1. GENERAL SPECIFICATIONS AND NOTES FOR CONSULTING THIS
MANUAL
The "T 422" welders are made using INVERTER technology. They are extremely compact
and versatile devices that can be used in all those situations that require minimum
obstruction, combined with the highest performance.
These welders use both manual and synergic MMA, TIG (lift).
The innovative operator interface system, which uses a large 5,7" TFT colour screen,
allows for simple and intuitive use of the equipment, without renouncing on the possibility
to personalise all of the welding settings.
All of the main parameters of the machine are stored on a memory card (SD-Card),
keeping the equipment constantly up-dated with the latest welding developments. If the
memory card is removed the equipment will cease to function, providing an optimal anti-
theft system and safeguard against inappropriate use.
Thanks to the advanced control techniques adopted, the product is extremely reliable and
easy to use.
This instruction manual provides detailed information on the machine settings: reading the
entire manual will allow you to appreciate the extreme flexibility and practicality of use.
Caution: the device must only be used in the manner and for the purpose described in this
manual. Never use inappropriately or for any other purpose.
