In addition to the above tests and specifically in relation to the VRD fitted to this machine, the
following periodic tests should also be conducted by an accredited CIGWELD service agent.
Description AS3195 & IEC 60974-1 Requirements
VRD Open Circuit Voltage Less than 20V; at Vin=240V or 415V
VRD Turn ON Resistance Less than 200 ohms
VRD Turn OFF Time Less than 0.3 seconds
If this equipment is used in a hazardous location or environments with a high risk of electrocution
then the above tests should be carried out prior to entering this location.
8. Installation Recommendations
8.1 Environment
The Transtig 200Pi, 250Pi, 300Pi is designed for use in hazardous environments when the VRD is
TURNED ON.
a) Examples of environments with increased hazardous environments are -
i) In locations in which freedom of movement is restricted, so that the operator is
forced to perform the work in a cramped (kneeling, sitting or lying) position with
physical contact with conductive parts;
ii) In locations which are fully or partially limited by conductive elements, and in which
there is a high risk of unavoidable or accidental contact by the operator, or
iii) In wet or damp hot locations where humidity or perspiration considerable reduces the
skin resistance of the human body and the insulation properties of accessories.
b) Environments with hazardous environments do not include places where electrically
conductive parts in the near vicinity of the operator, which can cause increased hazard,
have been insulated.
8.2 Location
Be sure to locate the welder according to the following guidelines:
a) In areas, free from moisture and dust. b) Ambient temperature between 0°C to 40°C.
c) In areas, free from oil, steam and
corrosive gases.
d) In areas, not subjected to abnormal vibration
or shock.
e) In areas, not exposed to direct sunlight
or rain.
f) Place at a distance of 300mm or more from
walls or similar that could restrict natural air
flow for cooling.
8.3 Ventilation
Since the inhalation of welding fumes can be harmful, ensure that the welding area is effectively
ventilated.
8.4 Mains Supply Voltage Requirements
The Mains supply voltage should be within ± 10% of the rated Mains supply voltage. Too low a
voltage may cause the fuse or circuit breaker to rupture due to the increased primary current. Too
high a supply voltage will cause the Power Source components to fail.
