Lead Wire Protection

The straight or right angle header on the Watt-Flex® cartridge heater is designed as a transition piece between the heater and lead wire protection, usually either stainless hose or braid. The opening is slightly larger than the diameter of the heater which allows for heater expansion in the bore. And the header is welded on one side to accommodate this bilateral expansion.

Occasionally, a customer will use the header in the process of insertion into the bore by tapping (or banging) it with a hammer and screw driver. Since the header is welded on one side, this process may cause the header to cock over at an angle, such that it comes in contact with the insulation over the heater terminal. From there, it is simply a matter of time before the woven fiberglass insulation used with high temperature wire will break down.

The other problem is that the beating on the header can cause a cracking or breaking of the weld so that it fails over time, resulting in the header pulling away from the heater (see above). This will contribute to premature failure if there is any movement of the heated work piece.

The solution to this problem is welding the header on both sides. If the heater is longer than 12" (depending on diameter), it will still expand in the bore to the point that contact is not a concern. This "weld-around" technique will provide stability and integrity of the header so that it can take a beating and not be affected. Dalton Electric believes that it is our responsibility to accommodate the customer's application and cause them to have to change their processes as little as possible.

Friday Funnies

A man in Topeka, Kansas decided to write a book about Churches around the country. He began by flying to San Francisco and started working his way east. Going to a very large church, he began taking photographs and making notes. He spotted a golden telephone on the vestibule wall and was intrigued with a sign, which read 'Calls: $10,000 a minute.'

Seeking out the pastor he asked about the phone and the sign. The pastor answered that this golden phone is, in fact, a direct line to heaven and if he pays the price he can talk directly to God. The man thanked the pastor and continued on his way. As he continued to visit churches in Seattle , Dallas, St. Louis, Chicago, Milwaukee, and around the United States, he found more phones, with the same sign, and the same answer from each pastor.

Finally, he arrived in Massachusetts. Upon entering a church in Boston, MA. Behold - he saw the usual golden telephone. But THIS time, the sign read "Calls: 35 cents." Fascinated, he asked to talk to the pastor, "Reverend, I have been in cities all across the country and in each church I have found this golden telephone and have been told it is a direct line to Heaven and that I could talk to God, but in the other churches the cost was $10,000 a minute. Your sign reads only 35 cents a call. Why?"

The pastor, smiling benignly, replied : "Son, you're in Boston--home of the Red Sox, New England Patriots, Boston Celtics, and the Boston Bruins ! 'You're in God's Country', It's a local call.
