Safety Guidelines
These general safety guides cover both arc welding machines and plasma cutting machines unless
otherwise noted. The equipment must only be used for the purpose it was designed for. Using it in any
other way could result in damage or injury and in breach of the safety rules. Only suitably trained and
competent persons should use the equipment. Operators should respect the safety of other persons.
Prevention against electric shock
The equipment should be installed by a qualified person and in accordance with current standards in
operation. It is the user’s responsibility to ensure that the equipment is connected to a suitable power
supply. Consult with your utility supplier if required. If earth grounding of the work piece is required,
ground it directly with a separate cable. Do not use the equipment with the covers removed. Do not
touch live electrical parts or parts which are electrically charged. Turn off all equipment when not in use.
Cables (both primary supply and welding) should be regularly checked for damage and overheating.
Do not use worn, damaged, under sized or poorly jointed cables. Ensure that you wear the correct
protective clothing, gloves, head and eye protection. Insulate yourself from work and ground using
dry insulating mats or covers big enough to prevent any physical contact with the work ground. Never
touch the electrode if you are in contact with the work ground, or another electrode from a different
machine.
Do not wrap cables over your body. Ensure that you take additional safety precautions when you are
welding in electrically hazardous conditions such as damp environments, wearing wet clothing, and
metal structures. Try to avoid welding in cramped or restricted positions. Ensure that the equipment
is well maintained. Repair or replace damaged or defective parts immediately. Carry out any regular
maintenance in accordance with the manufacturer’s instructions.
Safety against fumes and welding gases
Locate the equipment in a well-ventilated position. Keep your head out of the fumes. Do not breathe
the fumes. Ensure the welding zone is in a well-ventilated area. If this is not possible, provision should
be made for suitable fume extraction. If ventilation is poor, wear an approved respirator. Read and
understand the Material Safety Data Sheets (MSDS’s) and the manufacturer’s instructions for metals,
consumable, coatings, cleaners, and de-greasers. Do not weld in locations near any de-greasing,
cleaning, or spraying operations. Be aware that heat and rays of the arc can react with vapours to form
highly toxic and irritating gases. Do not weld on coated metals, unless the coating is removed from the
weld area, the area is well ventilated, and while wearing an air-supplied respirator. The coatings on many
metals can give off toxic fumes if welded.
Prevention against burns and radiation
Arc rays from the welding process produce intense, visible and invisible (ultraviolet and infrared) rays
that can burn eyes and skin. Wear an approved welding helmet fitted with a proper shade of filter lens
to protect your face and eyes when welding or watching. Wear approved safety glasses with side shields
under your helmet. Never use broken or faulty welding helmets. Always ensure there are adequate
protective screens or barriers to protect others from flash, glare and sparks from the welding area. Ensure
that there are adequate warnings that welding or cutting is taking place.
3
RT4000/5000

Wear suitable protective flame resistant clothing. The sparks and spatter from welding, hot work pieces,
and hot equipment can cause fires and burns. Welding on closed containers, such as tanks, drums, or
pipes, can cause them to explode. Accidental contact of electrode to metal objects can cause arcs,
explosion, overheating, or fire. Check and be sure the area is safe and clear of inflammable material
before carrying out any welding.
Protection against noise
Some welding and cutting operations may produce noise. Wear safety ear protection to protect your
hearing.
Protection from moving parts
When the machine is in operation, keep away from moving parts such as motors and fans. Moving
parts, such as the fan, may cut fingers and hands and snag garments. Protections and coverings may
be removed for maintenance and controls only by qualified personnel, after first disconnecting the
power supply cable. Replace the coverings and protections and close all doors when the intervention
is finished, and before starting the equipment. Take care to avoid getting fingers trapped when loading
and feeding wire during set up and operation. When feeding wire be careful to avoid pointing it at other
people or toward your body. Always ensure machine covers and protective devices are in operation.
Precautions against fire and explosion
Avoid causing fires due to sparks and hot waste or molten metal. Ensure that appropriate fire safety
devices are available near the cutting / welding area. Remove all flammable and combustible materials
from the cutting / welding zone and surrounding areas. Do not cut/weld fuel and lubricant containers,
even if empty. These must be carefully cleaned before they can be cut/welded. Always allow the cut/
welded material to cool before touching it or placing it in contact with combustible or flammable
material. Do not work in atmospheres with high concentrations of combustible fumes, flammable gases
and dust. Always check the work area half an hour after cutting to make sure that no fires have begun.
Risks due to magnetic fields
The magnetic fields created by high currents may affect the operation of pacemakers or electronically
controlled medical equipment. Wearers of vital electronic equipment should consult their physician
before beginning any arc welding, cutting, gouging or spot welding operations. Do not go near welding
equipment with any sensitive electronic equipment as the magnetic fields may cause damage.
RF Declaration
Equipment that complies with directive 2004/108/EC concerning electromagnetic compatibility (EMC)
and the technical requirements of EN60974-10 is designed for use in industrial buildings and not those
for domestic use where electricity is provided via the low voltage public distribution system. Difficulties
may arise in assuring class A electromagnetic compatibility for systems installed in domestic locations
due to conducted and radiated emissions. In the case of electromagnetic problems, it is the
responsibility of the user to resolve the situation. It may be necessary to shield the equipment and fit
suitable filters on the mains supply.
4RT4000/5000

