OPERATION 4-6 0-5492
15. Arc Control (Inductance)
The arc control operates in MIG(GMAW) mode only and is used to adjust the intensity of the welding arc.
Lower arc control settings make the arc softer with less weld spatter. Higher arc control settings give a stronger
driving arc which can increase weld penetration.
16. Gas Inlet (MIG mode only)
The Gas Inlet connection is a quick connect type inlet fitting used to supply the appropriate MIG welding gas
to the unit. Refer to section 5.09 for MIG set up details.
!
WARNING
Only Inert Shielding Gases specically designed for welding applications should be used.
17. Fan
The Fan is turned ON/OFF by the Power Switch on the rear panel of the machine.
18. On/Off Switch
This switch is used to turn the unit ON/OFF. When this switch is turned ON the Power Indicator on the front
panel will illuminate.
NOTE
If the Power Source is repeatedly switched On then O rapidly or the supply to the power source is turned On and O
rapidly it may not turn On due to inbuilt protective devices acting. If this occurs leave the Power Source On/O switch
turned to the O position for several minutes to allow for the protective devices to reset.
19. Local / Remote Switch (located in wirefeed compartment of WeldSkill 185 only)
The Local / Remote switch is used only when the unit is in Lift Tig Mode and a Tig Torch with Remote Current
Control or the unit is in Mig Mode and a Spool Gun is fitted to the unit via the 8 Pin remote control socket (item
12) located on the front panel. When the Local/Remote switch is in the Remote position, the unit will detect the
remote device and work accordingly. When in the Local Mode, the unit will not detect the remote device and
will operate from the power source controls only. Note that the trigger will operate at all times on the remote
control socket irrespective of the position of the Local / Remote switch (ie in both local and remote modes).
When the Local/Remote switch is set to Remote mode, if the unit is in Lift Tig mode and a Tig Torch with
Remote Current Control is connected the current output value will be controlled only by the Tig Torch Remote
Control. If the unit is in Mig Mode and a Spool Gun fitted with wirespeed control is connected the Spool Gun
wirefeed speed will be controlled by the Spool Gun Control. The power source control will be disabled.
20. Burnback Control (located in wirefeed compartment)
The burnback control is used to adjust the amount of MIG wire that protrudes from the MIG torch after the
completion of MIG welding (commonly referred to as stick out). To decrease the burnback time (or lengthen
the amount of wire protruding from the MIG torch at the completing of welding), turn the burnback control
knob anti clockwise. To increase the burnback time (or shorten the amount of wire protruding from the torch
at the completing of welding), turn the Burnback Control knob clockwise.
21. Hot Start Feature (Not Shown)
This feature operates in Stick (MMAW) mode. The Hot Start feature improves the arc start characteristics by
momentarily increasing the welding current to a level above the preset amperage (Welding Current). This is a
preset feature and is not adjustable.
22. Anti Stick Feature (Not Shown)
This feature operates in Stick (MMAW) mode.
The anti stick feature senses when the electrode sticks and automatically reduces the current to prevent the
Stick Electrode from sticking to the work piece. This is a preset feature and is not adjustable.
