technical provisions. Company ALFA IN a.s. accept no responsibility for damage
caused by improper use. Before commissioning please read carefully this
manual.
The machine complies with the appropriate CE mark.
For maintenance and repairs, use only original spare parts. There is of course a
complex of our services.
The SVAROG 420/520 HD synergic welding machine is a new generation of
multifunctional synergic welding machines of the ALFA IN brand.
The machine is designed for welding method MIG/MAG, MMA, TIG and the AIR
method. The SVAROG HD series is very variable and in addition to perfect
welding properties, is characterized by the following specifics:
1. Very high load 500 A at 60% (420 A at 100%) most other machines have
significantly lower power.
2. Ecological –efficiency higher than 89%. This means that at least 89% of the
energy from grid is converted into arc energy.
3. Remote control as standard –Thankstothe strongmagnet, youcan reliably
place it at a distance of up to 12m (the length of the extension cable is 6m).
You can easily place the panel on any ferromagnetic material, the side of the
welder or directly on the welded structure.

COOLING UNIT (only for water-cooled versions)
Recommendations for machines with detachable wire feed:
The cooling unit is ready to connect a TIG torch (front panel) and a MIG / MAG
torch (rear panel). When you welding with one method, disconnect the torch for
the other method. If both Torchs are connected, the cooling capacity for the
active Torch may be reduced.
WATER TORCH COOLING SYSTEM
1. The cooling unit is located at the bottom of the machine.
2. The pump seal in this ALFA IN welder is specially designed for ACL-10 fluid
(pink, order no. 4600, 5 l canister. Working area - ambient temperature -10 °
C to +40 ° C).
3. If another fluid is used, the cooling circuit may leak. A defect in the cooling
circuit when using a fluid other than ACL-10 cannot be covered under the
manufacturer's warranty. The fluid must not be mixed with any other type of
fluid.
4. Keep the coolant level in the coolant tank within the
permitted range (see illustration). The fluid level is
visually visible onthe front of thetank. Use the fluid
prescribed by the manufacturer.
If the error message "ERR 2‘ ‘" lights up during
operation, switch off the main switch. After turning
on the machine, perform a refrigeration unit test. If
the error persists, the cause of the fault must be
determined.
5. ACL-10 fluid is non-toxic. However, due to its operation in the pump, the
treated liquid is treated as hazardous waste. Do not burden the environment.
In the worst case, take it to the collection yard in the original canister. You
can find the safety data sheet on the line
https://www.alfain.eu/static/_dokumenty/1/2/8/8/0/4/Bezpecnostni-list-ACL-
10.pdf
6. Note.: When connecting a gas-cooled Torch, it is necessary to connect the
water quick couplings with the connecting hose of the liquid circuit, or switch
off the cooling unit !! Failure to observe this condition can damage the pump!

- 13 -
ALFA IN a.s. © www.alfain.eu
BLEEDING THE TORCH COOLING SYSTEM
1. After filling the empty Torch cooling system or replenishing the liquid after
extensive leakage and aeration, it is necessary to perform a complete circuit
venting.
2. Remove the coolant tank cap and connect the water quick couplings with the
fluid circuit connecting hose.
3. Run the cooling test for approx. 30 seconds.
4. Connect the Torch and run the cooling test for approx. 30 seconds.
If the error message "ERR 2" - low water pressure lights up after pressing the
Torch button, the procedure must be repeated.
