Distribution network

All regular electrical devices without special circuits generate harmonic
currents into distribution network. High rates of harmonic current may cause
losses and disturbance to some equipment.

WARNING: This equipment does not comply with IEC 61000-3-12. If it is
connected to a public low voltage system, it is the responsibility of the
installer or user of the equipment to ensure, by consultation with the
distribution network operator if necessary, that the equipment may be
connected.

Cable connections

Connection to mains
The unit has a mains cable and a wall plug. You can find fuse and cable sizes
in the end of these instructions in Technical data.
Check the fuse size in Technical specifications. The plug may
NOTE!
be installed only by electrical contractors and installers specialised in
performing such operations.
If you use an extension power supply cord, its cross sectional area should
be at least as large as the supply voltage cable fitted to the machine. The
maximum length for the extension cable is 50 m.
The minimum power of a single-phase machine generator must be 3.5 kVA.
The recommended power is 7.0 kVA for using the machine at maximum
power.
Restrictions on generator type and power may apply in generator use. Fault-
free operation of a three-phase machine also requires a sufficiently high-
power generator. The power recommendation is more than 15 kVA.
earth return cable
Connect the earth return cable to the negative pole in MMA welding, and to
the positive pole in TIG welding.
Before you start welding, clean the work piece surface and fix the earth
return clamp to the work piece in order to create a closed and interference
free welding circuit.
Welding torch (tig)
The welding torch is used to supply shielding gas and electrical arc energy
to the work piece. Connect the TIG torch to the negative pole. Open the gas
valve of the TTM 15V TIG torch. The arc is ignited by touching the work piece
lightly with the TIG electrode (scratch ignition).
