1.0 SAFETY PRECAUTIONS
The Model 205 is intended to be used only with AMI or EXEL weldheads for the purpose of
GTAW welding of metal tube. The system is not to be used for any other purpose, specifically
heating or cutting.
WARNING
The nature of the GTAW process creates some POTENTIAL
HAZARDS. In accordance with international safety regulations the
EXCLAMATION SYMBOL indicates that this equipment is considered
HAZARDOUS. The LIGHTNING FLASH SYMBOL indicates that
there are potential electrical hazards. The use and display of these
symbols make it the
OPERATOR’S RESPONSIBILITY TO ENSURE
THAT HE HAS READ AND/OR BEEN MADE AWARE OF ALL OF THE SAFETY-RELATED
ITEMS CONTAINED IN THIS MANUAL.
1.1 SHOCK HAZARD WARNING
HIGH VOLTAGE is present on exposed internal terminals. The ELECTRODE (tungsten /
weldhead rotor) is also an EXPOSED TERMINAL and by its nature the GTAW process requires
electrical potential to be present on the electrode during arc starting and during welding.
