Note. The welding machine is equipped with a
remote receptacle and can be operated by remote con-
trol. When using the remote control, the contactor
and amperage switches must be in the remote position.
When the remote amperage control is used, the maxi-
mum current available will be limited by the sitting
of the panel rheostat. If full range is necessary, the
panel rheostat control must be set wide open.
2-14. Operation in Extreme Cold
(Below 0 F)
a. Frequently inspect for frozen water pipes
or lines.
b. If freezing is evident, disconnect the wa-
ter system from the welding machine and use
only for regular are welding.
2-15. Operation in Extreme Heat
a. Frequently inspect the fan motor and
lubricate as necessary in accordance with the
current lubrication order.
b. Make sure the welding machine has ade-
quate ventilation.
