Operation
The welding machines Invert 130/40 and 130/60 are primary clocked inverters, suitable for manual arc welding with
coated stick electrodes and for direct current TIG welding (optional).
The electrode diameter and the required welding current are selected according to the material to be welded.

Commissioning
Caution:
This product is assembled with great care and thoroughly checked. All units undergo a computerised check before
leaving the factory. Please check your machine for transport damage after unpacking. In case such damage is
detected please notify your supplier immediately.
Ensure that mains voltage matches the machine's rated voltage as shown on its name plate. Connect to 230/240 V
AC circuit. The supply circuit need to be protected by a 16 amp time-lag fuse. Operation of other electrical equipment
on the same circuit while welding is limited.
Pure argon (of at least 99.998 % purity) is preferably used for TIG welding. Connection of the TIG torch to the gas
cylinder must be by means of a suitable pressure reducing device (max. 10 bar). The earth cable must have a
minimum lead cross section of 16 mm
