METHOD OF OPERATION
EXAMPLE PROJECT SETUP #1
1.
Plug in welder and ensure the ‘Power On’ LED is illuminated .
2.
To use the PG2 hand attachment, push the copper jack plug into the left of the two sockets on the right
side of the welder, and the switch jack plug into the corresponding socket . Push the copper jack plug
on the ground clip into the other socket .
3.
When using the PG2 hand attachment, set the ‘Single/Repeat’ toggle switch to ‘Single’ .
4.
For sheet of .1mm, set ‘Rest’ time at 5 cycles, ‘Weld’ time at 4 cycles and ‘Power’ at 50% .
5.
Attach ground clip to the work piece as near to the weld location as possible to provide a good path for
the current during the weld time .
6.
Ensure that the welding electrode tip is dressed to a fine, slightly rounded point . Set the ‘On/Off’ switch
to ‘On’ . Place the electrode firmly onto the work piece and depress the micro-switch in the pistol grip .
7.
To use the roll spot wheel, unscrew the PG2 electrode, and replace it with the brass wheel holder . Set
the ‘Single/Repeat’ switch to ‘Repeat’ .
8.
Set the ‘Rest’ time to 5 cycles and the ‘Weld’ time to 2 cycles . The weld pitch can be adjusted as
required by changing the ‘Rest’ time .
9.
Holding the hand attachment in the air, initiate the weld, and adjust weld interval as required by looking
at the ‘Weld Go’ LED flashing and adjusting the ‘Rest’ time .
10.
Ensure that the grounding clamp is attached to the work piece as close to the weld as possible .
11.
Place the wheel on the sheet, press firmly, depress the micro-switch and keep depressed . Start to
move the wheel along as soon as the switch is depressed and maintain pressure until after the switch is
released or holes will be burnt in the sheet .
12.
To use the PG5 or PG5M hand attachments, push the copper jack plugs into the two sockets on the
right of the welder, and the switch jack plug into its socket .
13.
Set the ‘Single/Repeat’ switch to ‘Single’ and set the ‘Weld’ to 4 and ‘Power’ to 50% . To operate, place
the sheet or wire to be welded between the electrodes and squeeze the pressure lever into the grip .
The weld will initiate and stop after the time set on ‘Weld’ . Pressure must be fully released before
further welds can be made .
14.
Pressure and point of initiation can be adjusted by the screw above the moving electrode .
15.
With all Hand attachments increase power gradually until a test weld on a sample is stronger than the
parent metal and a ‘slug’ can be pulled .
16.
Generally as the thickness or the sheet or wire varies, increase or decrease the power to suit . Always
weld with the lowest Power setting and the shortest weld time commensurate with a good weld .
