ERGOFRESH MIG WELDING TORCH
OPERATION
Check before welding
1. Check that the earth return cable is
connected to the welding equipment and
to the piece to be welded.
2. Check that the filler wire size is suitable
for the job.
3. To start welding, press the welding
switch on the welding torch handle.
Measuring fume extraction air flow
Before welding, measure the fume
extraction air flow with a fume extraction
air flow meter. Air flow should be measured
with torch in vertical position.
1. Insert the vacuum nozzle of the welding
gun into the fume extraction air flow
meter.
2. Turn the fume extraction on.
3. Check that the red O-ring is placed in
the green area (optimal fume extraction)
according to the torch model (see the
above image of the flow meter)
Fume extraction air flow
Fume extraction torches need to provide
the appropriate amount of shielding gas
to protect the weld from defects without
compromising the fume capture efficiency
of the torch. If the fume extraction air flow
is too strong, it captures shielding gas. If
the fume extraction air flow is too weak, it
doesn't capture welding fumes effectively
enough.
Decreasing fume extraction air flow
To decrease the fume extraction air flow,
use the air flow bypass valve on the torch
handle. The bypass valve should normally
be closed and opened only when extraction
disturbs the shielding gas flow, for example
when approaching the corner of the plates.

The welding arc radiation and spatters cause damage to eyes and unprotected skin.
Always wear welding helmet with eye protection, protective gloves, clothing and
footwear when welding.
Before using the torch, ensure that all the cables are in serviceable condition and
that the connectors are correctly fastened.
Do not bend cables and hoses in order to avoid damages that may prevent proper
gas and coolant circulation.
Important information on the safe use of the MIG welding torch. Rating of electrical
controls incorporated in the torch: 32VDC 0.05A.
Cooling unit power for water-cooled torches: Minimum 800W.
