Model 415 
Operation Manual 

 

 

WARNING

: Magnetic Fields from High Currents can affect  

pacemakers.  PACEMAKER WEARERS KEEP AWAY UNTIL 
CONSULTING YOUR DOCTOR. 

 

WARNING

: Disconnect the input power to the machine before 

opening or servicing.  Discharge all circuits that store high voltage 
such as capacitor packs. Only QUALIFIED service personnel should 
open this equipment. 

 

WARNING:

 Welding can cause fires or explosions. Do not weld 

near FLAMMABLE or EXPLOSIVE MATERIALS.  Watch for fire. 
Have the proper type of extinguisher in your work area. 

 

WARNING

: Welding Operators should wear non-flammable 

protective clothing, footwear and head gear. 

 

WARNING

: Never weld on sealed containers or pipes.  This may 

result in an EXPLOSION. 

 

WARNING

:  Welding produces high temperatures in both the 

welded components and the welding equipment.  Both can cause 
severe burns. Do not touch recently welded components.   Avoid 
touching internal components of the welding system soon after use. 
Avoid touching torch components and welding fixtures soon after 
welding.  

 

WARNING

: The welding arc emits ultra-violet (UV) radiation and the 

molten weld gives off infra-red (IR).  Both can burn eyes and skin if 
unprotected.  Suitable eye and skin protection must be worn. 

 

WARNING

: Weld materials can emit toxic fumes during welding.  

WELD ONLY IN AREAS WITH ADEQUATE VENTILATION

.

  

 

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.
