FABRICATOR 210
INSTALLATION 3-4 Manual No. 0-4855
4. Fix the cable stowage hook to the Power Supply
cylinder bracket with the bolts provided.
5. Fit the gas Regulator/Flow Meter to the gas
cylinder and connect the gas hose from the rear
of the Power Supply to the Flow Meter outlet.
6. The machine is fitted with a .035/.045” vee groove
feed roll suited for hard wire. Change this feed
roll if required to fit your chosen wire size.
7. Fit the electrode wire spool to the wire reel hub
located behind the electrode wire compartment
door.
8. Fit the TWECO Weldskill MIG gun and trigger
wires through/to the front of the unit.
9. Remove the contact tip from the gun.
10. With the gun lead reasonably straight, feed the
wire through the wire drive rolls and gun.
11. Fit the appropriate contact tip and replace
insulator and nozzle.
3.07 Installation of Shielding Gas
(GMAW) Process
NOTE
Shielding Gas is not required if the unit is used
with self shielded FCAW (flux cored arc
welding) wires
1. Cylinder positioning: Block the wheels of the unit so
it cannot roll. Carefully stand the cylinder on the tray
and with one foot press against the bottom of the
cylinder to assure it is against the back of the unit.
Chain the cylinder in place. (Refer to Figure 3-2 for
Wheel Kit cylinder installation)
2. Cracking: Remove the large metal cap on top of the
cylinder by rotating counter clockwise. Next remove
the dust seal. Position yourself so the valve is pointed
away from you and quickly open and close the valve
for a burst of gas. This is called “Cracking” and is
done to blow out any foreign matter that may be
lodged in the fitting. (Figure 3-2.)
3. Fit Regulator/Flow Meter to cylinders: Screw the
regulator into the appropriate cylinder. (Figure 3-2)
The nuts on the regulator and hose connections are
right hand (RH) threaded and need to be turned in a
clockwise direction in order to tighten. Tighten with a
wrench.
CAUTION
Match regulator to cylinder. NEVER CONNECT
a regulator designed for a particular gas or
gases to a cylinder containing any other gas.
4. Attach supplied gas line between the regulator output
and the desired input at the rear of the power supply
depending on Spool Gun or MIG Gun use. (Refer to
Figure 3-2 and 3-13).
