This JOBMATE
TM
portable and gasless MIG/Flux-Core Wire
Welder Kit provides two heat settings, infinite wire speed
control, current overload protection and thermal overload
protection. The welder can be used for welding mild steel 20
gauge to 5/32" using flux-core wire and mild steel 20 gauge
to 1/8" for gas metal arc welding (GMAW).
Guidelines for proper usage and description
ON/OFF switch
This switch is used to turn the power supply of the welder ON
and OFF through the main transformer and control circuit.
MIN/MAX 1/2 voltage setting
Two adjustment switches are provided on the front panel of
the welder kit, for setting the minimum and maximum values
of voltage and tension. Refer to the set up chart for initial
adjustment of the voltage setting.
Wire speed adjustment knob
This knob adjusts the wire feed speed.
Ground cable and clamp
The ground cable and the clamp are attached to the workpiece
to form a closed circuit which allows the flow of current needed
to weld.
Welding cable and MIG gun/torch
The welding wire is driven through the welding cable and the
MIG gun/torch to the workpiece. It is attached to the drive
system and the gun trigger activates the drive motor.
Thermal indicator
If the duty cycle of the welder exceeds the maximum level, the
internal temperature of the welder will exceed the allowable
operating range, which in turn makes the thermal overload
light glow and causes the welder to shut down automatically.
Allow the welder to cool down for 20 minutes until the thermal
overload light turns OFF automatically. The temperature of the
welder is then within the allowable operating range.
Power cord
The power cord connects the welder to the 120 V power supply.
Connect the 15 A plug into a 120 V/20 A receptacle to supply
power to the welder.
Hand-held welding shield
The welding shield is provided with a filter glass to protect
the face, eyes and gloved hands of the operator from radiated
heat, spark, intense ultraviolet and infrared rays during the
welding operation.
Chipping hammer / wire brush combination
The pointed chipping hammer side of the brush is used for
quick removal of the welding slag from the welding bead. The
wire brush is used for cleaning contaminants such as dust, dirt,
grease and welding slag from the base material.
