The most frequently asked questions at Cal Manufacturing, Inc
"Calcables" provide solutions at your fingertips, technical resources
and content.
1.
Can you produce a cable even if someone else
manufactured it before?
The simple answer is yes. Cables
utilized in spot welding, resistance welding, robotic welding originate from
the OEM; however, it is not necessary to track back the manufacturer of the
original equipment. In fact, you may
find that the product we manufacture is actually more efficient and effective
incorporating the newest technology as well as aftermarket follow up to ensure
correct placement, bend radius recommendations, etc.
2.
How do
I figure out the correct cable I need? First off, look at your welding
equipment. If there is a lot of pulse,
kick or vibration during the weld process, consider extra-flexible copper
braided rope as it reduces breakage, fraying and pulling apart. Second, to determine the MCM (circular mill
size) you need to know the duty cycle, current and length of the cable (always
measured bolt hole center to bolt hole center).

Find
the closest duty cycle on the left and use the multiplier on the right - this
will give you the continuous duty current of the cable.
In
Diagram 1, locate the length and follow up to the continuous duty current,
angle over and you will find the correct MCM (circular mill size).
1.
How do you measure a shunt? This is always a good question and a valid
one, at that. Copper laminated shunts
come in literally thousands of designs from very small to extremely large
depending on their application. The
measurements of a shunt include the overall length (factoring in bend radii if
applicable), width and thickness (less clips).
My production line is down
due to cable failure.
Calcables has the ability to expedite same day shipping for down
production lines or other urgent needs.
NEW, this year is a
* Two-day expedited shipping program as well
for anticipated urgent needs. Life
happens at any time of the day and we make your emergency our emergency.
2.
What
MCM are our cables rated to? 150 MCM is typically the smallest circular
mill size, 250, 300, 325, 350, 400, 450, 500, 600, 650, 750, 800, 1000, 1200,
1500, 2000 are all available. Specialty
cables are available in sizes not listed; however, these are the most commonly
ordered circular mill sizes. Larger MCM
cables are often utilized in induction heating purposes and these are also
available upon request.
Frequently
asked questions related to resistance welding, spot welding,
robotic welding power leads/jumpers are not exclusive to the above; however,
these are definitely the top five.
Technical support related to recommended cable placement, bend radius
minimums, high temperature are all questions the engineers at CAL can answer
for your individual equipment, welding cell, robotic welding. Find the closest duty cycle on the left
and use the multiplier on the right - this will give you the continuous duty
current of the cable.
All cables are tested for water pressure, polarity extensively before shipping
