Installation and operation
Note!
•
Only install the machine according to the steps below.
•
Switch off the power supply before performing the electric connections.
•
The IP code of the machine being IP21S, the machine must not be used in the rain.
Installation
1.
Connect the power cable to the power supply.
2.
Using a multimeter, check if the voltage value is comprised within an acceptable range.
3.
Plug the electrode holder into the “+” connection of the front of the welding machine and tighten
it clockwise.
4.
Plug the cable plug into the “–” connection of the front of the welding machine and tighten it
clockwise.
5.
For safety reasons, an earth connection is required.
The connection mentioned in step 4 and 5 is the DCEP connection (positive polarity). The user can
choose the DCEN connection (negative polarity) according to workpiece and electrode application Gen-
erally, the DCEP connection is recommended for basic electrode; for acid electrodes, there are no spe-
cial requirements.
Operation
1.
After installing the machine as described and switching the power switch on, the machine is
started with the power LED lit and the fan running.
2.
When connecting, ensure proper polarity. Phenomena such as instable arc, weld spatters, or
sticking of the electrodes might occur with the bad operation mode chosen. Reverse polarity if
necessary.
3.
With the MMA/WIG switch being switched to MMA operation mode position, normal welding is
possible with nominal output current. With the MMA/WIG switch being switched to WIG position
and drawn arc mode used, the arc can be ignited with the nominal current of the arc ignition.
Normal welding can be performed with the nominal welding current.
4.
Choose a cable with a bigger cross section to reduce potential drop if the secondary cables
(welding cable and earth cable) are long.
5.
Adjust the welding current according to the type and size of the electrode. Disconnect the elec-
trode, then weld with short-circuit arc. The welding parameters are found in the following section.
