Mma Welding - ESAB Caddyt Arc 150i Service Manual

MMA WELDING

The CaddyArc 150 gives direct current, and you can weld most metals to alloy and
non--alloy steel, stainless steel and cast iron.The CaddyArc 150 allows you to weld most
coated electrodes from ∅ 1.6 to ∅ 3.25.

Hot start
Hot start increases the weld current for an adjustable time at the start of welding, thus
reducing the risk of poor fusion at the beginning of the joint.
Arc force
The Arc Force setting alters the machine's dynamics. A softer/harder arc can be obtained.
The arc force is important in determining how the current changes in response to a change
in the arc length. A lower value gives a calmer arc with less spatter.
Hidden functions
The setting options for drop welding and ArcPlust, are obtained by pressing the
hot start and arc force
The display then shows a letter and a number.
Function
d = drop welding
F = welding control ArcPlust
Select function by pressing the arc force or hot start button.
Select setting with the setting knob.
Leave hidden functions by pressing the hot start and arc force buttons simultaneously for 1
second.
Drop welding
Drop welding can be used when welding with stainless electrodes. This technique involves
alternately striking and extinguishing the arc in order to achieve better control of the supply
of heat. The electrode needs only to be raised slightly to extinguish the arc.
Welding current control - - ArcPlust
The CaddyArc 150 is supplied with ArcPlust, a type of control that produces an intensive,
concentrated and calm arc. It recovers quickly after a drop short--circuit, which reduces the
risk of the electrode becoming stuck. In most welding applications the best result is
achieved if ArcPlustis On.