5
LF Declaration
Consult the data plate on the equipment for the power supply requirements. Due to the elevated
absorbency of the primary current from the power supply network, high power systems affect the
quality of power provided by the network. Consequently, connection restrictions or maximum
impedance requirements permitted by the network at the public network connection point must be
applied to these systems. In this case the installer or the user is responsible for ensuring the equipment
can be connected, consulting the electricity provider if necessary.
Materials and their disposal
The equipment is manufactured with materials, which do not contain any toxic or poisonous
materials dangerous to the operator. When the equipment is scrapped, it should be dismantled
separating components according to the type of materials. Do not dispose of the equipment with
normal waste. The European Directive 2002/96/EC on Waste Electrical and Electronic Equipment states
the electrical equipment that has reached its end of life must be collected separately and returned to an
environmentally compatible recycling facility.
Handling of compressed gas cylinders and regulators
All cylinders and pressure regulators used in welding operations should be handled with care.
Never allow the electrode, electrode holder or any other electrically “hot” parts to touch a cylinder.
Keep your head and face away from the cylinder valve outlet when opening the cylinder valve.
Always secure the cylinder safely. Never deface or alter any cylinder.
The following signs and explanations are to remind the user of the potential
risks involved and the dangers of misuse or mistreatment of the welding
machine.
!
RUNNING PARTS MAY BE DANGEROUS!
Keep away from running components,
including the fan.
BE AWARE OF SPARKS AND SPATTER
Wear protective clothing, such as leather
gloves, Flame retardant overalls, boots and
eyewear.
DO NOT TOUCH THERMAL COMPONENTS!
Thermal components may cause severe burns
when in contact with unprotected skin.
ELECTRIC SHOCKS CAN KILL!
Never touch electrical parts. Keep the
equipment in good condition, replace
damaged parts, undertake regular
maintenance according to the instructions.

Unpacking
Check the packaging for any signs of damage. Carefully remove the machine and retain the packaging
until the installation is complete.
Positioning of the machine
Place the machine on a rm, dry and level surface. Where possible, do not allow dust or other impurities
to enter the machines cooling air ow. Preferably site the machine above oor level; for example on a
suitable carriage unit.
Notes for positioning the machine
• Make sure there is at least 20cm clearance at the front, rear and sides of the machine to allow good
circulation of the cooling air.
•Ensure that the machine is positioned in such a way that particles created by grinding and cutting
operations do not enter the machine.
NOTE! Damage caused by metal particles and water entering the machine will not be covered under warranty.
WARNING! All electric shocks are potentially fatal, a competent electrician should under-take the tting
of the mains plug.
Connecting to mains supply
Assure that the mains supply is of the correct voltage and current
capability for the machine. Make sure that the mains cable and
any extension cables used are of sufficient current carrying
capacity.
Check the mains plug and socket (if tted) are in good condition.
If the machine is wired directly to the mains supply then an
isolator switch must be tted.
Primary cable length
Long cable lengths may reduce the performance of the machine, the welding arc may become
unstable, especially at higher currents. Ensure the mains cable is not coiled up during welding as this will
reduce the input voltage to the machine and may cause overheating and degradation of the cable.
Setting supply voltage tapping
•To enable the setting of the supply voltage tapping, the front panel display cover of the RT4000/RT5000
has to be removed.
•The photograph above shows the voltage tap-ping set to 415V, with the red wire from the fuse holder
connected to the 415 terminal.
•This connector can be moved to the required voltage terminal to select the desired input voltage.

MMA Welding
• For straight polarity welding, connect the electrode holder to the positive weld terminal and the earth return
lead to the negative weld terminal. For reverse polarity welding, reverse these connections.
• Turn the mains switch to the on position, the digital will light and after a 4 second delay the machine is ready
to weld.
• Adjust the current control to the recommended setting for the size and type of welding electrode to be used.
• Adjust the Arc Force control to your personal preference for the size and type of welding electrode to be used.
The RT4000/RT5000 is suitable for welding all types of electrodes within the current rating of the machine (see
Technical Data)
The RT4000/RT5000 should never be used with arc-air gouging or cutting electrodes.
MMA Welding with remote control
WARNING! All electric shocks are potentially fatal, a competent electrician should carry out the tting of the
mains plug.
• Make sure that the mains supply is of the correct voltage and current capability for the machine.
• Make sure that any extension cables used are of sufficient current carrying capacity.
• Make sure that the mains plug and socket (if tted) are in good condition and are of the correct current
carrying capacity. If the machine is wired directly to the mains supply then an isolator switch must be tted.
Note! See the technical specications page forcorrect supply information
TIG Welding
• Switch the mode switch to‘TIG’and select either 2T or 4T torch mode.
• Connect the TIG torch power cable to the negative output connector.
• Connect the TIG torch gas connector to the gas quick coupler.
• Connect the welding ground to the positive output connector.
• Connect a supply of pure argon to the connector at the rear of the machine.
• Turn the mains switch on the RT4000/RT5000 to the on position, the digital display will indicate current
when the machine is ready for use.
• Adjust the slope, current and post gas controls to the required settings, you are now ready to weld.
3. Operation
RT4000/5000

