penetration. However, in certain conditions, if the work piece be-
comes magnetized, or some part of the welding table does, then the
arc may become highly unstable while welding in DCEP. High
amounts of spatter and a wild, uncontrollable arc may be experi-
enced. This usually will occur while welding in corners. In this case,
this is referred to as
“
Arc Blow
”.
When Arc Blow happens, AC will
usually straighten up the arc, and force it where it needs to go. Keep
in mind that this is a very rare occurrence. And when AC isn
’
t availa-
ble, or practical, Arc Blow in DCEP can be combatted by changing the
location of the work clamp, or by wrapping the work clamp cable,
several times around the welding table leg, or item being welded.
The illustration below depicts the standard connection for most weld-
ing rods. Always consult your welding rod manufacturer
’
s recommen-
dation as an ultimate source of information. Usually the box or can
will have polarity recommendations along with Amp range recom-
mendations on it if you are in doubt about settings or polarity.
This welder is designed to weld with a variety of welding rods, includ-
ing E6011, E7014, E6013, E7018, E7024, and even stainless rods like
E309L. However, this unit is not designed to weld with E6010 and
should not be attempted. Performance with E6011 may be brand
dependent. You may need to experiment with different brands to find
the best one for your use. This is of course true for all welding rods,
but especially for E6011 with this machine. For general purpose fab-
rication, and practical use, consider using E7014. This is considered a
“
fabrication rod
”.
With this rod, high
-
quality, rapid, self
-
releasing
welds can be made, without having to have a hot box that is required
to maintain low
-
hydrogen type rods such as E7018, which has similar
tensile strength. E7014 rods are particularly easy to use, and leave a
smooth, high quality appearance, even in the hands of novice users.
The E7014 can be easily drug along the work piece while maintaining
an arc. The slag is medium heavy and will self release if the amp
range and technique is correct.
While in Rapid Set mode, if you de-
cide to use E7014 select E7018. For all others listed that are not
listed in the Rapid Set mode, use manual mode only.
IMPORTANT: Whenever welding, this unit performs best when a tight,
close arc is held. Long arc lengths will create arc outages.
This welder has a maximum output of 180 Amps while stick welding
on 240V. This is sufficient to weld with most
5/32”
welding rods.
Running larger rods may be difficult and may make the duty cycle
interrupt or over current interrupt engage. When operating on 120V,
use a
3/32”
or smaller welding rod. Operation at higher than 85A
while on 120V may trip a 20A circuit breaker.
Work Clamp
NOTICE: In AC mode, the electrode holder should remain in the positive (+)
terminal. Only change/swap torch/work clamp position for DCEN (
-
) when need-
ed. Use in DCEN is very rare and should only be changed for applications requir-
ing its use.
