PC 70i, 100i Operating Manual

 

4.0  SET-UP FOR PCM

 

Conventional operating procedures apply when using the cutting power source, i.e. connect work lead 

directly to work piece and cutting torch is used to POWER adaptor. Wide safety margins provided by the coil 

design ensure that the cutting power source will withstand short-term overload without adverse effects. The 

cutting current range values should be used as a guide only. Current delivered to the arc is dependent on the 

cutting arc voltage, and as cutting voltage varies between different classes of electrodes, cutting current at 

any one setting would vary according to the type of electrode in use. The operator should use the cutting 

current range values as a guide, and then finally adjust the current setting to suit the application.

WARNING: 

                                                                                                                                                                         
 

Before connecting the work clamp to the work and inserting the parts in the cutting torch make sure 

the Primary power supply is switched off. 

                                                                                                                                                                         

 

 

CAUTION 2: 

                                                                                                                                                                         

 

Remove any packaging material prior to use. Do not block the air vents at the front or rear of the 

Cutting Power Source.
