Particular danger
spots
(continued)
When hoisting the machines by crane, only use suitable manufacturer-
supplied lifting devices.
-
Attach the chains and/or ropes to
all
the hoisting points provided on the
suitable lifting device.
-
The chains and/or ropes must be at an angle which is as close to the
vertical as possible.
-
Remove the gas cylinder and the wirefeed unit (from MIG/MAG and TIG
units).
When hoisting the wirefeed unit by crane during welding, always use a
suitable, insulating suspension arrangement (MIG/MAG and TIG units).
If a machine is fitted with a carrying strap or carrying handle, remember that
this strap is ONLY to be used for lifting and carrying the machine by hand.
The carrying strap is NOT suitable for transporting the machine by crane,
fork-lift truck or by any other mechanical hoisting device.
Danger of colourless and odourless inert gas escaping unnoticed, when
using an adapter for the inert gas protection. Seal the adapter thread for the
inert gas connection using Teflon tape before assembly.
All lifting accessories (straps, handles, chains, etc.) used in connection with
the device or its components must be tested regularly (e.g. for mechanical
damage, corrosion or changes caused by other environmental factors).
The testing interval and scope of testing must comply with applicable natio-
nal standards and directives as a minimum.
Risk of scalding from accidental discharge of hot coolant. Before unplugging
the connectors for coolant forward flow and return flow, switch off the coo-
ling unit.
Observe the information on the coolant safety data sheet when handling
coolant. The coolant safety data sheet may be obtained from your service
centre or downloaded from the manufacturer’s website.
The following requirements with regard to shielding gas quality must be met
if the welding system is to operate in a correct and safe manner:
-
Size of solid matter particles <40µm
-
Pressure dew point <-20°C
-
Max. oil content <25mg/m³
Filters must be used if necessary.
NOTE!
There is an increased risk of soiling if ring mains are being
used
Factors affecting
welding results
Shielding-gas cylinders contain pressurized gas and may explode if they are
damaged. As shielding-gas cylinders are an integral part of the overall
welding outfit, they also have to be treated with great care.
Protect shielding-gas cylinders containing compressed gas from excessive
heat, mechanical impact, slag, naked flames, sparks and arcs.
Mount the shielding-gas cylinders in the vertical and fasten them in such a
way that they cannot fall over (i.e. as shown in the instruction manual).
