OPERATION - MMA
Before starng any welding acvity ensure that you have suitable eye protecon and
protecve clothing. Also take the necessary steps to protect any persons within the welding
area.
MMA operaon steps
MMA welding current
Select the welding current seng funcon by pressing
the MMA welding parameter selecng key and welding
current in MMA can be set. The current parameter range
is 20~210 amps and is adjusted via the adjustment knob
and the pre-set amperage is indicated on the front panel
digital display.
The Welding current seng can be carried out during welding.
MMA hot start
Select the hot start seng funcon by pressing the
welding parameter selecon key unl the hot start LED
Illuminates. The hot start parameter range is 0~60amps
and is adjusted via the adjustment knob and the
and the hot start addional amperage is indicated on the
front panel digital display.
The Hot start amperage seng can be carried out during welding.
MMA arc force
Select the arc force seng funcon by pressing the
welding parameter selecon key unl the arc force LED
Illuminates. The arc force parameter range is 0~60amps
and is adjusted via the adjustment knob and the
and the arc force addional amperage is indicated on the
front panel digital display.
The arc force amperage seng can be carried out during welding.
If the secondary cables (welding cable and earth cable) are long, select cable with larger cross-secon to
reduce the voltage drop.
Please ensure to check that you have the electrode polarity correct to your chosen electrode and that you
set the pre-set output amperage correctly for the electrode being used.
MMA welding electrodes vary
depending on material, work piece
thickness, welding posion and
joint form.
Pre-set the welding current
according to the type and size of
the electrode, clip the electrode
and then welding can be carried
out by short circuit arc ignion.
For welding parameters, please
refer to the opposite table.
