ASSEMBLING THE UNIT / START-UP GUIDE
INSTALLATION
Make sure that the supply voltage is 115 or 230 volt and
make sure that the "
green-yellow wire " of the power
supply cable is connected to the ground or “earth” ter -
minal.
Electrical shock can result when contacting live
electrode or internal components
Electrical shock can result from absence of
grounding lug.
Welder must be connected to power source in
accordance with applicable electrical codes.
Do not touch electrode or internal compo-
nents without protection.
Disconnect power before servicing.
Do not remove the grounding lug in any elec-
trical plug.
Electrical shock can cause injury.
MMA (STICK) WELDING
• This welder is suitable for welding all types of elec -
trodes, with the exception of cellulosic (AWS 6010).
• Make sure that the switch
F
is in position 0, then con-
nect the welding cables, matching the polarity required
by the manufacturer of the electrodes you will be using.
VERY IMPORTANT: Connect the terminal of the ground-
ing cable to the workpiece, making sure that contact is
good to ensure smooth equipment operation and avoid
voltage dips with the workpiece.
• Do not touch the torch or electrode clamp simultane -
ously with the ground clamp.
• Turn the machine on using the switch
F
.
• Adjust the current based on the diameter of the elec -
trode, the welding position and the type of joint to be
made. Always remember to shut off the machine and re-
move the electrode from the clamp after welding.
TIG WELDING
• This welding machine is suitable for welding the fol -
lowing materials using the TIG procedure: stainless steel,
iron, copper, chrome moly brass + nickel.
• Make sure that the switch
F
is in position 0.
• Connect the ground cable connector to the positive
pole (+) of the welding machine, and the clamp to the
workpiece as close as possible to the welding point.
• Use the torch type (TIG130TA) and connect the power
connector to the negative pole (-) of the welding machine.
• Connect the switch cable plug to
H
the TIG torch con-
nector.
• Connect the gas hose to the outlet of the pressure regu -
lator, connected to an ARGON cylinder.
• Use a 2% thorium-covered tungsten electrode (red
strip), diameter 1.6 (1/16").
• Do not touch the electrode and ground clamp simulta -
neously.
• Turn the machine on using the switch
F
.
• Adjust the current, open the flow control knob on the
torch and adjust the flow rate at the flow meter.
• The flow of inert gas must be set to a value of 20-25
CFH. If you are using gas-lens type accessories, the gas
flow may be reduced.
The diameter of the ceramic nozzle must be 4 to 6 times
the diameter of the electrode.
Use D.I.N. 10protective glasses for up to 75A, and D.I.N.
11 from 75A up.
• Activate the torch switch and lock it into position by
sliding the switch forward.
• Strike the arc by contact using a firm, rapid stroke.
• Remember to shut off the machine, close the gas cyl
-
inder valve and release the torch switch when you have
finished welding.
