arcweld 200i-ST - Summary; General Introduction; Welding Capability; Volt-Ampere Characteristic

SUMMARY
GENERAL INTRODUCTION
The arcweld
®
serie machine is a general MMA arc welding power
source which utilized single phase input power. The arcweld
®
inverter machines adopt the latest Pulse Width Modulation (PWM)
technology and Insulated Gate Bipolar Transistor (IGBT) power
module. The welding response of the inverter machines has been
optimized for Stick(SMAW) and TIG(GTAW). They are an ideal
choice for maintenance, small repairs & general fabrication where
portability is important.
The arcweld
®
130i-ST and arcweld
®
130i-ST DV is recommended
for stick welding with such popular electrodes as E6011, E6013
and E7018, with diameters up to 1/8” (3,2mm). The arcweld
®
160i-ST DV is recommended for stick welding with such popular
electrodes as E6011, E6013 and E7018, with diameters up to
5/32” (4,0mm). The arcweld
®
200i-ST and arcweld
®
200i-ST DV
is recommended for to stick welding with such popular electrodes
as E6011, E6013 and E7018, with diameters up to 3/16” (5,0mm).
It features automatic arc control to adjust the arc force, hot start
and anti sticking.

200i-ST DV adopt power factor
correction (PFC) technology, which extend the input voltage to a
wide range(98V~-265V~), and it can reduce the harmonic current.
SMAW - Shielded Metal Arc Welding.
PWM - Pulse-Width Modulation.
IGBT - Insulation Gate Bipolar Transistor.
TIG - Tungsten Inert Gas welding.
PFC - Power Factor Correction.
DV – Dual Voltage.
WELDING CAPABILITY
Please see Technical Specications in the Installation Section for
rated outputs for arcweld
®
inverter machines. It is capable of higher
duty cycles at lower output currents. If the duty cycle is exceeded,
a thermal protector will shut off the output until the machine cools.
The picture below will show what means duty cycle 60% for
example.
VOLT-AMPERE CHARACTERISTIC
Arcweld
®
Electric machine has excellent volt-ampere characteristic,
refer to the following graph. In MMA welding, the relationship between
rated load voltage U2 and welding current I2 is as follows:
I2 ≤600A,U2=20+0,04 I2(V); When I2>600A,U2=44 (V)

TILTING
Place the machine directly on a secure, level surface. Do not
place or operate the machines on a surface with an incline greater
than 15°C from horizontal. The machine may topple over if this
procedure is not followed.
Weld for 6
minutes
Break for 4
minutes
