* An allowance of 1 3/4" is made for thickness of bench top. A thinner top permits a corresponding increase in horn spacing.
** Can be swung left or right or moved up or down on the main tubular support. It can also be adjusted approximately .3 to .5 inches in or out in order to use offset electrodes.
*** Two ranges are provided by means of two interchangeable compression springs, both are provided

Taylor-Winfield recommends the above indicated fusible isolation switches and cable sizes, but customer should check local, city and state electrical code requirements.

The switch size, fuse size and feeder cable size are selected on short circuit capacity of equipment; that is, with electrodes shorted. When using this type of welder, the actual welding current may be considerably less than the indicated maximum short circuit value of secondary current, since the welding job will normally have considerable resistance.
