2.3 Welding Protection
It is recommended to use a welding
helmet, conforming to the local relevant
Standards when electric arc welding.
Use a welding helmet in serviceable
condition with the correct filter lens
fitted as per Table 1.
2.4 User Responsibility
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 THERMAL DYNAMICS. Advice in this regard
can be obtained by contacting THERMAL DYNAMICS.
This equipment or any of its parts should not be altered from standard specification without prior
written approval of THERMAL DYNAMICS. The user of this equipment shall have the sole
responsibility for any malfunction which results from improper use or unauthorised modification
from standard specification, faulty maintenance, damage or improper repair by anyone other than
appropriately qualified persons approved by THERMAL DYNAMICS.
2.5 Duty Cycle
The rated duty cycle of a
welding Power Source is the
operating time it may be used
at its rated output current
without exceeding the
temperature limits of the
insulation of the component
parts. To explain the ten minute
duty cycle period the following
example is used. Suppose a
welding Power Source is
designed to operate at 30%
duty cycle, 250 amperes at 26
volts. This means that it has
been designed and built to provide the rated amperage (250A) at the rated load voltage (26V), for
3.0 minutes out of every 10 minute period (30% of 10 minutes is 3.0 minutes). During the other
7.0 minutes of the 10 minute period the Power Source must idle and be allowed to cool. The
thermal cut-out will operate if the duty cycle is exceeded.
