2.05 Description
Weldskill 100
This compact, portable, inverter welding machine
has infinitely adjustable welding current from 5 to
100 amps. It is capable of running 1.6mm, 2.0mm
and 2.5mm electrodes for a wide range of welding
applications. The unit also has a lift TIG function that
offers stable TIG welding characteristics when used
with a suitable TIG torch and shielding gas.

This equipment will perform as per the information
contained herein when installed, operated, maintained
and repaired in accordance with the instructions
provided. This equipment must be checked periodically.
Defective equipment (including welding leads) should
not be used. Parts that are broken, missing, plainly
worn, distorted or contaminated, should be replaced
immediately. Should such repairs or replacements
become necessary, it is recommended that such
repairs be carried out by appropriately qualified
persons approved by CIGWELD. Advice in this regard
can be obtained by contacting accredited CIGWELD
Distributor.

live electrical parts. Disconnect input
power conductors from de-energized
supply line before moving the welding
power source.
!

If using a fork lift vehicle, place and secure unit on a
proper skid before transporting.
2.09 Duty Cycle
The rated duty cycle of a Welding Power Source,
is a statement of the time it may be operated at its
rated welding current output without exceeding the
temperature limits of the insulation of the component
parts. To explain the 10 minute duty cycle period the
following example is used. Suppose a Welding Power
Source is designed to operate at a 15% duty cycle,
90 amperes at 23.6 volts. This means that it has been
designed and built to provide the rated amperage
(90A) for 1.5 minutes, i.e. arc welding time, out of
every 10 minute period (15% of 10 minutes is 1.5
minutes). During the other 8.5 minutes of the 10
minute period the Welding Power Source must idle
and allowed to cool.
