FABRICATOR <strong>211i</strong> PROBLEMS/SERVICE<br />
8 Gas flow continues after<br />
the trigger switch has been<br />
released (MIG mode).<br />
9 Power indicator will not<br />
illuminate and welding arc<br />
cannot be established.<br />
10 TIG electrode melts when<br />
arc is struck.<br />
11 Arc flutters during TIG<br />
welding.<br />
Gas valve has jammed open<br />
due to impurities in the gas<br />
or the gas line.<br />
The mains supply voltage<br />
has exceeded voltage limits<br />
of the power source.<br />
TIG torch is connected to<br />
the (+) VE terminal.<br />
Tungsten electrode is too<br />
large for the welding current.<br />
Table 5-1: Power Source Problems<br />
5.02 Routine Service and Calibration Requirements<br />
WARNING<br />
Have an accredited Thermal<br />
Arc service provider repair or<br />
replace gas valve.<br />
Ensure that the mains supply<br />
voltage is within 230VAC ± 15%.<br />
Connect the TIG torch to the (-)<br />
VE terminal.<br />
Select the correct size of tungsten<br />
electrode. Refer to Table<br />
4-6.<br />
There are extremely dangerous voltage and power levels present inside this Inverter Power Source.<br />
Do not attempt to open or repair unless you are an accredited Thermal Arc Service Provider. Disconnect<br />
the Welding Power Source from the Mains Supply Voltage before disassembling.<br />
Routine Inspection, Testing & Maintenance<br />
The inspection and testing of the power source and associated accessories shall be carried out by a licensed<br />
electrician. This includes an insulation resistance test and an earthing test to ensure the integrity of the unit<br />
is compliant with Thermal Arc's original specifications.<br />
A. Testing Schedule<br />
1. For transportable equipment, at least once every 3 months; and<br />
2. For fixed equipment, at least once every 12 months.<br />
The owners of the equipment shall keep a suitable record of the periodic tests and a system of tagging,<br />
including the date of the most recent inspection.<br />
A transportable power source is deemed to be any equipment that is not permanently connected and fixed<br />
in the position in which it is operated.<br />
NOTE<br />
Please refer to local guidelines for further information.<br />
B. Insulation Resistance<br />
Minimum insulation resistance for in-service Thermal Arc Inverter Power Sources shall be measured at<br />
a voltage of 500V between the parts referred to in Table 5-2 below. Power sources that do not meet the<br />
insulation resistance requirements set out below shall be withdrawn from service and not returned until<br />
repairs have been performed such that the requirements outlined below are met.<br />
