular
platform for performing submerged arc welds. A unique
tube and clamp design provides flexibility to mount the
feeding components in any position.
Wire is fed to the arc with proven wire drives. All of the
drive rolls, nozzles, contact tips and wire straighteners
are common between the MaxSA™ wire drives and
the Cruiser wire drive. The wire drive rotates about two
axes for setting torch drag/pull angle and torch tilt
angle.
The wire drive is mounted to two heavy duty X-Y
slides. The cross slides allow easy adjustment of the
electrode stick-out and position of the wire.
Driving the tractor is a permanent magnet dc motor
with a 5 stage gear box built with all metal gears. A
high resolution encoder keeps the tractor speed con-
sistent even at slow speeds. The wheels are made
from high temperature rubber specially bonded to an
aluminum core. Also mounted on the axle are guide
wheels and gears for operating on K396 track sections.
The flexible wheel configuration lets the tractor be
assembled in a manner for the best balance while
aligning the wheels for the tracking of the joint.
All of the controls are housed in a pendant that con-
nects to the tractor with two ArcLink cables. The pen-
dant housing is fabricated from aluminum to resist
impacts and high temperatures.
GENERAL FUNCTIONAL DESCRIPTION
The TANDEM CRUISER™ is a modular platform for
submerged arc welding.
RECOMMENDED PROCESSES
• Tandem SAW (AC, DC+, DC-) up to 1000 amps per
arc.
PROCESS LIMITATIONS
• The TANDEM CRUISER™ does not support open
arc procedures.
EQUIPMENT LIMITATIONS
• Inductance of the electrode and work cables may
affect arc performance. Do not coil excess cable.
• For robust digital communications, do not use more
than 200 feet of control cable.
• The Tandem Cruiser™ operates on 40 VDC only.
• There is no 115 VAC in the tractor.
•
The minimum turning radius of the Tandem
Cruiser™ is 10 feet when assembled with 3 wheels.
• The minimum turning radius of the Tandem
Cruiser™ is 20 feet when assembled with 4 wheels.
• The rubber wheels are rated to 500°F (260°C)
• The curved nozzle extensions may be used with up
to 3/16” wire.
• For use with 50/60 lb coils.
RECOMMENDED POWER SOURCES
• Power Wave ® AC/DC 1000
DESIGN FEATURES
Loaded with Standard Features
Arc Performance
• The Tandem Cruiser™ and Power Wave ® AC/DC
1000 combine for new levels of submerged arc pro-
ductivity.
User Controls
• Easy to read pendant displays information for the
lead and trail arc.
• 4 memories on the lead arc and 8 memories on the
trail arc for quick selection of common procedures.
• Full sequence control for tailoring the weld from
start to end.
• All welding controls located at the pendant, includ-
ing program selection.
• Laser pointer to aid in steering the Cruiser.
Wire Drive
• Changeable gears for feeding small diameter wires
at high speed and large diameter wires at low
speed.
• High torque, permanent magnet DC motor with
tachometer for accurate wire feed speed control.
• Three roll wire straightener included.
• Uses standard Lincoln submerged arc contact noz-
zles.
Tractor and Frame
• Permanent magnet DC motor with encoder for
steady, accurate travel speeds.
• All steel gears for long life.
• Easily engaged travel clutch.
• Fully assembled for track use.
• High temperature rubber wheels for superior trac-
tion and heat resistance up to 500°F (260°C)
• Heavy duty slides for adjusting the electrode posi-
tion in the joint.
