Spot welders stationary PTE 28 LCD 824051

 

Device for double-sided welding of low-carbon, stainless, galvanized, and spring steel sheets with a maximum thickness of 5+5mm.

 

Designed for production work.

 

Spot welding parameters:

 

• power (%): spot welding current expressed as a percentage value relative to the maximum value;
• approach (cycles): waiting time in cycles before delivering current, starting from the contact of the electrodes with the workpiece;
• ramp (cycles): time in cycles used by the spot welding current to reach the value set using “power”;
• spot welding time (cycles): time in cycles during which the current value is maintained at the set value;
• pause time (cycles): time in cycles during which the current is zero between two consecutive pulses (only in pulsing mode);
• number of pulses (nr): 1 - spot welding will end after the spot welding time (4); if greater than 1, indicates the number of current pulses delivered by the device (pulsing function);
• round synoptic indicator, with the numerical value of the set cycles in the central part;

 

Each time the machine is turned on and before pressing the “START” button, it is possible to change the mode in which you intend to set the welding parameters:

 

• “REDUCED” mode = EASY: allows quick and intuitive selection of the two main welding parameters “POWER” and “spot welding time”. This mode does not allow saving personal programs.
• “EXTENDED” mode = EXPERT: allows selection of all welding parameters described in the previous paragraph. This mode allows saving personalized programs.

 

 

Characteristics:

 

• Two-phase power supply.
• Adjustable electrode pressure.
• Foot-operated electrode pressure.
• Control pedal with adjustable spring.
• Adjustable arm clearance from 160 to 245mm
• Requires water cooling for arms and electrodes
• Equipped with a set of water-cooled arms and electrodes L=350mm
• Overload protection
• Fan-cooled
