1. To set up optional Spool Gun (sold separately), plug Ground Clamp Cable into
Negative (–) Socket. Plug polarity switch cable into Positive (+) Socket. Twist
cables clockwise all the way to lock in place.
2. Loosen the Knob on the Wire Feed mechanism, then insert the Spool Gun Cable
Connector through the hole on the Welder front and into the socket on the Wire Feed.
3. Ensure Cable Connector is fully inserted and tighten the Knob securely.
If Connector is not fully inserted, the gas connection will leak, preventing
shielding gas from reaching the welding arc.
NOTICE: To prevent damage, do not overtighten the Knob.
4. Insert the Wire Feed Control Cable into hole on Welder front , then tighten lock
ring on the Cable plug. Note that the plug on the Cable fits into the Socket in
one specific orientation only.
5. Connect Gas Hose on Spool Gun Cable Connector to Spool Gun Gas Outlet on
front of Welder.
6. Refer to Spool Gun manual for operational information.
BASIC WIRE WELDING
Read the ENTIRE IMPORTANT SAFETY INFORMATION section at
the beginning of this manual including all text under subheadings therein
before welding.
WARNING
TO PREVENT SERIOUS INJURY:
Protective gear must be worn when using the Welder; minimum shade number 10
full face shield (or welding mask), ear protection, welding gloves, sleeves and apron,
NIOSH-approved respirator, and fire-resistant work clothes without pockets should
be worn when welding. Light from the arc can cause permanent damage to the eyes
and skin. Do not breathe arc fumes.
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 dierent thickness of material
• a dierent type of material
• a dierent type of connection
• using a dierent process
