STEALTH DIGI-ARC 160LT
6. INSTALLATION & ADJUSTMENT
Note: Please follow steps in strict accordance with installation instructions!
Electrical connection must be disconnected after power is switched off!
Equipment protection level is IP23. Do not use in the rain!
6.1 Installation
6.1.1 Each machine is fitted with a power cable based on the input voltage connected
to the appropriate selection. Do not select the wrong voltage.
6.1.2 With the corresponding input power supply terminal or socket, ensure good
contact and prevent oxidation.
6.1.3 A multi meter measures the input voltage is within the fluctuation range.
6.1.4 Clamp the front panel connector into the jack at the bottom of the cathode and
tighten clockwise.
6.1.5 Clamp the cable plug into the front panel below the negative welding socket and
tighten clockwise.
6.1.6 Ensure a good earth.
See above (4) and (5) for DC reverse operation.
Select DCSP operation when using base metals and welding rods.
In general, the basic electrode reverse method is recommended (ie, connected to a
positive electrode). When using acid electrodes take extra care.
6.2 Operation
6.2.1 Use the above method for correct installation. Turn the power switch to ‘ON’
and the power indicator light and fan come on – the device is working correctly.
6.2.2 Note the polarity of wiring. Generally DC welding wires are connected in two
ways – positive and reverse polarity.
Positive Connection: Welding clamp then negative, then positive, then positive
work piece; reverse law contrary. Select according to technical requirements.
An incorrect selection can result in arc instability and spatter etc.
6.2.3 If the work piece distance from the welding machine to the second line
(electrode holder and ground) is longer, choose the appropriate conductor.
A cross-sectional area should be larger to reduce cable voltage drop.
6.2.4 According to the standard pre-set welding electrode current, the electrode clip
will be sufficient and you can use short-circuit arc welding. For welding
parameters refer to 6.3.
