Thank you for choosing a BOSSWELD POWERPULSE 250PFC Inverter MST Welder
In this manual you will find instructions on how to set up your welder along with general welding information,
safety information and helpful tips. We encourage you to go online to our website for more tips and
troubleshooting as well as many welding resources.
The POWERPULSE 250 is a new inverter-based MIG/MMA/TIG Welding machine with Synergic Programs and
Dual pulse functions. The MIG function allows you to weld with Gas Shielded wire applications giving excellent,
professional welding results. Easy step-less adjustment of voltage and wire feed coupled with integrated digital
meters allows easy setting of welding parameters. The POWERPULSE 250 features MIG welding with
Synergic welding programs designed for ease of use with your selected gas mixture. The operator selects the
gas mixture and wire diameter they are using then simply start welding. Once this is done the operator can
make fine adjustments to the voltage for even greater control of the weld pool. The added Lift-Arc DC TIG
capability delivers perfect arc ignition every time and a remarkably smooth stable arc produces high quality
TIG welds. TIG functionality includes adjustable Down Slope & Post Gas as well as being gas solenoid-valve
equipped. The stick welding (MMA) capability delivers easy electrode welding with high quality results, includ-
ing cast Iron, stainless and low hydrogen. An additional feature is the Spool gun ready function that allows the
simple connection of Spool Gun for the use of thin or softer wires that don’t have the column strength to feed
through MIG torches, such as aluminum wire. In the JOB mode, 100 different JOB records can be stored and
called , improve the quality of welding process .
Arc welding with the POWERPULSE 250 machine t is suitable for all positions welding for various plates made
of stainless steel, carbon steel, alloyed steel etc. Applications applied to pipe installment, petrochemical,
architecture equipment, car repair, bicycle repair, handicraft and common steel fabrication.
The POWERPULSE 250 machines has built-in automatic protection functions to protect the machines from
over-voltage, over-current and over-heat. If any one of the above problems happens, the alarm lamp on the
front panel will light up and output current will be shut off automatically for the machine to protect itself and
prolong the equipments life!
Every effort has been made to ensure that this manual has been prepared accurately, however errors and omissions are excepted.

M
MIG
• Simple to learn
• MIG Wire is fed through the gun to create the weld pool
• Gas or flux prevents oxidisation in the weld
• Weld with or without gas
• Point and pull the trigger
• Great for maintenance, small projects
& automotive repairs
METAL TYPES
Mild steel, stainless steel & aluminium
S
STICK
• Easiest process to learn
• Best choice for quick repairs
• Slower than MIG welding
• Forgiving in dirty/rusty environments
• Not recommended for thin sheet metal welding
METAL TYPES
Mild steel, stainless steel & cast iron
T
TIG
• Gives a better weld finish
• Accurate heat control
• Considered the most challenging process to learn
• Good way to weld thin material
• Argon gas is required
METAL TYPES
Mild steel, stainless steel & aluminium
P
PLASMA CUTTING
P
• Wide range of uses to cut conductive metals
• Uses an accelerated jet of hot plasma
• High speed/low cost cutting method
• Used extensively replacing gas cutting methods
• Air compressor is required
METAL TYPES
Mild steel, stainless steel & aluminium
