OPERATION 4-4 0-5492
9. Digital Voltage Meter (Right Digital Display)
MIG Mode
This digital meter is used to display the pre-set (preview) Voltage in MIG mode and actual welding
voltage of the power source when welding. At times of non-welding, the digital meter will display a pre-
set (preview) value of Voltage. This value can be adjusted by varying the Voltage Control Knob (7).
STICK and LIFT TIG Modes
This digital meter is used to display the Welding Output Terminal Voltage in STICK / LIFT TIG modes
during non-welding or welding. This value Cannot be adjusted by varying the Voltage Control Knob (7).
When welding, this digital meter will display actual welding voltage in all modes.
At the completion of welding, the digital meter will hold the last recorded voltage value for a period
of approximately 10 seconds in all modes. The voltage meter will hold the value until; (1) any of the
front panel controls are adjusted in which case the unit will revert to preview mode, (2) welding is
recommenced, in which case actual welding amperage will be displayed, or (3) a period of 10 seconds
elapses following the completion of welding in which case the unit will return to preview mode.
NOTE
The preview functionality provided on this power source is intended to act as a guide only. Some dierences may be
observed between preview values and actual welding values due to factors including the mode of welding, dierences
in consumables/gas mixtures, individual welding techniques and the transfer mode of the welding arc (ie dip versus
spray transfer). Where exact settings are required (in the case of procedural work), it is recommended that alternate
measurement methods be utilised to ensure output values are accurate.
10. MIG Torch Adaptor (Euro Style)
The MIG torch adaptor is the connection point for the MIG welding torch. Connect the torch by pushing the
torch connector into the brass torch adaptor firmly and screwing the plastic torch nut clockwise to secure in
position. To remove the MIG torch simply reverse these directions.
11. MIG Torch Polarity Lead
The polarity lead is used to connect the MIG torch to the appropriate positive or negative output terminal
(allowing polarity reversal for different welding applications). In general, the polarity lead should be connected
in to the positive welding terminal (+) when using steel, stainless steel or aluminium electrode wire. When
using gasless wire, the polarity lead is generally connected to the negative welding terminal (-). If in doubt,
consult the manufacturer of the electrode wire for the correct polarity. It is essential, however, that the male
plug is inserted and turned securely to achieve a sound electrical connection.
CAUTION
Loose welding terminal connections can cause overheating and result in the male plug being fused in the Dinse terminal.
