OPERATION
ATTENTION! The proper use of the welder may guarantee
it will work to satisfaction and can make the operation life
of the machine longer. When using the welder, please
assure there is an adequate input connection and ground
before connecting into the power supply.
WELDER OPERATION
Connect the welder power inlet cable and the output cable as
instructed in the operation instructions. Then, connect the welder
to the main power supply before turning on the switch.
CLEANING THE WORK PIECE BEFORE WELDING
Before carrying out any welding job make sure corrosion and spots
are eliminated in a range of
sides. However, if there is not excessive corrosion and there is no
big demand for weld seam, there is no need to clean the corrosion.
ELECTRODE REPLACEMENT
To enable the welding job, replace the electrode only when is
consumed 0.39" or 0.78" from the electrode holder.
CURRENT ADJUSTMENT
Current is adjusted using the triangular crank in the side panel. When
it is in the adequate direction, the current will be higher, when in the
opposite direction, the currant will be lower. The current value can
be watched in the current adjusting indicator window.
When the current indicator is close to the maximum or minimum
current value, please do not use a high setting because it causes
loss.
OBSERVATIONS: The electrode burns at high temperatures.
Do not use your hands to replace it. The replaced electrode
end shall be set into a metal container. Do not use the
electrode holder to hold the electrode covering.

SLAG REMOVAL
When the weld is finished use a special slag hammer to remove slag
from the weld seam.
OBSERVATIONS: The slag removal job can only be carried
out when the slag has cooled down and hardens. To prevent
being injured by the slag, there should never be people in
front of the work piece when you remove slag.
TRANSPORTATION AND STORAGE
ATTENTION! This welder is made with a box structure so it can be
firmly fixed in its base during transportation, complying with the
standard packaging.
When storing and transporting the welder, guard it against rain.
When loading, pay attention to the packaging. There shall not be
humidity, corrosive gasses and dust on the storage place. It shall
be kept dry and well ventilated. The allowed temperature ranges are
from
Relative humidity shall not exceed 90%.
-13 ºF, up to +131 ºF
After opening the packaging, it is suggested that the product will be
packed back according to the storage and future transportation
requirements. The users shall keep the packaging materials together
with the welder to use them during long distance transportation.
