word for a harmful or dangerous situation.
1 GENERAL APPLICATION
The placement of spot welding on precious metal and precious metal alloys, on steel and
steel alloys as well as titanium and various NE-metals.
Not authorized for welding teeth fittings! (dental techniques)
Any usage other than given is prohibited.
Operation in outdoor areas is prohibited. Use in dry room areas only.
No liability of any kind will be assumed for the durability of welding spots. We
recommend that you always check the spots and to solder them in case of doubt.
2 INTRODUCTION
PUK 3 provides a long-awaited missing link between difficult joining techniques and laser
welding devices. With the help of an intelligent combination of high performance
electronics and precision mechanics, we’ve been able to create a unique spot welding
device. It’s small size, low weight and minimum energy use are important factors leading
to your advantage. Excellent ignition and welding characteristics allow a broad range of
use. With our welding device, you’re able to gain access to new dimensions of welding
techniques in the area of production and repair.

3 GENERAL SAFETY INSTRUCTIONS - READ BEFORE USING
BEFORE USING - READ ALSO THE ATTACHED SAFETY
PRECAUTIONS
3-1 SAFETY INSTRUCTIONS
Opening the device is permitted only by trained experts. Remove the plug before opening
the device and make sure that the device is without electrical power. Discharge all device
components that may store electricity.
Please consult an expert should any questions arise. Our customer service team with
expertly trained staff, necessary resources and equipment would be pleased to assist
you further at any time.
Always use original cables that are long enough and make sure that the clamp holding
the work piece is fastened properly.
Hazard conditions may be caused by electricity as well as by welding current.
It is illegal for non-professional electricians to handle parts that are directly connected to
the mains power supply, except in cases of pulling the mains plug and/or operating the
main power switch.
The device must be disconnected from the mains as soon as repair or service works is
needed. When leaving the place of work even for a short time, make sure that the
electrical outlet is blocked clearly.
Open circuit voltage is the highest and most dangerous voltage for welding current. The
highest permitted open circuit voltages are contained in your national and international
regulations according to the type of welding current, type of electrical source and the high
or low hazard levels at the workplace.
If you believe that operating the device is not possible without creating hazardous
conditions, then shut off the device and secure it against unauthorised use.
It is clear that a hazardous conditions are present when:
the device shows visible damage, or
or when functional errors occur
if it no longer functions properly.
Please follow relevant safety measures when handling gas bottles
PUK 3 can be operated in series using a mains voltage of 115V~
Yellow/green electric conductor = grounded terminal (PE) Other conductors L1 and N
are connected to phase and neutral of plug.
The welding device is set for 115 V ex works!
This means that it also may be operated using 110 volts due to its tolerance of +/- 15%.
Devices set to a different voltage than 115 V will be marked with a special sticker.
AUTHORIZED SERVICE PERSONNEL ONLY MAY OPEN THE DEVICE!
otherwise the manufacturer`s warrantee is invalid.
IF THE DEVICE HAS BEEN MADE FOR A SPECIAL VOLTAGE, THEN SEE THE
TECHNICAL DATA INDICATED ON THE DEVICE! THE POWER SWITCH MUST
CORRESPOND WITH THE MAIN VOLTAGE AND THE POWER RECEPTACLE OF
THE WELDING DEVICE. (See the technical data!)
PLEASE ENSURE THAT THE MAIN POWER BOX CAN SUPPORT THE USE OF THIS
DEVICE WITHOUT BLOWING A FUSE
USE ONLY THE PROVIDED POWER CONNECTORS!
