SAFETY INSTRUCTIONS 

THERMAL ARC 95 S

Safety Instructions 

1-3 

Manual 0-5086 

  WARNING

FLYING SPARKS AND HOT METAL can cause injury.

Chipping and grinding cause flying metal. As welds cool, 

they can throw off slag. 

1.  Wear  approved  face  shield  or  safety  goggles.  Side  shields 

recommended.

2.  Wear proper body protection to protect skin.

 WARNING

CYLINDERS can explode if damaged.

Shielding gas cylinders contain gas under high pressure. 

If damaged, a cylinder can explode. Since gas cylinders 

are normally part of the welding process, be sure to 

treat them carefully.

1.  Protect compressed gas cylinders from excessive heat, mechanical 

shocks, and arcs.

2.  Install and secure cylinders in an upright position by chaining 

them to a stationary support or equipment cylinder rack to prevent 

falling or tipping.

3.  Keep  cylinders  away  from  any  welding  or  other  electrical 

circuits.

4.  Never allow a welding electrode to touch any cylinder.

5.  Use only correct shielding gas cylinders, regulators, hoses, and 

fittings designed for the specific application; maintain them and 

associated parts in good condition.

6.  Turn face away from valve outlet when opening cylinder valve.

7.  Keep protective cap in place over valve except when cylinder is in 

use or connected for use.

8.  Read  and  follow  instructions  on  compressed  gas  cylinders, 

associated equipment, and CGA publication P-1 listed in Safety 

Standards.

!

 WARNING

Engines can be dangerous.

 WARNING

ENGINE EXHAUST GASES can kill.

Engines produce harmful exhaust gases.

1.  Use equipment outside in open, well-ventilated areas.

2.  If used in a closed area, vent engine exhaust outside and away 

from any building air intakes.

 WARNING

ENGINE FUEL can cause fire or explosion.

Engine fuel is highly flammable.

1.  Stop engine before checking or adding fuel.

2.  Do not add fuel while smoking or if unit is near any sparks or open 

flames.

3.  Allow engine to cool before fueling. If possible, check and add fuel 

to cold engine before beginning job.

4.  Do not overfill tank — allow room for fuel to expand.

5.  Do  not  spill  fuel.  If  fuel  is  spilled,  clean  up  before  starting 

engine.

 WARNING

MOVING PARTS can cause injury.

Moving parts, such as fans, rotors, and belts can cut fingers and hands 

and catch loose clothing.

1.  Keep  all  doors,  panels,  covers,  and  guards  closed  and 

securely in place.

2.  Stop engine before installing or connecting unit.

3.  Have  only  qualified  people  remove  guards  or  covers  for 

maintenance and troubleshooting as necessary.

4.  To prevent accidental starting during servicing, disconnect 

negative (-) battery cable from battery.

5.  Keep hands, hair, loose clothing, and tools away from moving 

parts.

6.  Reinstall panels or guards and close doors when servicing 

is finished and before starting engine.

 WARNING

SPARKS  can  cause  BATTERY  GASES  TO  EXPLODE; 

BATTERY ACID can burn eyes and skin.

Batteries contain acid and generate explosive gases.

1.  Always wear a face shield when working on a battery.

2.  Stop engine before disconnecting or connecting battery cables.

3.  Do not allow tools to cause sparks when working on a battery.

4.  Do not use welder to charge batteries or jump start vehicles.

5.  Observe correct polarity (+ and –) on batteries.
