ExERCISE ExTREME CAUTION - RISK OF FIRE AND/OR ELECTRIC SHOCK!
The following steps require applying power to the welder. Do not touch
anything with the Torch Handle or welding wire or an arc will be ignited. Do
not touch the internal components of the unit with it plugged in.
12. Plug the Power Cord into its electrical outlet and turn the welder ON.
13. Point the Torch Handle away from all objects and continue pressing the Trigger until
the wire feeds through two inches. Move the handle slightly in a circular motion to help
the wire feed properly out the end. If the wire does not feed properly and the reel is
stationary, turn the welder OFF, unplug it, slightly tighten the Wire Tension Adjusting
Screw (37), and rewind the wire slightly before retrying.
14. To check the wire’s drive tension, feed the wire against a piece of wood from 2 to 3
inches away. If the wire stops instead of bending, turn the welder OFF, unplug it, and
slightly tighten the Wire Tension Adjusting Screw (37).
9. Turn the Nozzle (3) counterclockwise while pulling to
remove.
10. Using the third oval hole on the provided Wrench (43),
turn the Contact Tip (2b) counterclockwise and remove.
11. Lay the Torch Cable out in a straight line so that the wire
moves through it easily. Leave the cover open, so that
the feed mechanism can be observed.
