WELDY miniwelder geo2 Bedienungsanleitung Seite 18

Anti-fall protection when working on areas where there is a danger of falling.
When welding on roof parapets and eaves, a stop fixture with horizontal guides (e.g. rail or rope
safety systems) must be secured to the carrying handle of the miniwelder as protection against
falling.
With respect to the safety chain, care must be taken to ensure that all of the safety elements (carabiner
hooks, ropes) have a minimum load-carrying capacity of 7 kN in every anticipatable direction. For the sus-
pension of the machine, it is mandatory to use clasp carabiners (Twist-Lock or screw types). All safety chain
connections must be installed and checked correctly in accordance with manufacturer specifications.
6.2 Starting the device
ƒ Insert the power plug, turn on the power by pressing the On/Off buttons for heating and drive (14 + 17) and
select temperature and speed, then take two narrow pieces of material for welding trials. Temperature selection
can be different for the same material at different ambient temperature and material thickness. To determine the
best welding result, adjust the speed to approximately 2 m/min, and then make different trial welds while slowly
adjusting the temperature from low to high. Keep safety chain taut at all times.
ƒ Evaluate welding parameters by carrying out tensile testing.
ƒ After temperature and speed have been determined, insert material to be welded between the two pressure rollers,
and engage the tension lever to start the welding process.
ƒ Check the welded seam. If required, correct the speed with the potentiometer drive (12).
ƒ When welding is completed, disengage the tension lever to prevent damage to the pressure rollers. Pressure
rollers should never run against each other without material between them.
