Maintenance work, intervals 

6.3.1 

Daily maintenance tasks 

Visual inspection 
•  Mains supply lead and its strain relief 
•  Gas cylinder securing elements 
•  Check hose package and power connections for exterior damage and replace or have repaired by 

specialist staff as necessary! 

•  Gas tubes and their switching equipment (solenoid valve) 
•  Check that all connections and wearing parts are hand-tight and tighten if necessary. 
•  Check correct mounting of the wire spool. 
•  Wheels and their securing elements 
•  Transport elements (strap, lifting lugs, handle) 
•  Other, general condition 

 

Functional test 
•  Operating, message, safety and adjustment devices (Functional test) 
•  Welding current cables (check that they are fitted correctly and secured) 
•  Gas tubes and their switching equipment (solenoid valve) 
•  Gas cylinder securing elements 
•  Check correct mounting of the wire spool. 
•  Check that all screw and plug connections and replaceable parts are secured correctly, tighten if 

necessary. 

•  Remove any spatter. 
•  Clean the wire feed rollers on a regular basis (depending on the degree of soiling). 

 

6.3.2 

Monthly maintenance tasks 

Visual inspection 
•  Casing damage (front, rear and side walls) 
•  Wheels and their securing elements 
•  Transport elements (strap, lifting lugs, handle) 
•  Check coolant tubes and their connections for impurities 

 

Functional test 
•  Selector switches, command devices, emergency stop devices, voltage reducing devices, message 

and control lamps 

•  Check that the wire guide elements (inlet nipple, wire guide tube) are fitted securely. 
•  Check coolant tubes and their connections for impurities 
•  Check and clean the welding torch. Deposits in the torch can cause short circuits and have a negative 

impact on the welding result, ultimately causing damage to the torch. 

 

6.3.3 

Annual test (inspection and testing during operation) 

A periodic test according to IEC 60974-4 "Periodic inspection and test" has to be carried out. In addition 
to the regulations on testing given here, the relevant local laws and regulations must also be observed.
