5.7 MMA welding
When replacing spent or new stick electrodes, always switch off the machine at the main
switch.
Always use insulated tongs to remove used stick electrodes or to move welded workpieces.
Always put the electrode holder down when insulated.
5.7.1 Electrode holder
•
Insert cable plug of the electrode holder into the welding current socket (C1 "+" or D1 "-"
)
and
lock by turning to the right.
The polarity depends on the instructions from the electrode manufacturer given on the
electrode packaging.
Clamp stick electrode into electrode holder. Caution: Risk of injury from crushing!
Always put down stick electrode holder in an insulated position.
5.7.2 Workpiece lead
•
Insert cable plug of the workpiece lead into the welding current socket (C1 "+" or D1 "-"
)
and
lock by turning to the right.
The polarity depends on the instructions from the electrode manufacturer given on the
electrode packaging.
5.8 TIG welding
We can only guarantee the perfect functioning of our machines when used with our range of
welding torches.
Standard TIG welding torches with shielded torch trigger control leads should not be
connected (see torch operation instructions)!
Follow the safety instructions on the opening pages entitled "For your safety".
Before welding ensure that all coolant hoses are connected.
5.8.1 Welding torch, general
Always put down welding torch when insulated.
•
Fit tungsten electrode and gas nozzle onto the welding torch
(observe current load, see torch operating instructions).
•
Engage the rapid-action closure nipple of the TIG torch in the rapid-action closure coupling for
the coolant supply (blue) and return (red) lines of the cooling unit (only for water-cooled
torches).
•
If a gas-cooled torch is used on a water cooled unit, either a tube bridge must be connected
between the water supply and the cooling unit return to prevent the coolant pump from running
hot, or the control lead of the cooling unit must be removed from the welding machine.
•
Insert the welding current plug into socket "-" (E1) and lock by turning to the right.
•
Screw shielding gas connection of the welding torch tightly on to the connection nipple G¼ (F1
)
