Considerations About Welding And The Effects Of Low Frequency Electric And  
Magnetic Fields  
NOTE  
The following is a quotation from the General Conclusions Section  
of the U.S. Congress, Office of Technology Assessment, Biological  
To reduce magnetic fields in the workplace, use the following  
procedures:  
Effects of Power Frequency Electric  
&
Magnetic Fields  
1. Keep cables close together by twisting or taping them.  
2. Arrange cables to one side and away from the operator.  
3. Do not coil or drape cables around the body.  
Background Paper, OTA-BP-E-53 (Washington, DC: U.S.  
Government Printing Office, May 1989): “. . . there is now a very  
large volume of scientific findings based on experiments at the  
cellularlevelandfromstudieswithanimalsandpeoplewhichclearly  
establish that low frequency magnetic fields can interact with, and  
produce changes in, biological systems. While most of this work is  
of very high quality, the results are complex. Current scientific  
understanding does not yet allow us to interpret the evidence in a  
single coherent framework. Even more frustrating, it does not yet  
allow us to draw definite conclusions about questions of possible  
risk or to offer clear science-based advice on strategies to minimize  
or avoid potential risks.”  
4. Keep welding power source and cables as far away as  
practical.  
5. Connect work clamp to workpiece as close to the weld as  
possible.  
About Pacemakers:  
The above procedures are among those also normally  
recommended for pacemaker wearers. Consult your doctor for  
complete information.

SHOCK SENSOR UNIT ASSEMBLY AND  
INSTALLATION TO ROBOT (Figure 3-3 And  
Figure 3-4)  
WARNING: ELECTRIC SHOCK can kill.  
The optional shield sleeving is for covering the torch  
cable to prevent high frequency from interfering with ro-  
bot operations.  
Do not touch live electrical parts.  
Shut down robot and welding power source,  
and disconnect input power employing lock-  
out/tagging procedures before inspecting or  
installing.  
IMPORTANT: When installing shield sleeving, be sure  
end with lead and attached ring terminal is at console  
end of the torch cable.  
Lockout/tagging procedures consist of padlock-  
ing line disconnect switch in open position, re-  
moving fuses from fuse box, or shutting off and  
red-tagging circuit breaker or other disconnect-  
ing device.  
To install shield sleeving, proceed as follows:  
1. Unscrew sleeve from torch head assembly  
(see Figure 3-5).  
2. Disconnect fittings and remove torch head as-  
sembly.  
MOVING PARTS can cause serious injury.  
Keep away from moving parts.  
3. Insert torch cable into shield sleeving at end with  
lead and attached ring terminal.  
HOT SURFACES can cause severe burns.  
Allow cooling period before servicing.  
4. Slide shield sleeving over torch cable until end of  
torch cable exits opposite end of shield sleeving.  
To assemble and install the shock sensor unit, refer to  
Figure 3-3 or Figure 3-4 and proceed as follows:  
5. Reconnect fittings from torch cable to torch head  
assembly (match color-coded markings).

4. If applicable, remove the existing clamps sus-  
pended from the outlet cable support arm and re-  
place them with the two supplied clamps. Route  
torch cable through new clamps so there is about  
3-1/2 ft. (1 m) of cable between the top of the  
shock sensor and the first clamp (see  
Figure 3-10).

and disconnect input power employing lock-  
out/tagging procedures before inspecting or  
installing.  
6. Route remaining end of torch cable to the WC  
100B welding panel for internal connections (see  
Step 3, Section 3-6B).  
7. The supplied high frequency filter box prevents  
noise interference at the shock sensor circuit in  
the Robot Control. To install the filter, proceed as  
follows:

