Assembly (Continued)
Obtaining Correct Gas Type. The gas used in any welding
application for your welder must be an INERT, NON-
FLAMMABLE TYPE. You can get the type of gas needed from a
nearby welding gas distributor (often found in the yellow pages
under "Welders" or "Welding Equipment").
regulator
An adjustable regulator with two gauges is supplied with the
WG3090 and WG4130. The WG3080 is not supplied with a
regulator (see parts list for optional regulator/hose kit). The
regulator provides a constant shielding gas pressure and flow
rate during the welding process. Each regulator is designed to
be used with a specific gas or mixture of gases. The argon and
argon mixture use the same thread type. The 100% carbon
dioxide uses a different thread type. An adapter is available at
your local welding gas supplier to change between the two.
Hose and regulator HooKup proCedure
Cylinder gas is under high pressure. Point
cylinder outlet away from yourself and any
bystanders before opening.
1. With cylinder securely supported, stand on side of cylinder
opposite cylinder outlet then remove cylinder cap and open
valve slightly by turning counterclockwise. When gas is
emitted from cylinder, close valve by turning clockwise. This
will blow out dust or dirt that may have accumulated around
valve seat.
2. Install regulator onto cylinder valve. Tighten stem nut
securely to gas valve.
3. Install one end of gas hose to fitting on the back of welder
and other end of hose to fitting on regulator. Make sure gas
hose is not kinked or twisted.
4. While standing opposite cylinder outlet, slowly open cylinder
valve. Inspect for leaks in the connections.
5. Turn unit on and pull trigger on torch to allow gas to flow.
Adjust gas regulator to between 20 and 40 CFH. Release
trigger and turn unit off.
6. Remember to close gas cylinder valve when finished
welding.
Models: WG3080, WG3090 and WG4130
Operation
1. Be sure to read, understand and comply with all
precautions in the General Safety Information
section. Be sure to read entire "Welding
Guidelines" section before using this equipment.
2. Turn welder off.
3. Verify surfaces of metals to be joined are free from dirt, rust,
paint, oil, scale or other contaminants. These contaminants
make welding difficult and cause poor welds.
wear protective welding gear including: eye protection with
proper shade, flame resistant clothing, leather welding gloves
and full foot protection.
lead, or cadmium plated materials, refer to the
General Safety Information Section for instructions.
Extremely toxic fumes are created when these
metals are heated.
4. Connect work clamp to work piece or workbench (if metal).
Make sure contact is secure. Avoid surfaces with paint,
varnish, corrosion or non-metallic materials.
5. Rotate Wire Speed Control to setting per decal inside wire
feed compartment, then adjust as needed after test.
6. Plug power cord into a proper voltage receptacle with proper
circuit capacity (see circuit requirements on Page 1).
7. Switch welder on to desired heat setting per decal inside
wire feed compartment, then adjust as needed after test.
NOTE: These settings are general guidelines only. Heat setting
may vary according to welding conditions and materials.
8. Verify wire is extended 1/4 in. from contact tip. If not,
squeeze trigger to feed additional wire, release trigger, turn
welder off, and cut wire to proper length. Then, switch back
on to desired heat setting.
NOTE: The welder transformer is off and will not energize until
the trigger is pulled. This is a "cold torch" welding machine and
it will not weld until the trigger is pulled.
9. Position torch near work piece, lower welding helmet by
nodding head or positioning the hand shield, and squeeze
torch trigger. Adjust heat setting and wire speed as needed.
10. When finished welding, turn welder off and store properly.
