Introduction

We congratulate you on the purchase of your new HTP MIG 2400 Welder.  Your HTP MIG Welder will allow you to weld items you 
wouldn’t have thought possible to weld.  Your HTP MIG Welder can weld steel, stainless steel, aluminum, cast iron, HSLA steels 
and even braze steel.  With proper care and maintenance, your new HTP MIG Welder will deliver years of trouble-free service.  
However, it is very important that you read the following manual completely.

Safety Suggestions

ELECTRIC ARC WELDING PRODUCES ULTR-VIOLET 
RAYS WHICH ARE HARMFUL TO SKIN AND EYES.  
ULTRA-VIOLET RADIATION CAN PENETRATE 
LIGHTWEIGHT CLOTHING, REFLECT FROM LIGHT-
COLORED SURFACES AND BURN THE SKIN AND EYES.  
WEAR FLAMEPROOF WELDING GLOVES WHICH ARE 
NOT OILY OR GREASY.  THE OIL OR GREASE ON THE 
GLOVES MAY IGNITE.

•  Wear a heavy, pocketless, long sleeve shirt, cuffless  

 

  trousers, and high-topped work shoes.  Wear a full-face    
  welding helmet with a number eight or darker lens  

 

  and a cap.  These precautions will protect eyes, hair, face,   
  and skin from arc rays and hot material.

•   To avoid fire, do not weld on wood, plastic tile, or 
  carpeted floors.  Concrete or masonry floors are safest.

•  Do not weld on drums, barrels, tanks or other containers    
  until they have been cleaned as described in AWS Standard  
  A6.01.

•   Provide adequate ventilation in the welding area at  

 

  all times.  Do not weld on galvanized zinc, cadmium  

 

  or lead beryllium materials unless you are POSITIVE  

 

  that sufficient ventilation is provided.  These materials  

 

  produce toxic fumes.

•  Do not weld in areas close to degreasing or spraying  

 

  operations.  Chlorinated hydrocarbon vapors may react  
  with the ultra-violet rays and form highly toxic phosgene    
  gas.

•   If you develop momentary eye, nose or throat irritation    
  during welding, stop welding immediately.  This is an  

 

  indication that ventilation is not adequate. Do not continue  
  to weld until ventilation is improved.

•  Exposed, electrically hot conductors or other bare  

 

  metal in the welding circuit, or ungrounded electrically hot  
  equipment can fatally shock a person whose body becomes  
  a conductor.  Do not stand, sit, lie, lean on or touch a wet    
  surface when welding.

•  Frequently inspect cables for wear, cracks, and damage.     
  Replace those with excessively worn insulation to avoid  
  a possible lethal shock from bared cable.

comply as applicable.
