Page 10: Environmental Conditions
The device is intended solely for the welding processes specified on the rating plate. Any use above and beyond this purpose is deemed improper. The manufacturer shall not be held liable for any damage arising from such usage. Proper use includes: carefully reading and following all the instructions given in the operating instructions studying and obeying all safety and danger notices carefully performing all stipulated inspection and maintenance work. -
Page 11: Protecting Yourself And Others
This may affect a number device types in terms of: Connection restrictions Criteria with regard to the maximum permissible mains impedance Criteria with regard to the minimum short-circuit power requirement at the interface with the public grid see "Technical data" In this case, the plant operator or the person using the device should check whether the device may be connected, where appropriate by discussing the matter with the power sup- ply company. -
Page 12: Danger From Flying Sparks
Fumes and hazardous gases must not be breathed in must be extracted from the working area using appropriate methods. Ensure an adequate supply of fresh air. Ensure that there is a ventilation rate of at least 20 m³ per hour at all times. Otherwise, a welding helmet with an air supply must be worn. -
Page 13: Meandering Welding Currents
Make sure that you and others are protected with an adequately insulated, dry base or cov- er for the earth or ground potential. This base or cover must extend over the entire area between the body and the earth or ground potential. All cables and leads must be secured, undamaged, insulated and adequately dimen- sioned. -
Page 14: Emc Device Classifications
Position the device with sufficient insulation against electrically conductive environments, e.g. Insulation against conductive floor or insulation to conductive racks. If distribution boards, twin-head mounts, etc., are being used, note the following: The elec- trode of the welding torch / electrode holder that is not used is also live. Make sure that the welding torch / electrode holder that is not used is kept sufficiently insulated. -
Page 15: Emf Measures
EMF measures Electromagnetic fields may pose as yet unknown risks to health: effects on the health of others in the vicinity, e.g. wearers of pacemakers and hearing aids wearers of pacemakers must seek advice from their doctor before approaching the de- vice or any welding that is in progress for safety reasons, keep distances between the welding cables and the welder's head/ torso as large as possible... -
Page 16: Factors Affecting Welding Results
If the wire-feed unit is attached to a crane holder during welding, always use a suitable, insulated wirefeeder hoisting attachment (MIG/MAG and TIG devices). If the device has a carrying strap or handle, this is intended solely for carrying by hand. The carrying strap is not to be used if transporting with a crane, counterbalanced lift truck or other mechanical hoist. -
Page 17: Danger From Escaping Shielding Gas
Danger from es- Risk of suffocation from the uncontrolled escape of shielding gas caping shielding Shielding gas is colourless and odourless and, in the event of a leak, can displace the ox- ygen in the ambient air. Ensure an adequate supply of fresh air with a ventilation rate of at least 20 m³/hour. Observe safety and maintenance instructions on the shielding gas cylinder or the main gas supply. -
Page 18: Commissioning, Maintenance And Repair
Always fasten the shielding gas cylinder securely and remove it beforehand if the device is to be transported by crane. Only the manufacturer's original coolant is suitable for use with our devices due to its prop- erties (electrical conductibility, anti-freeze agent, material compatibility, flammability, etc.). Only use suitable original coolant from the manufacturer. -
