safety glasses and gloves. Avoid wearing rings, metal watches and clothes with either metal accessories or
components.
Protect the operator from possible spatters of melted material.
Keep the welder working area free from flammable materials. In case the material to be welded produces either smoke or
fumes, install a proper fume extractor.
In addition to the information stated on this paragraph, always operate in accordance with all the relevant
laws in force.
SELF CONTAINED WELDING SYSTEM DESCRIPTION
The welder has been designed for car body shop repairs and an operator working on a flat surface must use it. Pay
attention to both electric cable and pneumatic air hose.
This machine has not been designed for manufacturing works.
WELDING CONTROL UNIT
RELEASE SOFTWARE 95-07
The welding control unit is used to control the welder attachments and, in particular, the thyristor regulating the welding
current. The welding control unit is a microprocessor designed for cable resistance welders for car body shops.
Differently from a standard control unit the welding control unit shown in this manual carries out two different working
cycles for gun and multifunction gun; moreover, the multifunction gun working cycle is equipped with the sheet metal
heating function. The welding control unit can be used for welders with both pneumatic and hand-operated gun.
MAIN FEATURES
•
Synchronous thryristor drive with phase shift control for welding current adjustment.
•
Simplified programming by means of four buttons.
•
Regulation of first phase shift delay to obtain the best balance of machine line current.
•
Control of solenoid valve 24 Vdc 7,2 W Max with protected output against any short circuit.
•
Separate working cycles for gun and multifunction gun
