Setup for Solid Core (gas shielded) welding:
a. Connect the Wire Feed Connector to the
Positive Terminal on the front of the Welder.
Connect the Ground Cable to the
Negative Terminal on the front of the Welder.
b. Determine which type of shielding gas
would be appropriate for the welding
you will do. Refer to the Settings Chart
on the inside of the Welder door.
c. With assistance, set the cylinder (not included)
onto a cabinet or cart near the Welder
and secure the cylinder in place with two
straps (not included) to prevent tipping.
d. Remove the cylinder’s cap. Stand to the
side of the valve opening, then open the
valve briefly to blow dust and dirt from the
valve opening. Close the cylinder valve.
e. Locate the Regulator (included) and close its
valve until it is loose, then thread Regulator
onto cylinder and wrench tighten connection.
M)/25 When using C100 shielding gas, connect a CGA
580/320 adapter (not included) to the inlet connection
of the Regulator and wrench tighten. Thread the
adapter onto the gas cylinder and wrench tighten.
f. Attach the Gas Hose (included) to the
Regulator’s outlet and the Welder’s gas inlet.
Wrench-tighten both connections.
g. Connect the Wire Feed Gas Hose within
the Welder to the Gas Quick Connector.
The collar on the Gas Quick Connector must
click into place after attaching any hose to it.

20. Make sure the welding wire is resting in the groove
of the Feed Roller, then push the wire Idler Arm
down, and swing the Feed Tensioner up to latch it
across the tip of the arm.
After the wire is held by the Tensioner,
you may release it.
M)/25 The tension should be 3 – 5 for solid wire and
2 – 3 for flux-cored wire. Too much force on flux-cored
wire will crush it and may cause feeding issues.
21. Pull and twist the Nozzle to remove it.
22. Unscrew the Contact Tip
counterclockwise and remove.
23. Lay the MIG Gun Cable out in a straight line so
that the welding wire moves through it easily.
Leave the cover open, so that the feed
mechanism can be observed.

27. To check the wire’s drive tension, press and
hold Trigger to feed the wire against a piece of
wood from 2 to 3 inches away.
If the wire stops instead of bending,
unplug the Welder, slightly tighten the
Feed Tensioner clockwise, and try again.
If the wire bends from the feed pressure,
then the tension is set properly.
28. Turn OFF the Power Switch and unplug the

Flux-cored wire welding is used to weld mild steel
and stainless steel without shielding gas.
MIG welding uses solid wire and shielding gas,
and is used to weld mild steel and stainless steel.
MIG welding can also be used to weld thinner
workpieces than flux-cored welding can.
Aluminum welding can be performed with an
optional Spool Gun (sold separately) using
aluminum wire and shielding gas.
Good welding takes a degree of skill and experience.
Practice a few sample welds on scrap before
welding your first project. Additional practice
periods are recommended whenever you weld:
• a different thickness of material
• a different type of material
• a different type of connection
• using a different process (MIG vs. Flux)
