ASSEMBLY & INSTALLATION
Letter references in parenthesis (A) refer to the included Identification Key. Dashed numbers in
parenthesis (Fig. 1-1) refer to specific point of an illustration or image
1.
Connecting the cables:
1.1 Connect the ground cable (K) into the negative outlet socket (D) when using gas or a
shielded wire.
1.2 Connect the ground cable (K) to the positive outlet socket (C)
for gasless wire.
2.
Connect the power cable (F) to the opposite outlet socket.
3.
Fit the gas line onto the gas inlet (J) barb. Secure with a hose clamp if
necessary.
4.
Connect the gas regulator (Fig. 2) to the gas cylinder or compressor.
5.
Connect the other end of the gas line to the regulator's barbed gas outlet.
6.
Install the welding wire if needed (See Wire Installation and Setup).
7.
Open the valve on the gas cylinder and set the flow to 0.35 CFM (8-10 L/min).
CHECK FOR GAS LEAKAGE
Check for gas leakage after each time the welding unit is set up and at regular intervals.
The recommended procedure is as follows:
1.
Connect the regulator and gas hose assembly, then tighten all connectors and clamps.
2.
Slowly open the cylinder valve.
3.
Set the flow rate on the regulator to approximately 0.35 CFM (8 to 10 L/min).
4. Close the cylinder valve and pay attention to the needle indicator on the regulator's
pressure gauge. If the needle drops away towards zero there is a gas leak.
Sometimes a gas leak can be slow and to identify. Leave the gas pressure in the regulator
and line for an extended time period. Perform the test as above. Close the cylinder valve
and check after a minimum of 15 minutes.
5.
After confirming there is a loss of gas, check all connectors and clamps for leakage by
brushing or spraying with soapy water. Bubbles will appear at the leakage point.
6.
Tighten clamps or fittings to eliminate gas leakage. Replace the clamps and fittings if this
fails to solve the problem.
WIRE INSTALLATION AND SET UP
The correct installation of the wire spool and the wire into the wire feed unit is critical to
achieving an even and consistent wire feed. Poor set up of the wire into the wire feeder is a
major cause of fault with MIG welding machines. The guide below will assist in the correct setup
of your wire feeder.
1.
Open the welding unit's top cover (Fig. 3).
2.
Remove the spool retaining nut (Fig. 4). The spool
retaining nut is left-hand threaded.
3.
Note the tension spring adjuster and spool locating pin
(Fig. 5).
4. Fit the wire spool onto the spool holder. Fit the locating
pin into the location hole on the spool. Reinstall the spool
retaining nut tightly (Fig. 6).
