Main Unit Knob/Button/Function:
1. On/Off Breaker or Switch: Either breaker or switch located on the back or front of the
unit will control the unit to be turned on or off.
2 Power Indicator: Shows unit is powered on. Indicator is present in some models with a
green LED bulb.
3 Warning indicator: Illuminates when the duty cycle has been exceeded or the machine
has overheated due to improper ventilation. Discontinue use until lamp goes out. Allow
the fan to continue to run. Once lamp goes out, you may resume using the unit.
4 + / – Connections: Polarity and ground selection lugs. Correct use of polarity is the key
to weld quality. Follow the electrode and wire manufacturers recommendations for
polarity. For Stick or MIG mode, ground connection will be inserted into the negative
post for straight polarity.
5 Digital Voltage Meter: Indicates voltage setting while operating machine in MIG mode.
6 Current Meter: Indicates current setting while operating machine in Stick mode.
7 MIG/Stick Selector Switch: Toggle switch for MIG or Stick setting.
8 Spool Gun Connection: LONGEVITY offers an optional 8 meter speed adjustable spool
gun for the MIG welder function of this machine. This option will allow you to weld
aluminum and stainless steel. Please contact LONGEVITY welding for more details on
this optional accessory.
9 Welding Voltage Adjustment Knob: Turning this adjustment knob clockwise increases
the welding voltage in MIG mode.
10 Arc Force Adjustment Knob: This adjustment will allow you to adjust the ARC quality
of a weld in Stick or MIG mode. Using this function while MIG welding will allow you
to control the burn back and stick out. Using this function while Stick welding will allow
you to adjust the sharpness of your ARC. Setting experimentation may be required to find
a perfect setting for an individual welder.
11 Wire Speed/ Welding Current Adjustment Knob: This adjustment has a different
function for either mode used. This will control the wire speed adjustment for rate of wire
output while MIG welding. This adjustment will also control the amperage output for
Stick welding.
12 Fuse: Fuse may need to be replaced if there is no indication on the front panel display or
if the wire speed/welding current adjustment is not working. Must replace with an
applicable fuse for use with this machine. (Contact LONGEVITY dealer for
specifications.)
13 External Ground Lug: This may be used in some circumstances where extra grounding
is necessary for local electrical code compliance. This will allow you to ground the
machine separately with a separate wire connection. (Note: machine is grounded through
power cord.)
14 Gas Inlet: This will be the inlet of your shielding gas flow to the internal solenoid of the
machine. Use gas hose provided for this connection to the machine from gas bottle. Use
proper hose clamps for sealing hose to inlet.
