Installation and Operator Instructions 

 
Read this entire section before installation or operation 
of the machine. 
 

Location and Environment 

This machine will operate in harsh environments. 

 

However, it is important that simple preventative 
measures are followed to assure long life and reliable 
operation. 

  Do not place or operate this machine on a surface 

with an incline greater than 15° from horizontal. 

  Do not use this machine for pipe thawing. 

  This machine must be located where there is free 

circulation of clean air without restrictions for air 
movement to and from the air vents.  Do not cover 
the machine with paper, cloth or rags when switched 
on. 

  Dirt and dust that can be drawn into the machine 

should be kept to a minimum. 

  This machine has a protection rating of IP23.  Keep it 

dry when possible and do not place it on wet ground 
or in puddles. 

  Locate the machine away from radio controlled 

machinery.  Normal operation may adversely affect 
the operation of nearby radio controlled machinery, 
which may result in injury or equipment damage.  
Read the section on electromagnetic compatibility in 
this manual. 

  Do not operate in areas with an ambient temperature 

greater than 40°C. 

 

Input Supply Connection 

Check the input voltage, phase, and frequency supplied 
to this machine before turning it on. The allowable input 
voltage is indicated in the technical specification section 
of this manual and on the rating plate of the machine.  
Be sure that the machine is grounded. 
 
Make sure the amount of power available from the input 
connection is adequate for normal operation of the 
machine. The fuse rating and cable sizes are both 
indicated in the "Technical Specification" section of this 
manual. 
 
The machines are designed to operate on engine driven 
generators as long as the auxiliary can supply adequate 
voltage, frequency and power as indicated in the 
"Technical Specification" section of this manual.  The 
auxiliary supply of the generator must also meet the 
following conditions: 

  Vac peak voltage:  below 670V 

  Vac frequency:  in the range of 50 and 60Hz 

  RMS voltage of the AC waveform:  400Vac ± 15% 

 
It is important to check these conditions because many 
engine driven generators produce high voltage spikes.  
Operation of this machine on engine driven generators 
not conforming to these conditions is not recommended 
and may damage the machine. 
 

Output Connections 

A quick disconnect system using Twist-Mate

 cable 

plugs is used for the welding cable connections.  Refer 
to the following sections for more information on 
connecting the machine for operation of stick welding 
(MMA) or TIG welding (GTAW).  

  (+) Positive Quick Disconnect:  Positive output 

connector for the welding circuit. 

  (-) Negative Quick Disconnect:  Negative output 

connector for the welding circuit. 

 

Stick Welding (MMA) 

This machine does not include a MMA welding kit 
cables, but may be purchased separately.  Refer to the 
accessories section for more information. 
 
First determine the proper electrode polarity for the 
electrode to be used.  Consult the electrode data for this 
information.  Then connect the output cables to the 
output terminals of the machine for the selected polarity.  
Shown here is the connection method for DC(+) welding. 
 

 

 
Connect the electrode cable to the (+) terminal and the 
work clamp to the (-) terminal.  Insert the connector with 
the key lining up with the keyway and rotate 
approximately ¼ turn clockwise.  Do not over tighten. 
 
For DC(-) welding, switch the cable connections at the 
machine so that the electrode cable is connected to (-) 
and the work clamp is connected to (+).
