WIRE FEED HEAD AND

RECEPTACLE

The leads to the drive motor, gas solenoid, and the tach (hall effect device) are brought into the control box via the wire drive receptacle. This 14-pin recepta- cle also houses the gun trigger leads, the electrode voltage sense lead and the leads for the optional dual procedure switch. When the gun trigger is activated the control board energizes the gas solenoid, then the wire drive motor and welding power source. The con- trol board receives tach feedback information and adjusts the motor armature voltage to match the pre- set wire feed speed.
