1. GENERAL SPECIFICATIONS AND
NOTES FOR CONSULTING THIS MANUAL
The DS323C, welders is 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 and MIG/MAG (short arc, pulse or double pulse).
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 antitheft 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 exibility 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.
