Re-radiation from Unearthed Metallic Objects
A major factor contributing to interference is re-radiation from unearthed metallic objects
close to the welding leads.
Remedy: Effective grounding of such objects will prevent re-radiation in most cases.
3.4 LOCATION
The location of the 200AP unit should be in accordance to the following guidelines:
•
In areas, free from moisture and dust.
•
In areas, free from oil, steam and corrosive gases.
•
In areas, not exposed to direct sunlight or rain.
•
Ambient temperature between 0 degrees C to 40 degrees C.
•
In areas, not subjected to abnormal vibration or shock.
•
Place at a distance of 12” (304.79mm) or more from walls or similar that could restrict natural
airflow for cooling.
3.5 ELECTRICAL INPUT CONNECTIONS & REQUIREMENTS
The 200AP operates from a single or three-phase 50/60 Hz, AC power supply. The
input voltage must match one of the electrical input voltages shown on the input data label on
the unit nameplate. Contact the local electric utility for information about the type of electrical
service available, how proper connections should be made, and any inspection required.
3.5.1 INPUT POWER
The 200AP unit incorporate an INRUSH circuit and input voltage sensing circuit.
When the MAIN CIRCUIT SWITCH is turned on, the inrush circuit provides a pre-charging
of the input capacitors. SCR’s in the Power Control Assembly (PCA) will turn on after the
input capacitors have charged to full operating voltage (approximately 5 seconds).
NOTE:
Damage to the PCA could occur if 575VAC or higher is applied.
The 200AP unit is designed for use with a generator as an input power source. As a
general rule, depending on the type of generator used, the minimum generator capacity
should be twice the maximum rating of the welder.
