CONTROL SWITCHES
1. Switch:
2-times
symbol
Start welding by pressing the trigger on the
torch. Welding continues until the trigger is
released.
Spot
symbol
The switch is set at Spot. When the trigger on
the torch is pressed, welding starts. Welding
stops automatically, depending on the time set
on control 4 (0.15-2.5 secs.)
Stitch
symbol
The switch is set at Stitch. When the trigger is
pressed, welding starts. The welding auto-
matically stops, depending on the time set on
control 4. After an interval fixed at control 5
the same cycle continues automatically and
only ceases when the trigger on the torch is
released.
4-times
symbol
Welding starts the first time the trigger is
pressed (after which the trigger can be re-
leased) and continues until the trigger is
pressed again to stop the welding process.
2. ON
Lights when the machine has been turned on.
3. Overheating
Lights if the welding process is automatically
stopped due to overheating of the transformer.
The light extinguishes when the transformer
temperature has dropped to normal, and weld-
ing can continue.
4. Welding time
With this control the welding time can be in-
finitely varied between 0.15 and 2.5 secs when
switch 1 is set to position Spot or Stitch.
5. Pause time
With this control the pause time can be infinitely
varied when switch 1 is in position Stitch.
6. Burn-Back
Variable time delay for wire to stop feeding
after voltage is switched off. This function is
used to prevent the wire sticking to the work-
piece or torch.
Variable between 0.05 and 0.5 secs.
7. Wire feed speed control
Infinitely variable (0.5 - 14 m/min).
8. Switch for welding voltage
For machines with "Gas-test".
When set at "Gas-test", the gas flows when the
torch trigger is pressed.
9. Main switch
10. Connection of welding hose
11. Earth cable
12. Plug
Mains voltage tap 230 V AC intended for elec-
tric hand tools.
13. Automatic fuse 10 A
For plug (pos. 12). The plug can be reclosed by
pushing the button.
NB!
Pos. 12-13 is special equipment for model 183-223-
273 in 400 V standard version.