14
Most problems with the RT4000/RT5000 can be over-come by following the procedures below.
No Digital Display on switch on
• Check that the machine is attached to a work-ing mains supply that it is correctly plugged in and any
isolator switches are closed.
• Check the condition of the 3.15A fuse on the rear panel of the machine and replace if nec-essary.
NOTE! make sure the fuse is replaced with one of the correct type and rating. It should be a 32 x 6.3mm
(1¼”x ¼”) ceramic bodied type with a rating of 3.15A‘slow blow’
Have a competent electrician check that there are no mains fuses or overload devices inter-rupted, that
the mains plug is tted correctly and that there are no loose wires or connec-tions, check that there are
no breaks in the mains cable.
Digital display lit but no output
Make sure that the display is not reading‘HOT’, if it is, it means that the RT4000/RT5000 has over-heated,
normally by exceeding its ’Duty Cycle’, and the power stages of the machine have been shut down.
In this case, leave the ma-chine switched on until it has cooled down, if you turn the machine off, the
cooling fans will be turned off and the cooling down period will be lengthened considerably.
NOTE! If the RT4000/RT5000 is overheating on a regular basis or at current settings below the maxi-
mum, this would usually indicate that the inside of the machine is choked with dust and therefore not
being cooled correctly. For information about cleaning the dust out of the RT4000/RT5000 please refer
to the relevant part of section 5.3.2, the three monthly service schedule.
4. Fault nding
RT4000/5000

15
MMA
If problems with theRT4000/RT5000’s operation while welding are experienced, rst refer to the
information in the installation section and paragraphs in the operating section and the fault nding
procedure earlier in this section.
• Most problems with MMA welding are the result of not setting the correct welding parameters for the
welding rod being used. All welding rod packets have information on them in symbolic format , giving
suitable current range, polarity and type of weld (normally called ‘position’). If you are in doubt about
what these symbols mean, ask your welding rod supplier to explain them. Choose an initial current
setting towards the middle of the quoted range and if neces-sary practice on a piece of scrap the same
thickness as the job to be welded.
TIG
• If problems are experienced whilst TIG welding, please consult the fault nding and maintenance
section in the TIG unit instruction manual.
The common problems with TIG welding are poor striking, porosity and poor appearance of the weld.
If you are experiencing any problems with TIG welding follow the check list below, this will cure most
problems.
• If the unit is suffering from poor striking, check that all power leads are connected properly, check that
there is sufficient gas ow and that the correct gas is being used, check that the earth clamp is making a
good connection to the work-piece.
• If there is porosity in the weld or the nal weld is of poor appearance, check that there is suffi-cient
gas ow and that the correct gas is being used, check the condition of the TIG torch, par-ticularly the
gas hose. Make sure that the collet or gas lens in the torch head is not blocked in anyway. Check all
gas connections are secure and that there are no leaks, use a leak detect-ing spray on all connections if
necessary.
Any welding problems not covered above must be brought to the attention of a qualied welding
engineer, if the problem still persists have the RT4000/RT5000 checked by a trained Newarc service
engineer.

5. Maintenance
Note!
All Electric shocks are potentially fatal, switch off the machine and unplug from the
mains supply before carrying out any maintenance work.
It is very important that the RT4000/RT5000 is regularly maintained. The amount of use and the working
environment must be taken into account when scheduling the maintenance periods.
Careful use and regular preventative maintenance will prolong the life of the machine and ensure trou-
ble free operation.
Weekly
• Clean the exterior of the machine.
• Inspect the machines exterior for obvious signs of damage.
• Check the condition of the welding cable, earth clamp and welding output connectors for damage
and any sign of over-heating
• Check the condition of the mains cable and plug.
Three monthly
As per the weekly schedule, plus:
• Remove the lid from the machine and remove the build up of dust and debris from inside the machine
using, either, compressed air at low pressure or an industrial type vacuum cleaner.
• Make a thorough visual inspection of the interior of the machine, look particularly for pieces of welding
wire that may have got through the cooling air intakes.
• Check the condition of the mains input connector, look for loose terminal block screws and make sure
the sheath of the mains cable is still clamped securely in the combined cable en-try/clamp. Make sure
the earth wire is still securely fastened to the earth stud.
• Check the condition of the welding output connectors, look for any signs of discoloration. This could
be an indication of overheating and can be a cause of welding set failure.
Annually
As per the three monthly schedule, plus:
• The machines calibration should be checked, if necessary have the machine re-calibrated by a Newarc
trained technician.n.
