DC welder for those^ infrequent in-the-field jobs he's called upon to do. Sure enough, after trying a couple of different combinations of the scrap components, he came up with what must be the least expensive (and steangest looking! arc welder ever assembled. Essentially, the welder is powered by the roughly 50 amps that the Delco-Remy alternator is capable of producing . . . and is adjusted by varying the speed of the lawnmower engine. But the 12-volt battery is needed to balance out those surges that occur when the arc is struck or broken. Furthermore. Dennis found that the setup worked a lot more smoothly with two 1-1/2-ohm. 8-amp Chrysler product ballast resistors placed in series with the field of the alternator, to cut the field voltage to about 6 volts. (In fact, without the two resistors, striking an arc would nearly kill the 3-HP Briggs & Stratton engine!) Considering that the parte for the project are almost all scavenged, the welder is amazingly versatile. For one thing. DC capability is often preferred for smooth sheetmetal work, and our lawnmower unit can havle its polarity reversed for changing the penetration and spatter qualities of ite arc! There are. however, a few limitations »o the tool's capabilities. First, the maximum heat of the arc is about 60 amps, so the device won't penetrate more than about 1/4* into steel. In addition, it's best not to use the welder for more than about 20 minutes at a time ... to avoid overheating the alternator (the thermal overload switch shown in the schematic drawing automatically tells you when enough is enough). And finally, the unit's low-voltage DC current presents both an advantage and a disadvantage over conventional AC power. Because the voltage of a circuit determines the distance a spark will jump, the rod used with our portable welder must be held steadily close to the surface of the worft to maintain an arc. But. because it is a direct-current welder, there's little tendency for the rod to become stuck. Of course, the most astounding thing about Dennis’s welder is how little it cost. The only components that our researcher was forced to buy were the resistors. which he located at the neatest auto partr. s And—even if your storehouse of valuable '" doesn't equal MOTHER'S—you should still to purchase the resistors, wires, switches, pulleys (between 1:1 and 1.5:1, ‘ on the RPM rating of the alternator), and V-belf. for less than $20. When you think about it. a $20 DC arc welder, with a built-in dolly, might be the workshop bargain of the year!

Seniors Plan Activities

STONE HARBOR - Of the borough Seniors, 54 members have signed up to attend the 76 House dinner show, according to chairman Gertrude Cerny. Sara Brady, county representative, said all were invited to attend the County’s annual Jamboree June 17 in the Avalon Hall. The group was invited to attend the Burdette Tomlin Hospital luncheon at Henny’s May 5. That evening Harry Strohmetz. president. announced the County Historical Society will have a slide film on Cape May and Cape May County to show the group.

The term ''lumbago” is commonly used for any form of low back twin. Actually, lumbago is a form of rheumatism which can be caused by improper lifting, fatigue or over-exertion. It results in severe contraction of one or more of the large muscles of the

low back area.

The lumbar vertebrae are supported by muscles and ligaments. Any un-
