GENERAL SPECIFICATIONS AND NOTES 

FOR CONSULTING THIS MANUAL 

The “DP231C” 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 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 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.
