3 Installation
The welding equipment is equipped with power voltage compensation device. It keeps the
machine work normally when power voltage fluctuating ±15% of rated voltage.
When using long cable, in order to reduce voltage drop, big section cable is suggested. If the
cable is too long, it will affect the performance of arcing and other system function, it is
suggested to use the recommend length.
Make sure the intake of the machine is not covered or blocked to avoid the malfunction of
the cooling system.
Use ground cable whose section no less than 6mm
method is to connect the grounded interface in the back to the earth device, or make sure
the earth end of power interface has been reliably and independently grounded. Both ways
can be used together for better security.
MIG 300GD Installation Procedures
Correct Installation of MIG
a)
Connect the gas cylinder with CO2 decompression flow mete tightly to CO2 mouth behind
the machine via air tube.
b)
Insert the swift plug of earth cable into socket at the front panel.
c)
Set the wire wheel with wire on the wheel axis, the wheel hole should be matched with the
wheel fixer.
d)
Choose wire slot according to wire size.
e)
Loosen the screw of wire-pressing wheel, pit the wire into slot via wire-lead tube, adjust the
wire-pressing wheel to keep wire fix from gliding, but strength should be suitable in case the
wire distorts and affects wire sending.
f)
Wire roll should turn clockwise rotation to let out wire, to prevent wire from gliding; wire is
usually set to the fixed hole on the wheel side. To prevent the bent wire from getting stuck,
please cut off this part of the wire.
g)
Put and tighten the torch on the output socket and put the wire into the torch by hand.
h)
Put the heater plug of the gas meter to the heater socket on the back panel.
Correct Installation of MMA
a)
Make sure cable with electrode holder and quick plug connected well. Connect the quick
plug to the socket "-" of the machine, and fasten it clockwise tightly.
Connect the quick plug at one end of the cable into the socket "+" of the machine, and
b)
fasten it clockwise, the other end clamps the workpiece.
c)
Please pay attention to the connecting terminal, DC welding machine has two connecting
