OTHER RECOMMENDATIONS
1.
The shortest weld time, consistent with doing a satisfactory weld, is the best as heat in both the hand
attachment and cables is kept to a minimum .
2.
Better results will be obtained by moving the ground clip closer to the weld, than by increasing either the
weld time or the weld power .
3.
Keep the electrode tip diameter to the absolute minimum .
4.
Maximum gauge that can be welded is 2 x .75mm . In all cases, the maximum thickness can be welded,
either to itself, or to anything thicker .
Generally speaking, short weld times and high power settings will give the best results .

RESISTANCE WELDING
WHAT IS AC RESISTANCE WELDING?
Alternating Current (AC) welding uses electric voltage directly from an alternating current outlet . AC flows half
the time in one direction and half the time in the other, changing its polarity 120 times per second . AC welders
have advantages over other welder types:
