Operation
Before starting any welding activity ensure that you have
suitable eye protection and protective clothing. Also take
the necessary steps to protect any persons within the
area.
MMA
After connecting the welding leads as detailed you will need
to switch the power switch on the back panel to “ON”
Select MMA by switching to the MMA welding mode. There
is voltage output at both output terminals.
Set the amperage on the machine suitable for the electrode
being used. Please see below a guide to amperages
required. Ensure you check that you have the electrode
polarity correct.
TIG mode
Connect the TIG torch leads as detailed above. Ensure that a
suitable inert gas supply is connected.
Switch the power switch on the back panel to “ON”
Select the TIG welding mode using the selector switch.
There is voltage output at both output terminals.
After the parameters are set appropriately, open the gas
valve of the cylinder, the gas valve on the torch and adjust
the gas regulator to obtain the desired flow rate.
The arc will start when the tungsten electrode touches the
work piece and is lifted o
ff
after touching by between 2-4mm
The arc will cease when the electrode (torch) is moved away
from the work area
Select the spot welding time setting function by pressing
the welding parameter selecting key, and set the spot
welding time. Operation steps in spot welding:
Press the torch trigger, gas valve opens, and HF arc ignition
starts; Keep the torch 2~4mm away from the work piece to
TIG guides
The recommended size of tungsten to be used can be
selected from the table below
