GLC 353/503/553 MC3 Operating instructions
Shielding gases
The following gases are used for MIG/MAG welding:
Pure Argon, CO
2
, mixtures of Argon and CO
2
or
Argon, CO
2
and O
2
.
Flammable gases or gases which induce a chemical
reaction such as Acetylene, Propane, pure Hydro-
gen, pure Oxygen are prohibited.
Operating instructions
Transport
The machine must always be transported without
gas cylinder.
All cables must be wound up and put on the machine
before transport.
The machine can be moved on its wheels. When
using a fork lift truck, the forks must be applied
between the wheels. The machine must lie
crosswise on the truck.
Transport by means of a crane is also possible. If
jack rings are available all of them must be used
because of the carrying capacity and load
distribution. If there are no jack rings, two belts must
be used, pulled crosswise under the machine inside
the wheels.
Mounting area, floor requirement,
environment
- The machine should be installed on a horizontal,
flat surface, dust-free and well ventilated.
- The distance between other machines or
buildings should at least be 0.50 m (24 inches on
all sides, to aid ease of servicing.
- The cooling air entrance and exit grills must not
be restricted in any way
- The ambient temperature may vary from -10
0
C
to +40 0 C .
- The machine is protected to IP 23 which does
not permit use in the rain. If necessary, it should
be covered. In this case ensure that the cooling
air flow is not affected!
- The machine is marked "S", which means
approved for welding in environments with
increased electrical hazard; however, the power
source itself must not be installed there due to
the mains voltage of 400 V; only the welding
torch is permitted in such places.
General product description
Application possibilities and
restrictions
The transistorized MIG/MAG pulsed arc welding
machine type GLC 353/503 MC3 with wire drive unit
type CK 98 A is a welding machine with micro computer
control and a new air cooled power part with extremely
quick regulation due to particularl switch controller
technology. Outstanding welding features and low power
losses result from this. Aimed drop deposition with a
highest possible spatter reduction when welding with
Argon and Argon rich mixed gases with max. 20% CO
2
part. It can be welded pulse free with all arc kinds under
Argon, Argon O
2
mixed gases with multicomponent
mixed gases and under pure CO
2
.
Remarkable features of the wire drive units are the
precise rotation control (tacho control) and high motor
power (100 W) with four quadrant regulation (D).
2 + 2 roller system and 4 roller system guarantee safe,
slip-free and low abrasion wire transport. The adjustment
of the counter pressure is reproducible and comfortable
in handling.
The arc burns between wire and workpiece under
shielding gases (MAG = Metal active gas and MIG =
Metal inert gas procedure).
The wire electrode continuously unwound off the reel
until a reel is used up. The coil weight is 15 kgs with
steel and 4 ... 5 kgs with Aluminium.
The wire thickness and welding torches to be used
depend on material thickness and seam shape.
Power sources and wire feed are in separate housings
connected by a cable assembly. The complete system
is mounted on four rubber tyred wheels.
The machine is connected to a three phase current
supply. Direct current is available at the outlet.
The machine is set up for manual, mechanical and
robot MIG/MAG welding all metals. Manual d.c. TIG
welding with lift-arc ignition is possible.
The machine is suitable for welding all kind of flux cored
wire electrodes.
The machine is not suitable for thawing pipelines.
