ADJUSTMENT FUNCTIONS
1. Mains switch and switch between AC and
DC.
When the machine is turned on, this is
indicated by light in the ammeter, and a short
opening of the solenoid valve to purge gas
hose.
2. Welding cable sockets.
3. Quick release connection for shielding gas.
4. Multiplug for the connection of TIG torch
control wire.
5. Quick release connection for water flow to
water cooled TIG torch.
6. Quick release connection for recirculation of
water from water cooled TIG torch.
7. Safety control.
Control lamp is turned on if there is more than
9 V AC on the welding cable sockets. This
lamp should not light when not welding.
The construction of the MTE machines
ensures that the open circuit voltage is always
a DC voltage with a ripple voltage less than 5
per cent, also for AC welding.
If the lamp lights when not welding, the
machine does not meet the safety regulations
for welding under special conditions as
described in the power current regulations.
It is usual for the lamp to light during AC
welding.
