Safety Messages
2.1 Using the Correct Connection Terminal
Use the appropriate connection terminal that is compatible with the fit-
ting type used. Be sure the contact is firmly established and do not use
burnt connection terminals or terminal adapters that are not designed
for the intended use.
2.2 Improper Use of the Welding and Power Supply Cables
Do not carry the HST300
Pricon
+ by its cord and do not pull the cord to
unplug the unit from the socket. Protect the cables from heat, oil, and
cutting edges.
2.3 Securing the Fitting and the Joint
Use clamps or a vice to secure the fitting and the joint to be made
before welding. The fitting manufacturer’s installation instructions, DVGW,
DVS, European and national regulations will have to be respected in all
cases.
The welding procedure for a fitting must never be repeated, since this
may cause parts under power to be accessible to the touch.
2.4 Cleaning the Welding Unit
The HST300
Pricon
+ must not be sprayed with or immersed in water.
