The new Truncator is a separate module, designed and engineered for truncating of ground Tungsten electrodes for TIG welding. The new Truncator module can be mounted on the Ultima-TIG and Ultima-TIG-Cut grinders.
Easy to use; Grind an electrode tip on your Ultima-TIG. Loosen the electrode from the electrode holder and secure it in the adjustment for the Truncator Insert the electrode holder in the Truncator. With the grinder switched on, press the electrode holder in to truncate the electrode tip. Switch off the grinder and remove the electrode from the electrode holder. The size of the truncated tip can easily be adjusted to any desired diameter.
The Truncator also works with AutoGrind Digital mounted on the Ultima-TIG.
For better welding results, there are mainly two reasons to truncate the tip of the freshly ground electrode. In high-current applications, the truncated geometry eliminates the risk of melting off the tip into the weld pool, causing contamination. In AC applications, the truncated geometry reduces the risk of obtaining an excessive ball at the tip. Knowing that an excessive ball causes an unstable arc and might fall and contaminate the weld.
