GLC 353/503/553 MC3 Operating instructions
Storage
- The machine should be stored indoors at a
temperature between -10
0 C and +40 0 C and
should be covered.
- If the coolant is not emptied, please ensure that
an anti-freeze agent is added. The coolant must
be disposed of and must not enter the main
drainage system.
Assembly
A complete machine comprises:
1.
Transistorized MIG/MAG pulsed arc
welding machine type
GLC 353/503MC3
2. Wire drive unit type Typ CK 98 A
3. Cable assembly, connectable
4. MIG/MAG welding torch
5. Standard accessories including:
Earth cable
Reducing valve with l/min.-scale
Tools
Set of fuses for power source
6. Options, if required
The individual components, MIG/MAG welding
machine, connectable cable assembly, wire drive
unit, gas cylinder and reducing valve have to be
assembled. The water hoses must not be
exchanged. The flow is marked blue!
Make sure cooling liquid is sufficiently filled.
All water-cooled machines are supplied with a 5 litre
container of ready-to-use mixture.
Power supply
The power supply must be installed by qualified
personnel only!
Please ensure that the mains voltage to be used is
identical to the operating voltage indicated on the
machine type plate.
According to the connection regulations the machine
has to be connected by means of a mains cable. The
power supply must be fused according to the
connection regulations. To ensure good welding
performance the cross section of the connection
cable must be adequate.
The phases L1, L2, L3 and PE are connected. The
neutral wire (N) remains free.
A correct conductor connection must be provided!
(VDE regulations).
Torch connection, earth cable
- The welding torch is connected to the central
connection, item 13, the water hoses to the
connections items 119 and 120 - they must not
be exchanged (insufficient cooling of the welding
torch). The flow is marked blue. The control line is
connected to the socket, item 109.
- The earth cable is connected to the current
connection, item 79, and locked by turning right.
- The gas cylinder is placed on the base plate, item
87, at the rear of the machine and is secured by a
chain, item 87/2, which is connected to the
holder, item 87/1.
Shielding gas, reducing valve
— The reducing valve is screwed onto the gas
cylinder and connected to the machine by means
of the gas hose, item 215. The gas quantity is
adjusted at the reducing valve. For this purpose
the machine must be switched on and the torch
button or key “gas manual”, item 103 must be
actuated at the wire drive unit.
— The normal gas quantity for Argon and mixed
gases is 8 - 15 l/min. and for CO
2
10 - 20 l/min.
— In general, carbon dioxide with a percentage
purity of 99.9 % is used for welding with
unalloyed or low alloy steels with a strength of 37
- 60 kgs. In Germany the gas cylinders have the
additional marking “S” (= Schweißzwecke -
welding purposes).
These steels can be welded with the gas mixture
(AR + CO
2
+ O
2
), high alloy steels, e.g. chrome
nickel steel require protective gas K2 ( Ar + 2%
CO
2
). Aluminium and other nonferrous metals
require pure Argon 99.9 %.
— The flow quantities indicated on the extraction
manometer depend upon choke setting, item
113/2 in front of the gas valve, item 111. This
choke has a nominal diameter of 0.6 mm. The
nominal diameter size 0.6 is clearly marked on
the litre scale of the extraction manometer. For
example, in the case of 4 bar, the flow quantity is
11.5 l/min.
— In the case of ring mains which operate at less
pressure, it is not possible to set a flow quantity
