Use and maintenance of welding equipment may be dangerous. The user must
observe health and safety rules and regulations. Welding and cutting machines
may be used only by qualied personnel. Follow your local rules and regulations
on working with that type of devices and prevention of accidents.
Prior to starting your work remove all ammables from the welding area. Welding
inside tanks previously used as ammable liquids storage is forbidden. Place any
ammables in a safe location away from welding spatter.
Do not expose the device to rain, water vapour and do not spray water over it.
Do not start welding without proper eye protection equipment. Also protect other
people against generated radiation.
Use ventilation and lters in order to remove welding fumes from the work site.
Use individual lters if the ltering/ventilation system does not operate correctly or
is not available.
Stop your work immediately after nding damage to the power cords. Do not touch
the damaged cords. Prior a repair or maintenance disconnect the device from
power source. Never use the device with damaged power cords.
Keep a re extinguisher close to the welding location. After nishing welding check
work station against re hazard.
Never try to x a damaged gas reducer on your own. In case of malfunction repla-
ce the reducer to a fully functional one.
Electromagnetic interference
The device may inuence other devices sensitive to electro-
magnetic interference (robots, computers, etc.)
Always ensure that the devices within the welding work station are resistant to
interfe-
rence.
For the purpose of limiting interference, it is recommended to use as short welding
cables as possible and arranged in parallel.
Always work in a distance at least 100 m from other sensitive devices.
Always make sure that the installation is grounded.
If there still are interference with other devices,
properly shield the cables or use appropriate lters.

INTRODUCTION
Commissioning and normal operation are possible only after reading the carefully reading
following manual. The MIG/MAG, and MMA welding requires meeting the conditions
corresponding to electric arc welding and re regulations. Device operator should be equipped
with appropriate personal
health and safety equipment. It is necessary to use a set of personal protective equipment in
accordance with the provisions of Directive of the Council Directive No. 89/686/EC. Personal
protective equipment includes: welding mask, welding gloves, protective apron, leather shoes,
non-ammable welding clothing.
Despite the high technical standard of the device, the personnel should represent considerable
discipline in approach to health and safety requirements to protect against harmful and health
hazardous factors developed from welding technology.
OPERATING CONDITIONS
In order to ensure adequate service life and trouble-free operation it is recommended to:
• do not place or use this device on an inclined surface (of more than 15º),
• do not use the device for pipe defrosting,
• the device needs to be located in a place with free clean air circulation (to and from the fan
without obstacles). When connected to electrical network the device must not be covered (with,
for example, paper or cloth),
• minimize the amount of dirt and dust that can get into the device,
The device has an IP23S protection rating for housing and may be exposed to atmospheric
fallout and is capable of operating outdoors.
• do not use the device for welding tanks previously used for ammable substances storing.
GASES AND FUMES
Using MIG / MAG, TIG and MMA techniques produces harmful gases and fumes containing
ozone and hydrogen as well as oxides or metal particles. Therefore, the welding work station
should be tted with very good ventilation (dust and smoke extraction or airy location). Metal
surfaces intended for welding should be free from chemical contamination, especially
degreasers (solvents) that decompose during welding process and produce toxic gases.
Welding of galvanized, cadmium-coated or chromium-plated parts is permitted only when a
suction and ltering device is tted, and with introduction of fresh air to the welding work
station.
RADIATION
Ultraviolet emission radiated when welding is harmful to eyesight and skin. Therefore a welding
mask with protective lters is required. Welding work station should meet certain requirements
and include:
• adequate lighting system,
• xed or movable protection screens, governing bystanders against radiation e󰀨ects
(depending on requirements),
• location with wall colour providing appropriate for radiation absorption.

FIRE PROTECTION
Welding work station should be located at a safe distance from ammables placed especially
on the oor or walls. All ammables need re protection against hot metal drops. It is
recommended to t the work station with re blankets and re extinguishers.
PROTECTION AGAINST ELECTRIC SHOCK
It is unacceptable to connect the device to an improper installation or to an installation
with unveried zeroing e󰀩ciency. It is prohibited to use of device with shields removed or re-
move the external shields while the device is connected to electric network. It is not allowed to
work on a suspended device (e.g. using a crane or a gantry). Only authorized persons should
perform maintenance and repair works keeping it in compliance with the safety conditions
applicable to renovation equipment.
3. Maintenance (power supply and wire feeder)
ATTENTION: In order to carry out any repair or maintenance activity, it is recommended to
contact your nearest technical support of RYWAL-RHC (for list of company locations providing
technical support - see last page of this manual).
In the event of noticing any damage, the welder should stop working, disconnect the device
from power supply and report it to direct supervisor or appropriate service - RYWAL-RHC
technical support.
General maintenance (daily)
• check the condition of cables and connections, replace if necessary,
• remove spatter from the gas nozzle of the welding torch, spatter may transfer with the
shielding
gas to the welding arc, tend to disrupt the shielding gas ow and can e󰀨ect in a short circuit,
• check condition of welding torch, replace if necessary,
• check condition and operation of the cooling fan; keep the cooling air inlet and outlet openings
clean,
• keep the device clean.
Periodic maintenance (every 3 months at least)
Periodic maintenance frequency can be increased depending on the environment
in which the device is operating. Maintenance scope:
• using a stream of dry air (at low pressure) remove the dust from the outer parts of the casing
and from inside of the welding device,
• check and tighten all the screws,
• check the state of all electrical contacts and correct if necessary.

ATTENTION: Electrical network must be disconnected from the device before any maintenance
and service work. After each repair, perform respective check to ensure safe use.
Mandatory device checks
According to the Labor Code provisions: „All responsibility for the safe use of machinery
and equipment shall be borne by the owner.” This results in the obligation to perform periodic
and post-repair checks and inspections of equipment. Periodic tests are carried out at least
once a year (legal basis PN-EN ISO 17662 clause 4.2), and post-repair tests after each repair
that restored welding functionality (legal basis: PN-EN 60974-4 clause 4.6).
All above services re performed by the technical support of RYWAL-RHC.

Figure 3: The inuence of the roller groove on welding wire.
6.1 Selection of the wire feeder
In all Fanmig devices, two-groove rollers are used. Grooves are used for feeding wire with two
di󰀨erent diameters (e.g., 0.8 and 1.0 mm).
In order to change the diameter of the roller, pressure knob E1 must be released rst (accor-
ding to Fig. 2), so the pressure arm E2 will lift up. Then tighten the fastening bolt E5
and turn it 180 degrees. Alternatively replace it with the right wire for the given diameter.
Rolls intended for wire feeding must correspond to the diameter and workpiece of the wire to
be welded. Only such compatibility ensures equal wire feeding. Disturbances in wire feeding
lead to poor welding quality and wire deformation (see gure 3).
