3.1.1 Place the welding machine on a solid and stable platform.
3.1.2 If necessary, u se a 250VD.C.isolation meter to check the isolation between
the input power lines and the chassis. The resistance should be greater
than 2 MO .( due to t he internal electronics, the control circuit wiring
should be disconnected for proper measurement of isolation)
.
3.1.3 Connect the input power plug to a suitable and safe power socket. Proper
grounding is mamdatory.
3.1.4 For pneumatic welding gun systems:
(1)Connect the pedal/push button switch to the connector on the front of
the control unit;
(2)Clean the air hoses and assembly, and then connect the air outlet from
the air-compressor to the air inlet on the right hand side of the
welding machine;
3.1.5 Output Power Selection:(to be set according to customer requirements)
There are three selections of output power ranges, as shown in Figure 1.
The selections can be made with the position of the copper bars at the
back of the control unit:
