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.

VIPER 2000
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.

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.

1. Power switch
The power switch disconnects the internal electronic circuitry from the welding supply voltage.
NOTE! The welding cables will still be live if the power source is switched on.
2. Power indicator
The power indicator will illuminate green when the power is switched on. If the power indicator illuminates
red then the welding input cables are incorrectly connected and should be reversed. No damage will be
caused if the power cables are incorrectly connected but the unit will not work.
3. Latch switch
The latch switch switches between the two different torch switch modes. In the off position the torch switch
must be pressed and held during welding. In the on position the torch switch may be pressed and released
during welding. To stop welding the torch switch must then be pressed and released again.
4. Flow meter
The ow meter gives an indication of gas ow and allows the gas ow rate to be adjusted from the front
panel of the unit.
NOTE! Do not over tighten the control knob as damage may occur to the ow-meter valve seat, note
that if the control knob is unscrewed too far air may enter the valve assembly and may cause porosity or
contamination of the weld.