GROUND  
CABLE  
CONNECTIONS  
(Figure 3-10 And Figure 3-11)  
IMPORTANT: If welding power source is equipped with  
a plastic case, only one ground cable is necessary for  
connecting to robot base.  
See Figure 3-10 or Figure 3-11 and install three sup-  
plied flat, braided ground cables as follows:  
4. Install cable hanger assembly with tool balancer  
onto robot Axis 3 housing.  
1. Connect one end of the ground cables to the cus-  
tomer-supplied ground rod (see robot Owner’s  
Manual).  
5. The torch cable is enclosed in a black protective  
case. Secure torch in torch clamp using supplied  
shim. Position torch handle so that there is  
approximately 4 in. (96 mm) between the bottom  
of the torch clamp and the torch tip. Clamp torch  
cable to tool balancer on cable hanger and route  
cable through support bracket.  
2. Connectremainingendofonegroundcabletoro-  
bot base as follows:  
a. Locate unused threaded hole on robot base.  
b. To ensure good electrical conduction, scrape  
away enough paint from around the hole so that  
the ground cable terminal will touch bare metal.  
IMPORTANT: Before operating, see Section 4 and ro-  
bot Owner’s Manual for instructions for absolute offset  
c. Attach ground cable terminal to base with sup-  
plied 12 mm bolt.

plied cord through strain relief on rear of PAW In-  
terface panel.  
This button starts shielding gas flow when the Run/Set  
switch on the WC 100B welding panel is in the Set posi-  
tion. When the switch is in Run position, pressing the  
button starts shielding gas flow and 5 seconds later  
plasma gas flows and the pilot arc ignites.  
3. Installing terminal connectors for connecting to  
terminal strip 6T onto leads at end of cord inside

strain relief.  
Pilot arc can cause burns – keep away from  
torch tip when pilot arc is present.  
5. Reinstall side panel onto PAW Interface panel.  
The pilot arc can be intermittent or continuous  
depending on the application. ALWAYS point  
torch away from personnel and toward work  
when starting the pilot arc or leaving the pilot arc  
on continuously.  
IMPORTANT: The remote Gas Set/Pilot Arc Start  
switch operates the same as the front panel push button  
switch (see Section 3-10).

SETTING UP PLASMA TORCH FOR MRV  
ROBOT (Figure 4-1)  
1. Check System Data settings against the test  
sheet supplied with the unit. These should match  
before beginning installation.  
The plasma torch does not require any changes to data  
in PARMTER/SYSTEM/TOOL PARAMETER. The stan-  
dard I-bar is used for adjusting torch position and for  
position recovery after a robot crash. Mount plasma arc  
welding torch, install tip gauge, and follow mounting ad-  
justment procedures according to instructions in Sec-  
tion 4 – System Set Up in the robot Owner’s Manual.  
Loosen torch clamp setscrews and position torch so that  
tip gauge touches I-bar reference point. Retighten set-  
screw.  
2. Mount plasma arc welding torch according to  
Section 3-3 of this manual. Make sure that sup-  
plied brass tip gauge and holder have been  
installed on torch.  
3. Do tool center point adjustment according to Sec-  
tion 4.6 of the robot Owner’s Manual.  
4. The universal J-bar is included to record exact  
torch position so that it is possible to recover posi-  
tion in case of a robot crash. Install universal J-  
bar as follows:  
After completing torch adjustment procedure, remove  
tip gauge and reinstall cup onto end of torch.

MARKING POSITION OF TORCH HEAD AS-  
SEMBLY (Figure 4-2)  
a. Remove 2 screws and cover plate from bottom  
of Axis 5 gear housing.  
When the mounting adjustment procedure is complete,  
place scribe marks on the torch head assembly and  
sleeve to mark the torch head assembly position for fu-  
ture alignment adjustments.  
b. Install universal J-bar onto Axis 5 by aligning in-  
dex pin with hole in housing, and securing with  
supplied screws.

Have only qualified person familiar with electronic equipment perform this installation.  
The user is responsible for having a qualified electrician promptly correct any interference problem resulting from the  
installation.  
If notified by the FCC about interference, stop using the equipment at once.  
Have the installation regularly checked and maintained.  
Keep high-frequency source doors and panels tightly shut, keep spark gaps at correct setting, and use grounding and  
shielding as shown in Figure 6-3 to minimize the possibility of interference.
