Commissioning
Before operating the device, ensure that you have read and familiarised yourself with the information
and security instructions found in this instruction manual. Further make sure to don adequate safety
gear, to use sufficient aeration equipment and to have removed all flammable materials from the work-
ing area and its vicinity.
1. Connect the earthing terminal to the workpiece you wish to wish to work on and ensure that a
proper electric connection is established.
2. Remove all traces of rust or paint from the spot you wish to weld.
3. Use the controls (Fig. A and B) to set the power output as well as the wire feed speed accord -
ing to the requirements of your task. When configuring the device, make sure to consider the
type of material you are working on, its thickness as well as the thickness of the wire you are
using.
4. Connect the power chord to the mains supply and turn the device on.
5. Cut excess wire hanging from the tip of the burner down to a length of 3 mm.
6. Position the tip of the burner about 6 mm away from the point that you want to start welding
from. The distance between the tip of the burner and the workpiece should thereby not exceed
10 mm in order to be able to achieve ideal welding results.
7. Cover your eyes with a welding shield by closing the visor of your welding helmet or holding a
welding shield in front of your face.
8. Pull the trigger in order to create an arc. The creation of an arc means that the device started
conveying wire.
9. If the weld nugget is large enough, slowly move the burner along the path you wish to weld.
10. The burner emitting an unusually loud buzzing noise and a tear forming at its tip indicate that
the wire feed speed setting is too low and should be increased. Irregular sounds and spatter
on the other hand indicate that the wire feed speed setting is too high. When operating with an
ideal wire feed speed, a steady noise should be heard. A porous welding seam indicates a
lack of gas supply.
11. Please check the name plate for information concerning the duty cycle of the device. The val -
ues stated in % describe the period of use within a cycle of 10 min. 60 % for example indic-
ates a period of use of 6 min and a rest period of 4 min. In case of the welder being over-
loaded, the device will automatically stop operating in order to prevent its components from
being damaged. In case of an automatic shutdown, give the device a sufficient amount of time
to cool down. Leaving it turned on during the cooling period will allow the internal fan to speed
the process up.
