Adjustment of wire brake
The wire brake must ensure that the wire reel brakes
sufficiently before the welding wire runs over the
edge of the reel.
The brake force is dependent on the weight of the
wire reel and wire feed speed.
Factory setting is 15kg.
Adjustment:
• Dismount the
control knob by
placing a thin
screw driver behind
the knob and
thereafter pull it
out.
• Adjust the wire
brake by fastening
or loosening the self-locking nut on the axle of
the wire hub.
• Remount the control knob.
Connection of shielding gas
The shielding gas hose is fitted to the back panel
of the power source (3) and is connected to a gas
supply with a pressure reduction to 2-6 bar. One gas
cylinder can be mounted on the bottle carrier on the
back of a trolley if any.
Torch adjustment (Dialog torch)
The current size/wire feed speed can be adjusted
both from the machine and the welding torch if a
welding hose with dialog torch is in use. The torch
adjustment is passive without Dialog torch.
Inching
The function is used for wire
inching e.g. after change of
wire.
Gouging (only OMEGA
2
550)
1. Mount the carbon-arc torch
2. Mount the compressed air hose on the
compressor. Set the pressure between 5 and
7bar
3. Select MMA program. Set the machine at
max. current – not less than 400A
4. Select carbon electrode (6-8 mm)
5. Use protective equipment: ear protection,
welding goggles, gloves etc. Note! Metal sparks
pose fire danger.
