footwear is recommended when working outdoors.
• TAKE CARE OF CABLES: Never carry welding equipment by the cable and never pull the
cable to disconnect it from a socket. Keep cables away from heat, oil and sharp edges.
Replace damaged cables.
• DISCONNECT TOOLS: Disconnect welding equipment when not in use, before servicing,
and when changing accessories such as blades, bits and cutters.
• AVOID UNINTENTIONAL OPERATION: Do not carry plugged in welding equipment with
a nger on the switch. Be sure that the switch is o when plugging in.
• OUTDOOR USE EXTENSION CABLES: When electric power equipment is used outdoors,
only use extension cables marked as suitable for outdoor use.
• STAY ALERT: Watch what you are doing. Use common sense. Do not operate welders
when you are tired or under the inuence of alcohol or drugs.
• CHECK DAMAGED PARTS: Before using welding equipment, parts that are damaged
should be carefully checked to determine that they will operate properly and perform
their intended function. Any part that is damaged should be properly repaired
or replaced by an authorized service agent. Have defect switches replaced by an
authorised repair agent. Do not operate power equipment if it cannot be turned o and
on by the switch.
• REPAIR OF POWER EQUIPMENT BY EXPERTS: Power equipment is built in accordance
with relevant safety authority requirements. The repair of power equipment must only
be carried out by experts; non-expert repairs may cause considerable danger for the
user and void warranty.

WELD & CUT ARC / TIG WELDER AND PLASMA CUTTER
This is a current inverter generator (DC) for plasma cutting with pilot arc ignition and ARC/
TIG welding. This welder allows cutting of electrical conductive materials (metals and alloys),
through the use of gas, usually air, and it allows ARC welding with rutile, basic, stainless steel,
cast iron electrodes type and the TIG welding of the most metals except the aluminium
alloys.
Thanks to the inverter technology which allows achieving high performances while keeping
small size and weight, the machine is portable and easy to handle.
The machine is equipped with the following functions:
• “HOT START”, “ARC FORCE” and “ANTI STICK” (for more details please refer to the GENERAL
PART manual included in the package).
• “MEMORY PARAMETERS” - the microprocessor stores the welding parameters set during the
last use of the machine allowing automatic recovery each time.
• “VRD” – this function guarantees the voltage on the clamp is not dangerous for the end user.

INSTALLATION
Warning: Use all precautions required in the safety general manual before operating the
machine, reading carefully the risks associated with the welding and plasma cutter process.
The installation must be made by trained personnel in compliance to the standard IEC
60974-9 and the current and local legislation.
To lift the machine it must be used the handle positioned on the top of the product with
the machine in OFF position. The input voltage must match the voltage indicated on the
technical plate located on the product. The equipment shall only be used on a supply system
that is a single-phase, three-wire system with an earthed neutral. Use the machine on electric
system having supply features and power protection that are compatible with the current
required for its use. For more details see the information on the plate placed on the machine.
WELDER INFORMATION
The welding types selectable are:
PLASMA CUTTING - refer to Page 5 for Fig 1
• Connect the plug of the plasma torch to the socket of the machine (Fig 1, O).
• Connect the plug of the work clamp to the socket of the machine (Fig 1, P).
• Connect the power supply plug to the power outlet.
• Connect the air supply to the machine (Fig 1, R).
• Adjust the pressure of the air to 3 bar (Fig 1, S).
• Insert the power supply plug into the power outlet and turn on the machine.
• Set Plasma mode (Fig 1, I).
• Connect the work clamp to the work piece to be welded trying to establish a good point of
contact between the metal and the clamp, as close as possible to the area to be welded
• Adjust the cutting current (Fig 1, D).
• Start cutting.
ELECTRODE WELDING (ARC/MMA)
• Select the proper electrode polarity (direct or reverse) of the electrode (for more
information see the general part of the safety manual and the information on the electrode
packaging). Connect the plugs of the work clamp and the electrode holder to the sockets of
the machine (Fig 1, M, N) as function of the polarity, rotating the attack in order to ensure a
good grip.

VRD FUNCTION SELECTION
The voltage between the earth clamp and the electrode holder clamp may be dangerous for
the user. The VRD function prevents dangerous voltage value between clamps.
The needed voltage for welding is supplied only when the electrode makes contact with
the welding part. An acoustic buzzer advises the two phase’s transit. When the electrode is
removed from the welding part, the equipment returns to protective condition. When the
VRD device is on, the start of ARC may be dicult; therefore it is important to make contact
with the welding part to turn on the equipment and begin welding.
PROTECTION FROM OVERHEATING
The duty cycle is the fraction or percentage of a ten-minute cycle that a power source may
be used without overheating. For example, a welding machine with 150 amp - 30% duty
cycle can weld continuously at 150 amps for 3 minutes, and then must cool down during the
remaining 7 minutes to prevent overheating, with the ambient temperature of 40°C.
Using the machine with the proper duty cycle according to the selected current allows to
prevent overheating. In case of overheating of the machine the yellow LED (Fig 1, B) indicates
that the thermal protection is on, you can continue to use the machine when the LED is o.
MAINTENANCE
All maintenance and repairs must be carried out by an authorised repair agent. Any non-
authorised repairs will void warranty. Personnel in compliance to the norm (IEC 60974-4).
