5.3 Welding Preparation
Read the safety instructions in chapters 1, 3 and 5.
Observe the workplace requirements (chapter 3, ”Starting-up").
Check all cables and connections for proper condition.
Replace immediately defective cables and cable connections to avoid electrical
shocks.
Check the chuck for proper seat (see operating manual of according welding
gun).
Before welding, make sure that the bellows are checked for damage and proper
seat.
5.4 High-strength Welds
The following must be removed both from the weld zone and the ground clamp
connection areas:
– paint, oil and any other impurities,
– rust,
– non-conductive coatings from surface treated work pieces.
Weld to smooth and flat surfaces only.
For welding to pipes or punched plates consult our responsible
application manager (address of customer service see page ii).
5.5 Determination of Welding Parameters
The adjustment of welding parameters on the power unit (e.g. charging voltage via energy
controller) or on the welding gun (e.g. spring force) depends amongst others on
– material of the welding element
– diameter of the welding element
– material of the work piece
The guidelines should be verified by test welding on the actual material and be changed
if necessary. For an assessment of welding results, see section 5.8 and 5.9.
