Installation Instructions for 81540 
MIG100 Gasless Welder 

 
PLEASE READ MANUAL CAREFULLY BEFORE USING. 
 

SAFETY INFORMATION 
 

Before using welder, please ensure that you know: 
 

1.  Arc welding can be dangerous. 
2.  This welding machine must be connected to a power source in accordance with appliance electrical codes. 
3.  For safety turn off and unplug machine when installing new wire spool, adjusting wire tension roller or replacing 

contact tip. 

4. 

The contact tip is electrically “hot” and if it contacts the grounded work piece it will cause damage. 

5.  All installation, maintenance, repair operation of this equipment should be performed by qualified technicians in 

accordance with national, state and local codes. 

6.  Electric shock could kill.

changing wire spools. 

8.  Fumes and welding gases can be dangerous. 
9.  Welding sparks can cause fire or explosion. 
10.  Arc rays can burn. 
11.  Hot metal will burn. 
12.  Electromagnetic fields may be dangerous.
