Handling And Transporting The Power Source; Selecting A Location; Connection And Preparation Of Equipment For Stick Welding; Connection And Preparation Of Equipment For Gas Tungsten Arc Welding (Tig) - CEMONT PUMA S 1400 Betriebs-Wartungs Und Sicherheitsanleitung

1. the 230V 50/60 Hz socket can supply sufficient power re-
quired for welding, see label on welder.
2. the socket supplies undistorted voltage RMS between 180
and 280 V.
3. the socket supplies peak voltage between 230 and 420 V.
4. the socket supplies alternate voltage with a frequency be-
tween 50 and 60 Hz.
IT IS ADVISABLE TO FOLLOW THE ABOVE INSTRUCTIONS
OTHERWISE THE WELDER COULD BE DAMAGED.
2.2 HANDLING AND TRANSPORTING THE POWER
SOURCE
OPERATOR SAFETY: WELDER'S HELMET - GLOWES -
SHOES WITH HIGH INSTEPS.
THE WELDING POWER SOURCE DO NOT WEIGHT MORE
THAN 25 KG AND CAN BE HANDLED BY THE OPERATOR.
READ WELL THE FOLLOWING PRECAUTIONS.
The machine is easy to lift, transport and handle, though the fol-
lowing procedures must always be observed:
1. The operations mentioned above can be operated by the
handle on the power source.
2. Always disconnect the power source and accessories from
main supply before lifting or handling operations.
3. Do not drag, pull or lift equipment by the cables.
2.3

SELECTING A LOCATION

SPECIAL INSTALLATION MAY BE REQUIRED WHERE GAS-
OLINE OR VOLATILE LIQUIDS ARE PRESENT. WHEN LO-
CATING EQUIPMENT, ENSURE THAT THE FOLLOWING
GUIDELINES ARE FOLLOWED:
1. The operator must have unobstructed access to controls and
equipment connections.
2. Use rating plate to determine input power needs.
3. Do not position equipment in confined, closed places. Venti-
lation of the power source is extremely important. Avoid
dusty or dirty locations, where dust or other objects could be
aspirated by the system.
4. Equipment (Including connecting leads) must not obstruct
corridors or work activities of other personnel.
5. Position the power source securely to avoid falling or over-
turning. Bear in mind the risk of falling of equipment situated
in overhead positions.
2.4 CONNECTION AND PREPARATION OF EQUIPMENT
FOR STICK WELDING.
TURN OFF WELDER BEFORE MAKING CONNECTIONS.
Connect all welding accessories securely to prevent power
loss. Carefully follow safety regulations described in SAFE-
TY RULES.
1. Fit the selected electrode to the electrode clamp.
2. Connect the earth lead connector to the negative (-) quick-
connection terminal (Ref. 6 - Picture 1 Page 4.) and the earth
clamp of the workpiece near the welding zone.
3. Connect the electrode clamp connector to the positive (+)
quick-connection terminal (Ref. 5 - Picture 1 Page 4.) .
CAUTION: MAKE THE ABOVE CONNECTION FOR DIRECT
POLARITY WELDING; FOR INVERSE POLARITY, INVERT
THE CONNECTION: EARTH LEAD CONNECTOR TO THE
QUICK-CONNECTION POSITIVE (+) TERMINAL AND THE
ELECTRODE HOLDER CLAMP CONNECTOR TO THE NEGA-
TIVE (-) TERMINAL.
4. Adjust welding current with ampere selector Ref. 2 - Picture
1 Page 4.) .
5. Press the illuminated switch to turn on the power source Ref.
1 - Picture 1 Page 4.) .
N.B. Serious damage to the equipment may result if the power
source is switched off during welding operations.

CONTROLS, POSITION AND FUNCTIONS

4 EN
The power source is fitted with an anti-sticking device that dis-
ables power if output short circuiting occurs or if the electrode
sticks, allowing it to be easily detached from the workpiece.
This device enters into operation when power is supplied to the
generator, even during the initial checking period, therefore any
load input or short circuit that occurs during this phase is treated
as a fault and will cause the output power to be disabled.
2.5 CONNECTION AND PREPARATION OF EQUIPMENT
FOR GAS TUNGSTEN ARC WELDING (TIG)
TURN OFF WELDER BEFORE MAKING CONNECTIONS.
Connect welding accessories securely to avoid power loss or
leakage of dangerous gases. Carefully follow the safety reg-
ulations.
1. Fit the required electrode and nozzle to the electrode holder
(check the protrusion and state of the electrode tip).
2. Connect the earth lead connector to the positive (+) quick-
connect terminal Ref. - Picture 1 Page 4.) and the earth
clamp to the workpiece near the welding zone.
3. Connect the torch lead connector to quick-connection nega-
tive (-) terminal Ref. 6 - Picture 1 Page 4.) .
4. Connect the torch gas hose to the gas cylinder outlet.
5. Press the illuminated switch to turn on the power source Ref.
1 - Picture 1 Page 4.) .
6. Check that there are no gas leaks.
7. Adjust welding current with ampere selector Ref. 2 - Picture
1 Page 4.) .
CHECK GAS DELIVERY; TURN GAS CYLINDER KNOB TO
REGULATE FLOW .
NB: The electric welding arc is struck by lightly touching the work-
piece with the electrode (Scratch start).
CAUTION: WHEN WORKING OUTDOORS OR IN WINDY CON-
DITIONS PROTECT THE FLOW OF SHIELDING GAS OR IT
MAY BE DISPERSED WITH RESULTING LACK OF PROTEC-
TION FOR THE WELD.

1. Connect the earth lead to the work piece to the negative ter-
minal (-) (Ref. 6 - Picture 1 Page 4.)
2. Connect the torch lead to the positive terminal (+) (Ref. 5 -
Picture 1 Page 4.).
ENSURE THAT THESE CONNECTIONS ARE WELL TIGHT-
ENED TO AVOID POWER LOSS AND OVERHEATING.
