USE AND OPERATION

The ASIST equipment and machines are designed for
domestic
or hobby use only.
The manufacturer and the importer do not recommend
to use this equipment under extreme conditions and at
high loads. Any other additional requirements must be
agreed upon by the manufacturer and the buyer.
Please remember that our equipment has not been
designed for commercial, trade or industrial use ac-
cording to its purpose. We accept no liability if the
equipment is used in commercial, trade or industrial
companies and during similar activities.
INSTALLATION
The electric energy is induced by the equipment with
voltage compensation of the electric energy.
Check if the electric connection is secured in accor-
dance with the respective nameplate. The equipment
is dimensioned for compensation of mains voltage sur-
ges. Surges of ± 15% cause changes in the welding
current by
± 3%. Make sure not to have venting slots on the front
panel blocked and to have them free also during use
of the equipment. This way you can prevent harmful
overheating of the equipment. If a long cable is used,
to avoid voltage drops, a bigger cable diameter is re-
commended. If the cable is too long, it may affect the
power performance. Use an extension cable with len-
gth up to 10 m and diameter of at least 1.5 mm2 , from
10 m to 20 m with diameter of at least 2.5 mm2 , from
20 m to 50 m with diameter of at least 4 mm2 .
Make sure that the air inlet into the equipment is not
blocked or covered so that the ventilation could suffi-
ciently fulfill its function.
To prevent the risk of electric shock, the inverter must
be properly grounded. Grounding must be carried out
by a qualified person.
Manual metal arc welding (MMA) Strictly observe res-
pective safety regulations. Connect the welding acces-
sories properly to prevent energy losses.
1. Insert the respective electrode into clamping jaws.
2. Insert the grounding cable connection into the nega-
tive clamp (-) with a quick-closing device, and connect
it into the grounding clamp close to the welding spot.
3. Insert the cable connection with an electrode holder
into the positive clamp (+) with a quick-closing device.
4. A DC one-way welding equipment has two connec-
ting options: positive and negative.
To get a reverse polarity, the quick couplers must be
transposed. Namely, the grounding cable coupler into
the positive clamp (+) and the electrode holder coupler
into the negative clamp (-).
5. Set the welding current intensity using the ampere
switch.
6. Turn the mains switch to "I".
7. The inverter is ready for use.
WARNING. Do not turn the inverter off during welding.
