- Page 4 Transport Unloading Never underestimate the weight of equipment, never move or leave suspended in the air above people. Use recommended lifting equipment at all times. WARNING! Falling Equipment can cause injury. Never lift welder with gas bottle attached. Never lift above personnel.
- Page 5 Allow machine to sit for 5 minutes minimum to allow the power capacitors to discharge before working inside this equipment. Do not touch electrically live parts The POWER MTS175S Inverter Welder requires a 230V 50/60Hz 29amp power supply. It comes with a 3 metre mains cable attached.
- Page 6 POWER MTS175S is rated at 150 Amps(MMA) at 35% duty cycle on a ten minute basis. If the duty cycle is exceeded a thermal protector will shut machine off until the machine cools.

- Page 8 The torch trig-ger function is designed to operate for both MIG and TIG functions. To operate in 2T mode, the trigger on either the MIG or TIG torch should be simply held down. The 4T function operates as a torch “latch” in MIG mode that locks the MIG torch on without needing to hold the trigger. To operate 4T in the MIG mode, simply press the torch trigger and hold it down until the arc starts.

Disconnect TIG Torch switch plug from torch control socket and connect plug from foot pedal Positive power connector + Connect the earth lead to by inserting and twisting until tight and the earth clamp to work/bench Connect the gas input hose to gas regulator and use 'Pure Argon' Gas, available from local suppliers. - Page 11 Connect the earth lead to by inserting and twisting until tight and the earth clamp to work/bench Connections for STICK MIG /MAG Welding Setup machine as per two diagrams below: Rear machine connections TO INSTALL WIRE: 1. Loosen top idler tensioner, rotating counter-clockwise 2.
- Page 12 Connect Euro type MIG torch to euro torch connector To avoid shock keep the MIG torch in good condition and replace if any of the insulation is damaged. Connect the earth lead (negative - ) to work/bench. Connect the gas input hose to gas regulator, Set gas flow/pressure to 10-14 LPM, in drafty or open areas a higher flow may be required to stop porosity of weld.

- Page 15 4. Select the filler wire type. Fe= Steel, Al= Aluminum, SS= Stainless Steel. 5. Select 2T or 4T function. 2T is simply press and hold the torch trigger to start and activate the torch. 4T re-quires the trigger to be pressed to start the arc. Once started, the trigger should be released to weld.

workpiece welding will start, to stop welding release torch trigger. Adjust wire feed speed to give desired weld characteristics Less wire = Dip transfer welding More wire = Spray transfer welding TIP: Inside wire feed lid is chart with approximate recommended welding power settings required for various sizes of material. - Page 17 The second column labeled possible cause lists the obvious external possibilities that may contribute to the machine symptom Step 3 Recommended course of action This column provides a course of action for the possible cause, generally it states to contact welding for repair of machine.
