2.- SAFETY INSTRUCTIONS
CAREFULLY READ THE FOLLOWING INSTRUCTIONS.
-Make sure you read and understand the user's manual before
using or operating the equipment.
-Only use the genuine components of the manufacturer.
SYMBOL USAGE
DANGER! – Indicates a hazardous situation that, if
not avoided, will result in serious injury or death.
The possible dangers are shown in the attached
symbols or explained in the text.
Indicates a hazardous situation that, if not avoided,
may result in serious injury or death. The possible
dangers are explained in the text.
ARC WELDING DANGER
Only qualified users should install, operate,
maintain and repair this unit.
While operating, it must be kept away from people,
specially kids.
An ELECTRIC SHOCK can kill you.
Touching electric live-load pieces may cause severe burns or a fatal
electric shock. The electrode and work circuit become 'electrically
hot' whenever the machine output is on. Both the output and the
internal circuits are also 'electrically hot' when the machine is on.
While welding with automatic and semiautomatic equipment, the
wire, coil, the chassis that holds the feed rollers and all the metal
pieces touching the welding wire, are 'electrically hot'.
An incorrectly installed equipment or one without a proper grounding
connection is a very serious danger.
- Do not touch 'electrically hot' pieces.
- Use dry and well-insulated gloves with no gaps and whole-body
protection.
- You must isolate yourself from the work and the ground contact
by using carpets or big enough covers, made of non-conductive
materials in order to prevent any kind of physical contact with them.
- Do not use the alternate current output in humid areas, when
restricted motion, or if there is a fall risk.
- Use CA output ONLY if the welding procedure requires it.
- If the CA is required, use a remote control if available in your unit.
- Additional safety precautions are required when any of the following
dangerous electric conditions are present: in humid places or while
wearing wet clothes; in metal structures such as floor, grids or
scaffoldings; when the user is in tight positions as seated, kneeled,
lying down or when there is a high risk of having an unavoidable or
accidental contact with the ground or workpiece.
- Cut the input power or completely stop the unit before installing or
servicing it.
- Properly install and connect the unit to the ground according to the
manual and the national, state and local codes.
- Always verify the ground supply. Check and make sure the power
supply input ground wire is properly plugged to the disconnection
box ground terminal, or its plug is appropriately connected to
the ground-plugged output receptacle. While plugging output
connections, firstly plug the ground conductor and double check its
connections.
- Keep the seams and wires dry with no oil or grease stains. Protect
them from hot metal and sparks.
- Frequently inspect the current seam output for damages or bare
wire. Immediately replace the seam if it is damaged – A bare wire
could kill you.
- Turn off the equipment if it is not being used.
- Do not use wasted, damaged, small-sized or bad connected
cables.
- Do not wrap your body with the cables.
- If an earth clamp is needed at work, make the grounding connection
with a separated cable.
- Do not touch the electrode if you are already touching the grounding
circuit, work circuit or another electrode from a different equipment.
- Do not bring two electrode holders together while being connected
to different units at the same time or there will be a double current
open circuit.
- Use a well-maintained equipment. Repair or replace all the
damaged pieces. Maintain the unit according to the manual.
- Use safety straps to prevent the machine from falling if you are
working higher than the floor height.
- Keep all the panels and covers on their place.
- Put the clamp of the working cable with a good metal-to-metal
contact to the working cable or the work itself, close to the weld for
it to be practical.
- Save or isolate the clamp when it is not connected to the working
place so there will be no contact with any metal or any other ground
object.
- Isolate the grounding clamp when is not connected to the working
piece in order to avoid contact with any metal object.
HOT COMPONENTS can cause severe burns
- Do not touch hot components with bare hands. Use adequate
gloves.
- Allow some time for the equipment to cool itself before using it
again.
- To operate with hot components, use appropriate tools and use
welding-isolated heavy gloves and adequate clothes to prevent
burns.
SMOKE and GAS can be dangerous
Welding produces smoke and gas. Breathing those can be
dangerous for your health.
- Keep your head out of the smoke. Do not breath it.
- If you are indoors, make sure you ventilate the area and use forced
local ventilation before the arc to take the welding smoke and gas
away.
- If the ventilation is bad, use an approved air respirator.
- Make sure you READ and UNDERSTAND all the Material Safety
Data Sheets (MSDS's) and the manufacturer instructions about
metals, consumables, coatings, cleaners and degreasers.
- Work indoors ONLY if there is a proper ventilation or there is a
working air respirator. Always be next to a well-trained person.
Welding smoke and gas may move the air and decrease the oxygen
level, causing health damage or even death. Make sure the air you
breathe is safe.
