•
ARC welding produces fumes and gases and breathing these gases is hazardous to your health
Keep your head out of the fumes and do not breath the fumes while welding
Work only in a confined area if it has sufficient ventilation, or while wearing an air supplied
respirator. Fumes from welding can deplete the oxygen supply and can be harmful. Always be
sure there is ample breathing air
Read the MSDS sheets and the instructions from manufacturers for metals to be cut, coatings,
cleaners, and welding electrodes
Do not use the welder near hydrocarbon vapors coming from degreasing, cleaning, or spraying
operations. The heat and rays can react with solvent vapors to create a gas phosgene, a very toxic
gas, as well as other irritating gases
Do not weld coated metals, such as galvanized, lead, or cadmium plated steel. Before welding, all
plating must be removed. The area must be well ventilated or an air supplied hood must be used.
The coatings and chemicals when burned cause highly irritating and toxic fumes.
Do not cut containers with toxic, flammable, or reactive elements stored in them. They must be
emptied and properly prepared before cut. They must be cleaned and prepared to cut by the AWS
F4.1 guidelines for cutting containers or tubes

Sparks and hot metal fly out from the arc when welding, wear approved safety glasses with side
shields under approved helmets, wear proper body and hand protection, and wear flame resistant ear
plugs to keep sparks from entering the ears
CYLINDERS CAN EXPLODE IF DAMAGED
•
•
•
•
•
•
•
•
•
Gas cylinders contain gas under very high pressure. If damaged they can result in that cylinder exploding. Gas cylinders are a major part of metalworking and must be treated with care.

Operation
Powering Up the Welder
For most users, and 40Amp, 2 pole, 240V breaker will
work for most applications. If you find that you are
welding at the upper range of the rated output current
or if you find that you are overloading (tripping) the
breaker while welding, we suggest upsizing the breaker to a 50 Amp, 2 Pole, 240V breaker. Once the
breaker size is confirmed, plug the welder into the appropriate matching receptacle and turn the rotary power switch to the on position.
Current Selection
Crank
Welding Current Selection
Welding current selection is made by turning the crank
handle on the top of the welder. Turning clockwise
increases the amperage and turning counter clockwise
decreases the amperage. Amperage selected lines up
with the middle of the red indicator.
For the best results, the proper current and polarity
selection is essential. Check the electrode manufacturer’s recommendations for the proper settings.
Ground Clamp
The ground clamp must be connected so that a circuit
can be completed in order create the arc required for
welding. The ground clamp can be connected directly
to the work piece or can be connected to a base metal
the work piece is in contact with.
Electrode
To insert the electrode into the 7 position electrode
holder, squeeze the holder to open the jaw and put the
bare end of the electrode into the desired position in
the holder. Release the jaw.
Welding
Strike an arc and begin to weld.
Maintenance
Regular preventative maintenance is not required for
the ACDC300/200 other than keeping dust/dirt away
from the machine. If the louvers become dusty or
clogged, simply wipe the cover off to remove the dust/
dirt. These welders have no user serviceable parts.
Please contact KDAR for any necessary repairs or replacement parts.
Note: If you are new to welding, KDAR suggests you get instruction from a qualified welder prior to attempting to weld. Welding can be
dangerous if proper safety precautions are not
followed.
