Welding Power Generator Installation Accessories/Bracketing Components


We offer a number of generic/universal bracketing accessories designed to facilitate ZENA mobile welding system power generator installations as well as installations of ZENA power generators in marine, automotive, and DC Genset applications.

These bracketing accessories range from:

Variations on our custom bracket kits which provide bolt-in mounting of belt driven underhood hydraulic pumps (typically clutch pumps) are also available for the same models of trucks as our custom alternator bracketing kits / generator bracketing kits. Call for more information.

While not a bracketing item, one of our most popular installation accessories, by far -- particularly for vehicle installations, are our low cost automatic engine speed control kits. The vacuum powered model ASC1 shown below provides one example, an electrically powered model (our model ASC3) is also available.

Below you will find illustrations of most of our generic/universal components as well as our bolt together universal bracket kit. For more on our custom bracket kits CLICK HERE.

AIRT101 Spring Loaded Belt Tensioner

Fully compatible with the UB2 bracketing kit as well as all other ZENA bracketing components, the AIRT101 is an inexpensive fully adjustable bi-directional spring loaded belt tensioning device designed to be used with flat or V-type idler pulleys (order separately -- call) in a V-belt drive system to maintain a constant belt tension (10-30 lb.).

The use of such a device can GREATLY improve belt performance and belt life-- frequently eliminating the need for dual drive belts in high power generating systems.

Idler Pulley

Idler pulleys can be used to improve belt drive performance in a number of ways. For example, when belt wrap around a pulley is insufficient to provide proper drive an idler can be employed to direct the belt path so as to improve the percentage of pulley covered by the belt. Idlers can also be used to reduce belt vibration by supporting a segment of belt which is prone to vibration/oscillation

A key point to remember when sizing/selecting an idler is that the idler pulley diameter should be 130% the size of the smallest pulley in a belt system

ZENA Add-A-Pulley power takeoff adapter kit

photo of the ZENA AAPK Add-A-Pulley alternator power take off accessoryOur unique Add-A-Pulley adapter kit has been designed to make installation of ZENA power generators very easy in vehicles which have serpentine drive belt systems. It can be installed easily (attaching to the existing alternator pulley) and provides, as a secondary benefit, the ability to use a reduced engine speed when welding.

A number of models are available, and most popular 4x4, truck, and auto makes are supported. When ordering make sure you advise you vehicle's make, model, engine size, and alternator type (if known).

The diagram shown below is an excerpt from the Add-A-Pulley installation instructions.

ASC1 Automatic Engine Speed / High Idle Control Kit

This is our most popular accessory for vehicle installations.

While not necessary for proper equipment operation, an automatic engine speed control will save fuel and reduce engine noise when welding for extended periods. The model ASC1 is controlled electronically by the ZENA system. It automatically increases your engine speed to your preset welding speed when you activate welder power then reduces your vehicle engine speed to your normal idle speed whenever you are not actually welding.

NOTE: This accessory can also be used in a "stand-alone" configuration as a low cost high idle control for emergency vehicles and service vehicles of all types which have a vehicle vacuum source available.

The ASC1 uses engine vacuum for its actuator operation. However, for engines / applications in which a suitable vacuum source is not available order our model ASC3. This model uses an electrically activated actuator.
