When changing the input voltage connections, the
unused lead must be insulated and positioned to
prevent contact with any other internal components
of the machine or the machine side panel. The clear-
ance between the unused lead and other compo-
nents must be at least one inch (see Fig. 3.3B for
illustration of the proper position). FAILURE TO
INSULATE AND POSITION THIS LEAD PROPERLY
WILL CAUSE A SERIOUS SHOCK HAZARD.

The terminal labeled GRD is connected to the welding
machine chassis and is for ground purposes only. It
must be connected to a good electrical ground. Do
not connect a conductor from the terminal labeled
GRD to any one of the L1, L2 terminals as this will
result in an electrically hot welding machine chassis.
3.2.3 Connecting FOR 208 VAC INPUT
After the panel is removed, locate the 208 Vac lead (Fig.
3.3B) and cut the tie-wrap to remove the insulation
sleeving (on early models this lead may have been
wrapped with black electrical tape). Open the insulating
cover around the power switch (Fig. 3.3C.) to expose the
terminals and disconnect the 230 Vac lead from the top
of the switch as shown in Fig. 3.3A. Insulate the 230 Vac
lead that was removed from the power switch with
sleeving or approved electrical tape and re-position to a
safe area beside the transformer (see Fig. 3.3B), leaving
a minimum of one inch clearance from other compo-
nents and the side panel.
3.2.4 CONNECTING FOR 230 VAC INPUT
After the panel is removed, locate the 230 Vac lead (Fig.
3.3B) and cut the tie-wrap to remove the insulation
sleeving (on early models this lead may have been
wrapped with black electrical tape). Open the insulating
cover around the power switch (Fig. 3.3C.) to expose the
