GENERAL DESCRIPTION
The MTE machines are single-phase, thyristor
controlled AC/DC welding machines for manual
electrode welding with all types of electrodes as well
as for manual and automatic TIG welding.
The special construction of the power source with a
bifilar-wound welding inductor provides square
waved welding current when welding AC. Contrary to
a conventional welding machine with sine waves,
square waves have the advantage that the current
tops are reduced to ensure a softer arc and less load
on the electrode when TIG welding. The special
construction of the machine allows an adjustment of
the relation between the positive and the negative
half-wave to obtain the correct relation between
cleaning and penetration, that is, AC balance.
The square wave technique in conjunction with the
balance adjustment ensure a stable arc and a better
penetration as well as a reduced electrode wastage.
The all-electronic control unit ensures that the actual
welding current corresponds to the set value.
When electrode welding an "anti-sticking" device
prevents electrodes "sticking" to the workpiece as
the current is reduced to 5 A in case of short-circuit.
A watercooling unit type CTU 3000 (part no:
76118013) can be mounted.
