Hydra-Torque 
Torque Converter Welder

The latest torque converter welding machine model is designed and adjusted to solve any TC Problems. Available in options WS 3.1 (single-gun) and WS 3.2 (dual-gun).


​FEATURES:

  • The torque converter welder uses an 8-point welding algorithm.

  • Setting the thermal clearance with an accuracy of 0.01 mm can be done at the touch of a button.

  • The torque converter welder is equipped with additional lighting in the work area and an exhaust fan for removal of the welding by-products.

WS 3.1 Torque Converter Welder

Hydra-Torque offers a simplified upgrade procedure from a single welder to a dual welder system via an easy software update if you find you need this feature at a future date.
 

The Hydra-Torque heavy-duty welder can accommodate a torque converter with a maximum diameter of 480mm (18.9 in) and a maximum height of 380mm (15.0 in).


The heavy duty torque converter welder has a maximum clamping diameter of the lower chuck of 64mm (2.5 in) and a maximum clamping diameter of the upper chuck is 160mm (6.3 in).


The heavy duty upgrade welder design included an enlarged faceplate and chucks, reinforced bearings, and an increased pinole stroke range.


Hydra-Torque equipment provides professional level quality to any Automatic  transmission rebuilders - from family-size shops to large remanufacturers. The Hydra-Torque line of torque converter machines has been developed to guarantee a fair combination of the highest quality, competitive pricing, and high reliability - all topped up by advanced training and outstanding technical service.

Dual chuck system


Adjustable (Set-tru) or precision chucks and bearings for the highest precision are standard equipment on the torque converter welding stand. Our double-chuck design removes the need for centering bushings for the pilot or the hub.

Electronic Control

The electronic control system allows technicians to adjust the speed of welding, switching from welding to rotating mode with very high accuracy.

  • Operation of the welder is easy and simple with a single touch screen panel that allows for control and adjustments of each variable of the welding process.

  • The easy-to-use industrial touch screen can be operated either with or without protective gloves.

  • The torque converter welder control panel is equipped with a series of manual control buttons.

  • In the event of damage to the touch screen, the emergency mode allows the operator to control the torque converter welder using these manual control buttons.

  • Software and firmware updates are made easy via Ethernet and USB connectors located on the operator’s panel.

AccuTurn is our patent pending solution for speed and accuracy when  welding. The speed of rotation between the weld points is less than 1 second, which helps to reduce axis skew as the weld points cool down and accelerates the torque converter welding cycle.

FREQUENTLY ASKED QUESTIONS

What welders are provided with the machine? We supply JASIC TIG 250  welder in our torque converter welding machines.

Can I order it without welders and supply my own? Yes. Please specify you with to order the machine with the “Welder Delete” option. This allows you to source a comparable Lincoln or Miller welder to use in the machine.

What kind of a welding algorithm does the welder have to keep distortion to a minimum? The torque converter welder uses an 8 point welding algorithm as it rotates the torque converter. The first 7 points are evenly spaced tack welds with the last point initiating the full weld circle. This process is automatic once started and keeps distortion to a minimum.  

Hydra-Torque equipment electrical technical requirements: The Torque Converter Welder for the US comes as 230V/60Hz/3-Phase standard. Other voltage configurations are available upon request and can be quoted and specified at the time of order.

Additional tools required for rebuilders of Torque Converters:

  1. Lathe for cutting open the torque converter.

  2. Quality parts cleaning system.

  3. Torque Converters spare parts.

Where can I get pare parts for Torque Converters? Most popular parts for the Torque Converter would be friction linings, friction plates / discs, O-rings, seal rings. Local suppliers or international torque converter rebuild parts vendors can provide you with all spare parts for both valve body and torque converter repairs. Hydra-Test can advise or recommend viable options if needed.

Which gas mixture is required? Typically, 80% СО2 / 20% argon (other typical transmission workshop gas mixtures are also appropriate). The torque converter welder wire is the 0.8mm diameter.

TORQUE CONVERTER IMPELLER HUB REPLACEMENT TOOL

There are different methods used for hub replacements. The preferred method comes down to personal choice. Depending on your torque converter repair equipment and the lathes available, some customers will remove the damaged hub before separating the torque converter as this means your hub machining would be true to the spigot on the front cover, which is held in the lathe when separating the torque converter.


Other clients would separate the converter first and then hold the outside of the impeller in a lathe with opened jaws. Hence holding and machining only the lid instead of the entire converter. This method allows you to inspect the internals and either side of the lid before you start machining the hub.

 

Regardless of which method you use, you do need to measure the height of the original hub before you start the machining process. The next step is to decide whether you want to use the flanged or butt mount style replacement hub. Butt mounted hubs are easier to fit in terms of machining as all you need to do is to cut off the damaged hub and then machine a perfect stepped hole based on the outer diameter of the replacement hub. Therefore, a hole of the size of the replacement hub will centralize the hub and then simply machine the depth until your hub sits at the same height as the original.
 

The only negative with this method is that the replacement weld is right up against the edge of the hub and you need to make sure that it is not too high or too big because it could interfere with the pump seal on installation.


The flanged hub replacement is easier to weld in place as the replacement weld is further out from the hub but the machining can be more complicated on occasion when trying to achieve the same height as the original. This is dependent on type but generally easier to achieve if you have the option of holding the lid independently on a lathe with opened jaws.


Once the damaged hub has been removed and a replacement fits into a machined hole at the same height as the original, it needs to be welded in place. We suggest that MIG welding is used for this process unless you are a skilled and trained TIG-welder. In our experience TIG welding is too hot and quite badly discolors or distorts the hub.


Before welding, the hub needs to be held in place and the impeller needs to be centralized on the turntable of the welding machine. The hub itself does not need to be centralized on the impeller as the hole size should be exact and this means that the hub is automatically centralized as long as the impeller was held centrally when machined.


The recommended option of holding the hub in place is to machine adapters to fit perfectly inside the hub and is held in the top jaws of the welder. This process aligns the impeller hub for you and holds the hub in place for welding. Just make sure that the impeller is fixed to the turntable so that it will turn with the table when welding.
