machine is again ready for use.
4. WELDING MODE
4.1. CONTINUOUS WELDING
It is the mode in which the welding machine is likely to be used the most. In this mode, you have only to press the button of the
torch and the welding machine begins to work. To stop welding it is necessary releasing the torch button.
4.2. GAS PRESSURE
Gas pressure should normally be set to give a reading between 6 / 12 litres per minute on the flowmeter. Anyway, every
operator will find what suits him the most with his type of work and can make the necessary adjustment.
4.3. GAS – NO GAS WELDING MODE
4.3.1. Gas- torch clamp to positive terminal "+" and earth clamp to negative (-)
4.3.2. No gas- (only for preset models) earth clamp to positive terminal (+) and the torch clamp to negative (-).
4.4. MIG - MAG WELDING MODE
A) MIG = Metal Inert Gas
B) MAG = Metal Active Gas
These two modes are perfectly equivalent, the difference is given by the kind of gas you use.
In case A the gas employed is ARGON ( inert gas)
In case B the gas employed is CO2 ( active gas)
To weld alluminium alloys you need use ARGON (100%), to weld steel it is enough a compound of ARGON 80% and CO2
20%.
You can only use CO2 in case you will weld iron.
5. SPOOL WIRE AND TORCH INSTALLATION
5.1. SPOOLS INSTALLATION
WEMIG 100: on this model you can only use Ø 100 wire spools.
Models EASYCRAFT , WEMIG , NW you can use spools of Kg. 0,2 , Kg. 1 and Kg. 5. The welding machines are arranged with
hub for spool of Kg. 1. To fir the Kg. 5 spool, it is necessary to insert the supplied space and then to insert the Kg. 5 spool.
5.2. WIRE-FEEDER MOTOR
Make sure that the size of the groove in the feed roll corresponds to the welding wire size being used. The machines are
arranged with feed roll for Ø 0,6 and 0,8 wire, in case of Ø 1 mm welding wire, ask for the suitable feed roll. The feed roll has
the wire diameter stamped on its side.
The models EASYCRAFT are equipped with proper shagreneed rolls suitable for welding with flux cored wire without gas
protection. To weld with full wire with GAS protection you have to replace the roll of the wire feeder group which has V form for
the steel wire and U form for the aluminium wire.
If you intend to use the welder with gas protection you have to require such rolls and the pressure reducer to your retailer or to
the builder society.
5.3. FEEDING WIRE INTO THE WELDING TORCH
Cut the first 10 cm of wire and then check that there are no burrs or distortions at the cut end. Release the small wheel which
is connected to the pressure arm by unscrewing the pressure screw and pass the wire through the feed roll's groove and then
re-insert the wire into the guide.
At this point, make sure that the wire lies in the feed roll's groove in a natural line. Drop the pressure arm on the wire and swing
it back under the pressure screw. Pressure on the welding wire is regulated by turning the pressure screw, the correct
pressure being critically important to the smooth operation of the welding machine. The optimum pressure is the one which
ensures that the wire runs smoothly though allows the feed roll to slip in the event of a blockage in the torch.
It is possible to adjust the friction of the paddle hub. If the hub over-runs, then increase the friction pressure in order to always
have the spool wire drawn. On the contrary, if the friction pressure is too much, some tension can be released to obtain a
regular wire feeding.
5.4. TORCH CONNECTION
In models EASYCRAFT, WEMIG, NW , the torch is connected directly to the welding machine so it is ready for use. A probable
replacement of the torch must be done with care and if possible by a technician.
To replace contact tips, it is necessary to unscrew or to pull it. Replace tip, check that it corresponds with the wire size and
replace the gas shroud. For good wire feeding during welding operations, it is essential that the correct size parts are used
for each wire. Keep always clean the contact tip.
6. WELDING GUIDE
6.1. GENERAL RULE
When welding on the lowest output settings, it is necessary to keep the arc as short as possible.
This should be achieved by holding welding torch as close as possible and at an angle of approximately 60 degrees to the
workpiece. The arc length can be increased when welding on the highest settings, an arc length up to 20 mm can be enough
