WARNING: Most GTAW gases like argon are non-toxic, however,
argon is heavier than air and will displace the normal atmosphere in
enclosed areas. DO NOT WELD IN ENCLOSED AREAS WITH-
OUT PROPER VENTILATION OR RESPIRATORS.
WARNING: AMI factory training is essential for all Welding Opera-
tors and Maintenance Technicians who operate AMI equipment.
Consult factory for dates of training classes and other training
