Fixture Type Transformers |
Applications:
The perfect choice for multi-spot welding fixtures.
Features: Single secondary or two isolated. impedance-balanced secondaries are provided, with various tap switch mounting positions and primary disconnect plugs available.
Ratings: 5 to 220 KVA
Machine Type Transformers |
Applications:
Predominantly used in press, seam, or rocker arm
welding machines.
Features: Secondary connection pads conform to RWMA standards. Voltage range covers up to 60% of the high tap voltage. Secondary end is potted with epoxy resin to provide added support to the connections and seal out contaminants.
Ratings: 20 to 600 KVA.
Inverter Power Supply/MFDC/HFDC |
Perfect
for robotic applications, We offer a full range of high frequency DC
power sources that deliver high secondary current in a compact,
lightweight package.
We can provide both industry standard and custom design high frequency DC power sources that evenly distribute primary current demand across 3-phase systems.
Operating ranges up to 850 primary volts, and frequency ranges up to 1,200 hertz.
DC Power Supplies/Special Power Sources |
As
the world's leading manufacturer of DC power sources for resistance
welding and heating, RoMan has the engineering expertise to
determine the power source most useful in your situation and take it
from design to delivery according to your demanding production
schedules.
Roman also manufactures special transformers and DC power supplies for plating and heat treating applications.
Available in single-phase or three-phase configuration, RoMan DC power sources range in size from 10 to 4,000 KVA.
Tap Switches |
RoMan
manufactures tap switches to regulate output voltages for welding
transformers and other devices requiring switching on the primary.
Available in single-, two-, or three-phase configurations from 100 to 1,000 amps, each tap switch can be custom configured to meet customer specifications.
Grounding Reactors |
Grounding
Reactors provide protection from electrical shock when direct
grounding of the secondary circuit is not practical. They are
especially effective on portable guns, and push-pull or series
circuits in multi-spot welders.
Available in several sizes and voltage ranges, RoMan grounding reactors can be used with any resistance welding transformer, regardless of make, model, or age.
Impedance Meter |
RoMan's
portable impedance meter features a variable low-voltage power
source that measures tip-to-tip impedance of:
- Single phase AC resistance welding machines
- Portable Guns
- Transguns (with or without transformers)
- Kickless cables
Weld Current Equalizer |
Transgun/Robot Type Transformers |
Applications:
Resistance welding transguns for
robots or multi-spot fixtures.
Features: Compact, lightweight design is suitable for close coupled welding gun mounting. Available with single secondary voltage, or variable secondary voltage range with tap switch.
Ratings: 20 to 100 KVA.
Portable Gun Type Transformers |
Applications:
Any welding installations using portable welding
guns, or remote robot guns.
Features: Secondary connections designed to accept low reactance dual conductor (kickless) welding cables. Available in wound and stacked core models. Integral hanger accommodates overhead mounting.
Ratings: 50 to 400 KVA
