If the optional 25 foot Control Cable Extension is used, | Problems with the trigger interlock may be experienced | |||||||
it should be plugged into the | when using the MIG PULSER with an | |||||||

WELDING |
|
|
|
|
|
|
| |
Pulse welding generates high peak currents, which in |
|
| ||||||
| ||||||||
turn cause large voltage drops in welding cables. It is |
|
|
| |||||
essential that large cables (2/0 minimum) are used and |
|
|
| |||||
that all connections are clean and tight. |
| ! |
| |||||
|
|
|
|
|
|
| ||
Because of voltage drops, the total length of the weld- | $$ |
|
| |||||
%& |
|
| ||||||
|
|
| ||||||
ing leads (work lead length plus electrode lead length) |
|
|
| |||||
should not exceed 50 feet. If longer cables are used, |
| |||||||
|
| ! | ||||||
the maximum | achievable output | voltage will be |
|
| ||||
|
|
| ||||||
reduced. |
|
|
|
|
|

|
|
|
|
|
| |||
|
|
|
|
|
|
| ||
NOTE: Do not coil the output cables around any |
| |||||||
metal object. |
