SPOT WELDING
This type of welding is used for spot welding two overlap-
ping,sheets, and requires the use of a special gas nozzle.
Fit the spot welding gas nozzle, press it against the piece to be
welded, then set the TIMER (Ref. 2 - Picture 1 Page 3.) to 1/3 of
the timer scale.
Press the torch button; note that the welder will eventually detach
from the piece. This time period is fixed by the TIMER control, and
must be set depending on the thichness of the material.

MAINTENANCE
DISCONNECT THE POWER SOURCE FROM POWER MAINS
BEFORE PERFORMING ANY MAINTENANCE WORK.
Periodically (i.e. every 5-6 months) remove accumulated dust
from the inside of the welding unit with a jet of dry compressed air
(after removing side panels).
BE EXTREMELY CAREFUL TO AVOID BENDING MOVE-
MENTS, WHICH COULD DAMAGE AND CHOKE THE TORCH.
PERIODICALLY CHECK the condition of the torch, which is
the part most subject to wear.
Avoid sudden bending movements of the cable. Never move the
welder by pulling the torch.

CONNECTING THE TORCH
Prior to connecting the torch, make sure that the wire sheath is
suited to the diameter of the wire used.
Check that the groove on the wire feed roller and the wire guide
tube correspond to the diameter of the wire to be used, and that
the guide tube does not come into contact with the roller.
