Allen screw
Securing the wire spool retainer and adjustment of the spool brake
• Tighten the Allen screw (8 mm) in the clockwise direction to increase the braking effect.
Tighten spool brake only to the point where the wire spool no longer runs on when the trigger
"wire inching" is released! The wire spool must not jam!
If the Allen screw is now loosened by as much as it was previously tightened, a renewed
tightening of the pin reel will be necessary, see chapter "Fixing of the pin reel (adjustment of the
pretensioning)".
6.8
TIG welding
Warning – Risk from electrical current!
If welding is carried out alternately using different methods and if a welding torch and an
electrode holder remain connected to the machine, the open-circuit/welding voltage is applied
simultaneously on all cables. The torch and the electrode holder should therefore always be
placed on an insulated surface before starting work and during breaks.
Connection and welding leads (e.g. electrode holder, welding torch, workpiece lead, interfaces)
may only be connected when the machine is switched off.
Follow the safety instructions on the opening pages entitled “For Your Safety”!
We can only guarantee the perfect functioning of our machines when used with our range of
accessory components.
