Welding Work

    

    

Warning: Suffocation from Welding Fume 

 Always be sure to wear a fume-proof mask when welding as the fumes 

generated during welding include harmful gases and dust. Also be 

careful that the wind direction is not such that it will cause fumes to be 
inhaled and always operate the equipment in a well-ventilated area.

 

Warning: Fire 

 Keep any ignitable items (such as fuel, gas and paint) or inflammable 

items away from the work area due to the scattering of weld spatter that 
occurs during welding.

 

Warning: Electromagnetic Interference 

 Persons using a heart pacemaker are not allowed near the welder or 

welding work area while welding is being performed without the 
permission of a doctor. The welder generates a magnetic field while 

energized that can negatively affect pacemaker operation.

 

 

Caution: Injury to Eyes and Skin 

 Always be sure to wear arc-proof glasses (refer to the table below), 

clothes that completely cover the skin and other protective gear when 
welding to protect the eyes and skin from harmful light rays generated 

during welding.

 Always be sure to wear leather gloves, apron, shoe covers, arc-proof 

glasses (face shield), safety shoes, hard hat and long-sleeve clothing to 
protect against the scattering of weld spatter that occurs during welding.

 

Caution: Electric Shock 

 If wearing gloves, be sure to always wear gloves with dry insulation 

properties. Do not wear gloves that are damaged or wet.

 

 

 
You can select a weld mode with the type of welding being performed. Select a 

weld mode by referring to the recommended modes in the table below.
