4.1.
LEAD CONNECTION
MMA Mode: Connect the electrode holder to the Positive (+) connector (fig.1.4) and the earth lead to the Negative (-) connector (fig.1.3).
TIG Mode: Connect the earth clamp to the Positive (+) connector and the TIG torch to the negative (-) connector.
4.2.
GAS CONNECTION
4.2.1.
Using the clear tubing supplied connect the regulator to the gas inlet on the back of the inverter and gas outlet on the front (fig.1.1).
Secure the tubing on each connector by using the worm drive clamps supplied.
4.2.2.
Open the regulator before opening the cylinder valve. Test for leaks.
4.2.3.
Set the gas flow to suit the welding parameters required.
4.2.4.
If necessary the gas flow can be adjusted during welding using the regulator knob.
4.3.
If using the optional torch kit, connect the control lead of the torch assembly to the torch control connection (fig.1.2).
4.4.
MMA: DC STICK ARC WELDING
4.4.1.
Using the Up and Down keys, set the welding mode selector (fig.2.1) to
adjustment knob (fig.2.5).
4.4.2.
The hot start current (fig.3.B) and arc force current only (fig.3.K) can be adjusted in this mode to match the material being welded.
4.4.3.
To select the parameter push the parameter setting control to cycle between functions. The value may be adjusted by using the
adjustment knob (fig.2.1).The values are displayed on the digital display. (fig.2.4)
4.5.
DC TIG WELDING
4.5.1.
Using the Up and Down keys, set the welding mode selector (fig.2.1) to
4.5.2.
The pre-flow time (fig.2.A), welding current (fig.2.D) and gas delay time indicator (fig.2.J) may be adjusted in this mode.
4.5.3.
To select the parameter press the parameter setting control to cycle between functions. The value may be adjusted rotating the
setting control (fig.2.5).
4.5.4.
2 or 4 touch trigger control may be selected by using the trigger mode selector (fig.2.3).
4.5.5.
2 touch allows the power to be applied whilst the trigger is pressed.
4.5.6.
4 touch latches the trigger until the pressed for a second time.
4.5.7.
The 4 touch mode is useful for long runs of weld, saving operator fatigue and allowing a steadier weld. In this mode the power will be
applied until the selected down slope time has elapsed.
4.6.
DC PULSE TIG WELDING
4.6.1.
Using the Up and Down keys, set the welding mode selector (fig.2.91 to
4.6.2.
Select the pulse function at fig.2.2.
4.6.3.
The pre-flow time (fig.2.A), pulse peak current (fig.2.D), pulse width (fig.2.F), pulse frequency (fig.2.G), pulse background current
(fig.2.G) and gas delay time (fig.2.J) may all be adjusted in this mode.
4.6.4.
To select the parameter press the parameter setting control to cycle between functions. The value may be adjusted by rotating the
setting control (fig.2.5).
4.7.
STATUS WARNING LIGHTS
4.7.1.
Power Indicator (fig.2.6). Indicator illuminated when switched on.
4.7.2.
Overheat Indicator (fig.1.7). Illuminated when machine is overheated. In this condition the machine will shut down until the temperature
falls to acceptable limits.
4.7.3.
Over/under voltage. Indicates that the supply voltage is outside the required parameters.
5. MAINTENANCE
DANGER Unplug the inverter from the mains power supply before connecting or disconnecting cables, performing maintenance or
▲
service. Direct contact with the inverter circuit is dangerous.
5.1.
To avoid a build up of dust inside the machine which may block or restrict the ventilation system, periodically remove the covers and
remove the dust with a low pressure air jet or vacuum cleaner. Replace covers immediately. Under no circumstances should the
machine be operated with the covers removed.
5.2.
TORCH. Avoid resting the the torch and its associated cable on any hot surfaces. If the insulation is damaged in any way the torch
must not be used.
5.3.
Periodically check the condition of the gas tubing and the connections.
6. RATINGS PLATE SYMBOLS
