4T (Latch mode)
This mode of welding is mainly used for long welding runs to reduce operator fatigue. In this
mode the operator can press and release the torch trigger and the output will remain active.
To deactivate the power source, the trigger switch must again be depressed and released,
thus eliminating the need for the operator to hold the torch trigger.
13. Process selection control
The process selection control is used to select the MIG (GMAW/FCAW) welding mode. See
the following sections: "Setup for MIG (GMAW) welding with gas shielded MIG wire" and
"Setup for MIG (FCAW) welding with flux core (gasless) wire".
14. Digital voltage meter (Left Side LED 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
multifunction control knob (10).
NOTE!
The preview functionality provided on this power source is intended to
act as a guide only. Some differences may be observed between
preview values and actual welding values due to factors including the
mode of welding, differences in consumables/gas mixtures, individual
welding techniques and the transfer mode of the welding arc (dip
versus spray transfer). Where exact settings are required (in the case
of procedural work), it is recommended that alternate measurement
methods be utilized to ensure output values are accurate.
15. Gas
inlet
The gas inlet connection,5/8-18 UNF female thread is used to supply the appropriate MIG
welding gas to the power source. See "Wire reel brake" and "Setup for MIG (GMAW) welding
with gas shielded MIG wire" section.
WARNING!
Only inert shielding gases specifically designed for welding
applications should be used.
16. ON / OFF switch
This single phase circuit breaker performs a dual function.
It is used to turn the unit ON/OFF and it will also trip in the event of a fault.
17. Manual switch
When the welding power source is empty, press the Manual switch to feed the wire.
18. Cooling fan
The fan and the power source work synchronously, when the power source is switched on,
the fan switches on too, but if there is no load the fan switches off, unless the unit is in
overtemp condition.
WARNING!
When the front digital displays are lit, the machine is connected to the
electricity supply and the internal electrical components are at mains
voltage potential.
